Ratings and reviews

I've used this very simple but functional app to track my biweekly medical injection for nearly two years. I opened it today to add my injection and was met with a "free trial ended" screen prompting me to purchase the premium version- with no other option to regain my data, I was forced to. There was no warning period or carryover of limited access for established users or a way to look at previous entries/download the data. I will no longer be using this app.

The fact that you have to pay to use the app AT ALL after a week is such a scam. I'd be fine paying for a one time premium upgrade if I still had the option for a basic version, like a single calendar with a preset check style, and additional calendars and custom checks as an upgrade. The app itself works great until you're completely locked out, which makes it all the more infuriating

Initially, i really liked this app because it was quite simple and effective. But now, it demands premium purchase for even adding a new habit. It says that the Free trial of the app is ended, about which it didn't mentioned before.
