Dark mode is broken

In a recent update, when using the app in my dark room to develop sheet film, when I select, dark mode, there is still a bright white dynamic island where the mode selector is, contributing significant light pollution into my space. I’ve had to tape it off with black tape to make it usable. Why did you implement this? Is it a bug?!

Dark mode no longer dark!

In the darkroom, I rely on the ability to turn the screen of my iPhone to dark mode when using this app to time film development (sheet film, in trays). But in a recent update, there is now a large white “Dynamic Island” where the mode buttons are that cannot be turned dark, so there’s significant light pollution in my workspace when developing film, and I have to put black tape over that part of the screen!! WHY did you implement this?? Is it a bug or a “feature”??!

Could be so much better

Timer works fine, that’s the important part. But the UX around the whole app is just bad. It hard to scan the list in My Times (why no search?), can’t bulk delete, can’t sort or group.
No separate utilities like the volume mixer.
Please take some time to improve the app, there’s so much potential here.

Good overall

Good app but turns music off while your using it

GROSSE ARNAQUE

Honnêtement je suis très très déçu, payer 9€ pour de fausses informations et en plus incomplètes car l’application ne donne que le temps de développement pour 20 C. C’est très moche de faire ça je vous déconseille fortement cette application sincèrement fuyez !
