### 5/5 — Thank you for making this!

*2024-04-21*

I just wanted to say thank you for making this and pushing it all the way to production.
I use my Apple Watch as a back up, but on my second dive the other day, my primary actually failed, badly.
With your app, I was able to recover the Divelogs for that day! I was super gratified not to lose those, and it was easy to to the server and import them to subsurface.

### 5/5 — Fantastic Little app if you use subsurface

*2024-04-04*

This is a great if you use sub surface and an Apple Watch as a back up dive computer. You can easily send your data over to subsurface and have a quick reference for dive from the watch itself.
It’s a shame apple ultra watch reslly only usable as a true computer via a terrible subscription application and haven’t allowed other developers to deploy anything similar to protect their partner. Pretty ugly.
This app helps bridge that gap in a small but important way!
