开始圈钱了

之前用了好几年，挺好用的，虽然app要花钱，温控探头要花钱也可以接受，现在不充值不给你烘焙了，一年快3000块，之前下软件就交了一次费用，现在还想骗钱？

Stealth switch to subscription

I paid money for this app and now it suddenly switches to a subscription only service? I won’t be subscribing and I advise you to find another app to use. It is not that good.

Subscription???

I purchased the app with no mention of limited functionality and no mention of a subscription. Now I can’t use it without paying more than I was originally told. I hope the developer reconsiders his business model and grandfathers existing users.

Charge you for the app and then hit you with subscription

Been using this app for over 8 years. Updated today to find no longer usable without buying into tiers of subscriptions. Long time users are being locked out.
its sooooo fuuunits sooooo fuuun

Paid for the initial app years ago.

After close to 2000 roasts, they change up and want me to pay $4.99/mo.
No way! There are way too many free coffee roasting apps out there that do the same and perhaps better job of clocking roasts. Thanks but good bye! Too overpriced!
