Myardage's Achievements



  1. I'm happy to announce the immediate availability of Myardage Lite. https://itunes.apple.com/us/app/myardage-lite/id1383286422?mt=8 This is a "lite" version of the application that allows you to try out the app with the following limitations: 1) No automatic weather updates are included, so you must enter the current conditions by hand 2) Club customization is disabled, so you must use one of the included club defaults instead 3) Up to 7 clubs may be entered at any given time The lite version is no charge and will never expire. It will let you play around with our algorithms and determine if Myardage is a good fit for you and your game. If you are interested in lifting these restrictions, please check out our paid version of the app instead.
  2. Check out our first review MYGOLFSPY fans http://flagstick.com/golf-equipment/product-watch-myardage-app/
  3. If anyone else would like a promo code to try out the app, please feel free to PM me and let me know, and I'll send a complimentary code your way. We'll be handing out codes for Mygolfspy members until the end of March. I'd post more codes here, but apparently it can be a bit of a pain to go through them and try them all out, especially if they've already been taken (we don't have any way of tracking which ones have been used over here, so the only way I know for sure is if someone tells me they've used a specific code).
  4. Just a quick update... We've not yet heard back from the USGA as to whether or not our app is legal for tour play, but the general consensus at the moment is that it should be. Everyone we've talked to has been quick to point out that you're not allowed to take local measurements with any kind of handheld device (be it a phone or something else), but you are allowed to access weather related information (such as the altitude, temperature, barometric pressure, and humidity) based on your current GPS coordinates. Since we don't take any local readings and all our information is derived from user entered data and the weather information pulled down from the internet, there's really no reason why we shouldn't be legal for tour play. Likewise, we've also reached out to the R&A, though we're currently waiting to hear back from them as well.
  5. Primarily Objectice C with a few bits written in C for performance reasons. There is no Swift code and we're relying on the Apple APIs for just about everything (so we're not using any third party libraries for anything).
  6. If that's in Fahrenheit, that's pretty cold. A lot of the carry distance instability at low temperatures tends to come from the material composition of the golf ball freezing over, which is actually something we consider in our calculations (above and beyond the change atmospheric density). If you've ever wondered why the clubs have a "customize club" button on them, that's what some of those values tweak- they change how our algorithm computes the transfer of energy from the club head into the golf ball, which is something that can vary as the air gets colder and the golf ball gets harder. This also works in the inverse- beyond a certain temperature, the golf ball can become somewhat soft, causing you to lose some distance in extreme heat (though that loss is often negated by the positive effects of the warmer air, so it's not something you'll typically see unless you're overriding the conditions and really pushing the numbers around). The only thing the "Update current conditions" button does is to try and pull down the weather from the internet. It has nothing to do with the actual calculations of your club distances- those will occur whenever you change anything within the app that would alter those numbers. If you're just trying to keep the weather updated, then the app will normally try to do this for you out of the box. By default, it will update the weather every hour- assuming the app is open and in the foreground. If the app was closed or pushed into the background and an hour has elapsed, then it will automatically trigger a weather update as soon as you open it again. Likewise, you can actually change the weather update interval over in the settings section (or disable them entirely if you'd like). The shortest interval you can select is 15 minutes. Pressing the manual update button has the same effect as an automatic weather update- that button is really just there for people who want to watch the weather change in real time, or have some other reason to force an update. We are considering an Android version, though I'm not sure when that will happen. We're just a team of two people at the moment, and I'm not familiar with the Android ecosystem at all (nor do I have any Android hardware for debugging and development). If the iOS version is moderately successful, it's certainly something we'll be looking into as soon as possible.
  7. Just a quick note- as far as I know, two codes are still available for anyone else who'd like to check out the app. H3R7EMHY636R A9Y4FMEHWTJJ TEYPL4RWMTEX If they don't work and you'd still like to give the app a shot, please let me know and I'll generate a couple extra codes.
  8. Hey, thanks for the review! Just out of curiosity, is there anything you think we could improve on the app? Are there any particular features you'd like to see in the future?
