Лучше найти не удалось, своих денег стоит. ### 1/5 — Stops timing if not open *2020-08-11* Learned the hard way that if you don’t keep the app open, it will simply stop timekeeping. I stand almost everything and just learned this the hard way. Wish there was a was some kind of warning about this. I guess my fault for using this with negatives for a client. ### 3/5 — Update Is Bad *2020-07-14* The update last month has made the app unreadable on my iphone if my phone is set to dark mode. It took me a while to figure out that I had to switch to light mode to see text again. This wasn’t an issue previous to this update, and I hope it is fixed soon. ### 4/5 — Update mit Schwächen *2020-06-06* Seit dem letzten Update gibt es ein Problem mit dem IOS Dunkelmodus und dieser App. Man sieht die Schrift nicht! Wenn man in den Geräteeinstellungen auf den Hellmodus wechselt ist alles wieder ok. Bitte nachbessern! ### 4/5 — Alles einwandfrei *2020-06-05* Eine geordnete App, welche ich für den C41 Entwicklungsprozess verwende. Das beste C41-Äquivalent für alle, die für s/w-Entwicklung schon die MassiveDev App verwenden - wenngleich es schade ist, dass beide Apps getrennt sind. ### 1/5 — Unfriendly and no data *2018-11-13* It could be me, but all you get is a few templates. The app show not exist and be merged with their near identical product. My advise is Do Not Buy! ### 4/5 — Its ok *2017-06-01* Does what it says but has some limitations. ### 4/5 — Decent app *2016-09-02* Would be better if it allowed you to enter new times ( if it allowed users to share data, that would be even better). Decent though. ### 4/5 — Works well, could be even *2016-04-28* Overall this works well for even most complicated processes. It would be great if you could rename and reorder each of the steps. Currently the app is limited to the names and orders of established processes, even though you can do practically anything with it. ## Frequently asked questions about Darkroom Lab Timer ### What photographic processes does Darkroom Lab Timer support?
