I can tell you that there are many golf apps available on the market, including ones that use your smartphone's sensors to measure slope and determine break. Some of these apps may require a subscription or a one-time purchase fee, like the Tour Read app you mentioned, while others may be free.
Before purchasing any golf app, it's a good idea to read reviews from other users and do some research to ensure that the app meets your needs and is worth the investment. Additionally, keep in mind that some golf courses may prohibit the use of certain technologies during play, so be sure to check with the course beforehand to avoid any issues.