  9. Thanks for your comments! We have considered a "lite" version, but we're not really sure how to go about that at the moment. If we submit a separate application, then there's no way for users who download that version to transfer their clubs to the full version, should they chose to purchase a copy. We could restrict the version we've already got and have the user unlock additional features via IAP, but we didn't want to charge our users anything past the initial price- there's too many iOS apps out there with "strings attached", and we didn't want to be one of those guys. Unfortunately we don't support distances based on wind conditions. It was something we were looking into at one point in time, but I could never find a real time source of data that was fast enough or accurate enough to generate any sort of usable information. Out here, our wind is often very violent and unpredictable. It rises and swells, then cuts out, then blasts you a few seconds later. It didn't seem like anything I could practically predict or model, so we made the decision to forgo that and focus on the stuff relating to atmospheric density instead. We don't know if it's USGA legal. Their rules allow the use of internet based weather services, but disallow anything that might give you a local "reading" from the device itself. The specific example they give of this is an anemometer for measuring wind speeds, but they don't mention using the GPS receiver to ascertain the phone's current location for weather updates. At the same time, a lot of weather related applications use the GPS to hone in on your current location for more accurate weather readings, and they specifically state that "weather related applications" are allowed- so it could very well be legal. I've sent an email to them requesting verification on those rules, and asking them if they think our system is legal or not. I'll post an update here if I hear back. That's exactly how it works. Once you've put in your stock distances, you need to set the "previous conditions" to the weather conditions that best represent the conditions that existed when you shot those distances. For example, if you know your driver goes 260 yards on a warm summer day, then that's what you need to set the previous conditions to. After that's done, the app will automatically update the current conditions whenever it can, and automatically recalculate your numbers for you. Note that you can actually override any of the current conditions to whatever you want... If the app auto-updates the weather and says the ambient temperature is 22°C, you can go in and edit that value to whatever you want, just to see how changing that value will affect your numbers. If you want to revert back to the automatically updated value, you can tap on the "unlock" button that shows up next to an overridden value, and it'll switch back to the automatic value. The app will also clear out any values you've overridden after 12 hours, just so you don't accidentally forget about them. We've found that a lot of people actually have a lot of fun just sitting around fiddling with the current conditions- because you can find out how far your clubs are going to go in London, or Amsterdam, Florida, California, etc. You can also push the numbers pretty far in either direction and do some silly stuff like seeing how far your clubs would go at the top of Mount Everest. I don't know how practical that information would be, but our calculation core is robust enough that the results should be reasonably accurate.
  10. We don't normally do this, but since you guys seem to be on the fence about the app... Here's five promo codes that you can redeem to download free copy. H3R7EMHY636R A9Y4FMEHWTJJ TEYPL4RWMTEX XKPRY6R4W7LR ETL4NM6FRNRK We don't have any in-app purchases, subscriptions, or other hidden costs. What you see is what you get. This is for the full version (which normally sells for $6.99) and includes free weather updates for life. If you're curious to see what it's all about, grab a promo code and give it a shot. Maybe you find it useful, maybe not. I would ask that if you redeem a code, you reply with the code you've used so I can strike it off the list (since there's no way for me to tell which codes have been redeemed on my end). You can redeem these codes through iTunes or on your iPhone/iPad. On iTunes, there's a "Redeem" link on the right hand side of the "iTunes Store" section where you can enter in a promo code. On iOS, you can open the app store app, then scroll to the very bottom of the first page- you'll see a redeem button you can tap to bring up a screen where you can enter in the code. PS: We're obviously not expecting anything for these. They're strictly for you guys to download and mess around with, if you want.
  11. I don't entirely mean to answer your question with a question- but if you want to hit a green, don't you need to know how far your clubs are going to carry? If you laser your shot and it says 220 yards, wouldn't you want to pick the club that carries 220 yards? What if 200 lands you in a bunker, and 240 puts you in a pond? That's who our app is for. Your carry distances are linked to your altitude and weather, and our app totally eliminates all the guesswork associated with that. There's so much technology out there that tells you the distance to the hole, but there's nothing out there that tells you how far your clubs are going to carry. That's exactly what our application is designed to do. So I'd say it's valuable to anyone who wants to see how the environment is constantly affecting their game from one day to the next, or anyone who constantly travels to new golf courses (as altitude is one of the major things we use in our calculations).
