### 5/5 — Request and Thank You

*2022-08-27*

This is everything I’m looking for. I just wish I could see my previous differentials so I can record them somewhere. It can be kept simple. I just need to know what my day previous was. Aside from that one request this app is amazing. As someone struggling to maintain weight it’s an anxiety saver. Would also love a complication or shortcut on the watch face.

### 4/5 — This is great!

*2020-07-24*

I love being able to see my caloric deficit so easily. It’s very motivating. I only wish there was a way to look at the progression of data over time on my phone. Something like a graph of daily deficit over a week, an average daily deficit over a week, plus total deficit for the week/month would be so useful. Otherwise, it’s great to have my daily deficit info at a glance.

### 5/5 — AMAZING

*2020-02-11*

The greatest!
