Comments on 12Hours for Android

★★★★★ A Google User · Sep 25, 2014
Incredibly helpful I'm time-blind (common symptom of ADHD) and visually oriented so analog clocks have always been a natural choice for me; translating time into "slices" of a clock face. This widget extends that concept in a wonderfully elegant and useful way. The one feature request I would make is maybe an optional "12 Hours + 60 minutes" - with the next 12 hours on the rim of the clock and the next hour shaded on the face. Gives a better idea of the time to the next appointment while keeping a snapshot of the day.
★★★★☆ A Google User · May 26, 2015
Android wear I would love to see this watch face on my urbane! Great app otherwise
★★★★☆ Mike Atkinson · Jul 28, 2016
Near perfect. If I could give 4.5 I would! Am I expecting too much? If I could get the ability to support Touchdown calendar too (supporting my company's calendar in the secure zone in addition to my personal calendar) then that would be the icing on the cake. Pure calendar can do this, but not in such a useful widget. Occasionally I need to go into the settings to refresh the clock - it seems to miss some events from time to time - and as another review has said I have some zombie widgets listed that cannot be removed.
★★★★☆ D_123 · Oct 16, 2021
10/16/2021 UPDATE: still first app I install. I'M ADDICTED TO the giant analog clock segmented with colored calendar events. 4.5 STARS. Using this for years now. Some quirks, in that it's not consistent in keeping the gradient and color settings of the widgets and sometimes have to reinstall; BUT a very small price to pay for the WONDERFUL functionality it provides. 5 STARS when the quirks are fixed, but this is one of the FIRST APPS I ALWAYS INSTALL on all my phones and tablets. FANTASTIC!
★★☆☆☆ A Google user · Dec 12, 2018
Wonderful app but looks to be abandoned. Recently stopped working on S8 Oreo. Only the hands show now, not the clock face.
★☆☆☆☆ Дмитрий Примак · Jul 3, 2020
Why did it begin to require installing Google Calendar?! It had been working without it properly!! (I have been using Samsung calendar)
★★☆☆☆ A Google User · Jan 28, 2015
The watch face doesn't show up on my watch.
★☆☆☆☆ stefan ketola · Dec 27, 2016
Installed it. It did nothing. No menu to bring up to change settings or anything. It just sat there. It said to add widget, but again no menu to open up or anything to give one a clue how to add a widget. A 0 stars app. Uninstalling now

Description by Michał Tajchert Written by the developer, not by AppBrain. Click to read.
Analog clock? Day planner? 12Hours is both at the same time, with a unique and eye catching design.
What is it? It's an analog clock widget which automatically gets all your calendar events in the next 12 hours and shows them as marked zones on a clock. Simple as that!
What does it do? It shows you all your events in the next 12 hours at a glance, making it easier than ever to plan your day.You can see exactly when and how long your events are just by looking at your phone, so you'll never have to wonder if you're missing a meeting with your boss for that steak again.
PROBLEMS?
Make sure to use official GOOGLE CALENDAR app.
If you added an event and it is not there, it's because the widget refreshes each 30 minutes - can't do better than that.

Recent changes:
Dark clock widgets, custom and transparent clock backgrounds, and configurable widget tap actions. Plus refreshed previews, translations, and stability improvements.
