Been using for awhile

Like this app for fastening timer and water log, but I don’t use it to log food. Found nutritional values are usually too generic and usually wrong. I use another app that has a way better nutritional library for foods. Scanning using their tool also never works so I had to hand-key foods in. That got old fast! Recipes are too high in carbs for my choices so don’t use that part of the app either.

Keeps me on track!

The free version has helped to keep me on track. The timers are great. The reminders are helpful. I’m too cheap to upgrade so I’m limited to the free features. They are sufficient. I would like to adjust the plan windows but for now I’ll do the math in my head.
