### 5/5 — Tiddys

*2026-04-01*

Just wanted the review thing to stop popping up are you happy now

### 5/5 — Nice. I like the Lock Screen object

*2024-07-13*

Can you put this on GitHub? Verdi interesting, runs good. I like the Lock Screen summary when it’s running in background, very nice touch. What is that type of object called? It’s like a widget, but like toast. 

Also, the dark mode is a nice touch. Please keep privacy collection to a minimum, that’s one selling feature. Not a fan of ads, but it’s very minimal. 
Love this app! 

I would like to see the zone information again but I can’t figure out how to access it, since it’s not listed in the right-most menu currently.

Cheers
Great