  12. Our technology is based on a combination of original research, papers published by the USGA, and other sources of information relating to the study of atmospheric science (including topics such as density altitude and atmospheric density in general). Trackman is likely basing their statements off the simple fact that the barometric pressure and temperature often change together. If you've got a heavy storm rolling in, you'll typically see a drop in barometric pressure (increasing the distance of your clubs) followed by a drop in temperature (reducing the distance of your clubs). This can sometimes negate the effect the barometric pressure has on the flight of your golf ball, but not always... It really depends on what the weather is doing, as well as any other geological features that might be nearby (such as mountains or valley). I should also note that things like this really depend on what sort of club you're hitting, and what the flight trajectory of the ball looks like. High spin clubs behave totally differently than low spin clubs, and are affected by the environmental variables in different ways. This is another reason why you can't really apply a standard rule of thumb to everything- not all clubs are the same, so you can't apply the same rules to all of them. We've solved this issue by including a set of default clubs in our application that you can pick from, which include an averaged set of club parameters like the launch angle, loft, spin rate, etc. The averages are good enough for most people, but you can dial in your numbers even more by customizing your clubs and entering in measured data from a device such as a Trackman (which, again, is completely optional). That being said, if you were to create a Driver and a 9 Iron in Myardage and say they both go 200 yards (which I realize is totally unrealistic), you'd see different distance changes for either club. This is because the 9 Iron has a higher spin rate and a different trajectory than a Driver, which in turn alters how much (or little) the environmental variables affect those carry distances. I would like to point out that it doesn't actually take 6 minutes to get your numbers out of Myardage. Once you've setup your clubs (which is a one time thing for most people), that's it. You're done. Myardage can automatically update the current weather conditions (which is enabled by default), so all you have to do is open the app and wait a few seconds. This entire process takes about 5-10 seconds on a modern day iPhone. We've actually got a demo video of the whole thing right here: In this video, I've already setup a few clubs on my iPhone 4S. You don't actually have to enter in anything if you just want to find out what your distances are. You just open the app, wait a few seconds, and then your numbers will automatically update. This isn't something you have to stand around fiddling with- it's designed to be quick and easy to use, especially if you're trying to check it on the tee box.
  13. We believe our app is competitively priced for the utility it provides. People invest well over $400 on a laser range finder or a GPS watch all the time. If you can't see the value in something worth the cost of a sleeve of golf balls or a pint at the clubhouse, then you're likely not part of our target demographic. All four variables are required to calculate an accurate atmospheric density. Just ask an airplane pilot or a military sniper if the barometer ever factors into their calculations- because it does. Humidity isn't as important as the other three, but the barometric pressure is probably the worst of them. Depending on which direction it swings, you could be seeing distance changes that are the same as a 1000ft change in altitude (or more). How is that not important? As far as everything else goes, it's not just a simple formula. Different clubs create different ball trajectories through the air, which means the atmospheric density of the air affects them differently. Different spin rates cause the ball to behave differently as it soars through the air, which again will change how these variables affect the flight of the golf ball. Our application considers all that internally. It's not just a simple excel spreadsheet with a pretty face- there's some serious math going on behind the scenes to calculate the true effect of the altitude and weather on your carry distances. Here's some numbers I just ran, using the default clubs in our application: Altitude: 0ft Temperature: 71.6°F Barometer: 1013 hPa Humidity: 50% Driver: 260 yards 2 Wood: 220 yards 2 Iron: 195 yards Let's say we drop the barometer to 990 hPa, which isn't uncommon to see when severe weather is rolling in. Here's the new distances: Driver: 261.994 yards (+ 1.994 yard difference) 2 Wood: 221.324 yards (+ 1.324 yard difference) 2 Iron: 196.407 yards (+ 1.407 yard difference) Not much of a difference. Huh. Okay, well, let's crank up the barometer to 1090 hPa. Driver: 253.053 yards (- 6.947 yard difference) 2 Wood: 215.262 yards (- 4.738 yard difference) 2 Iron: 190.148 yards (- 4.852 yard difference) You're losing 7 yards on your driver due to the shift in barometric pressure alone. I'd call that pretty significant. This is roughly the same as a 2500 foot drop in altitude- that is to say, you would experience the same distance loss if you went down 2500 feet. How is that not something that golfers should be considering? Likewise, you can also see how these changes do not affect all clubs equally. Rule of thumbs are just that- a rule of thumb. They're wildly inaccurate as you get further away from the ideal use case, and let's face it- real life is almost never ideal. The altitude, temperature, barometer, and humidity can all combine to in various ways to create situations that a straight linear formula cannot accommodate for. There's more dynamics going on here than anyone previously thought- and our app is the first and only app to successfully calculate these numbers for any conditions you can imagine (quite literally, you can override the automatic weather updates and see how far your clubs would travel at the top of Mount Everest if you really wanted to).
  14. As per a prior recommendation in this thread, we've created a new post for our app over here: https://forum.mygolfspy.com/topic/22307-myardage-for-ios-see-how-the-weather-and-altitude-affects-your-golf-shots/
