There is a bit of a learning curve and there are some rare occasions when trying to modify and save a roast curve fails BUT, once you have gained experience with it, it is actually quite powerful. Manual roasting with the ability to save and modify the resulting profiles for future use is quite convenient. The preloaded roasting profiles are more frustrating than effective. I have the VIP subscription too which quite honestly I never use. Full manual roasting is the way to achieve maximum result

Pixel 6 Non Operable. Translated app from Chinese to English so a little quirky. Biggest issue is while I could connect to my R1, the Start button for beginning the roasting sequence did not function. I had to download to an iOS device which worked much better. 2024 people and there are more Android devices in the world than iOS.

Make it easier to make custom profiles. Needs the ability to export and import profiles in excel format, so you can modify from a computer and easily share them. It crashes sometimes in the middle of a roast and now I have no way to monitor. The app should be able to pull the status of the roast from the roaster in the even if an app crash. Needs a manual roast setting in the app that lets you adjust rotation speed, heat, and fan speep. It should log your adjustments and create custom profile
