Ratings and reviews

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

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.

Works absolutely great.... for 1 week. Then just completely locks you out. Zero functionality unless you pay. Nothing works after 1 week. And the purchase button doesn't even work.
