What is Cometin
Cometin is a free*, growing collection of tweaks and tricks to optimize your productivity and improve the Android experience.

More information
I can create a separate app for every idea I have. But why shouldn’t I put everything in 1 app?
Google announced Dynamic Modules at the IO in 2019

With dynamic features you can split an app into several parts. This is exactly what Cometin is.
Cometin is a growing collection of tricks and tweaks for your Android device, split into modules.
This way you only download the features that you want to use and save your storage space.

Available modules (with some small descriptions)
Ambient display
bring a customized Ambient display, Always-on-display and wave to wake to your device
App locker
Lock apps behind a passcode or pattern
Better rotation
Forces every app to be compatible with every orientation including 180 degrees
Keep your screen on for a certain amount of time
Cometin Sync
Sync notifications, and notes between phones and desktops
Darker brightness
Go below the minimum brightness by applying a dark overlay on top of your screen
Flip to shhh (Cometin 2.0 and up)
Flip your phone face down to silent notifications (except alarms)
Hide head-up notifications
Hide statusbar, navigationbar or both
Create a work profile to seperate personal and work.
Remap assistant
Execute a different action when opening the assistant
Shake actions (Cometin 2.0 and up)
Execute a different action when shaking the device

Is this safe?
Yes! All modules are only served from the Google Play Store, all modules are scanned by Google Play Protect so nothing to worry about!

Installing modules:
The installation of modules is done immediately, and you can use the module immediately after installation.

Updating modules:
Installed modules are automatically updated together with Cometin. No hassle with separate files!

Removing modules:
Module uninstalls do not occur immediately. That is, the device uninstalls them in the background in the next 24 hours or with a new Cometin update.

Request for new features:
Requests for new features are always welcome! However, I cannot promise anything about the actual arrival of these features.
Request your features via my support ticket system: This way you can keep track of the status of features.

Need help or got problems?

What permission Cometin asks for and why
Every permission makes sense, and descriptions in the system settings explain which modules make use of what permissions.

* In order to use more than 5 modules at the same time a small donation is required.

Cometin Cloud

What is Cometin Cloud
Cometin Cloud is a cloud service for storing data so that it can be retrieved on other devices. Cometin Cloud consists of a database where information is stored temporarily and securely.

Deleting/managing data
When creating a Cometin Cloud session, a unique ID is created under which information is stored. You can permanently delete all information at any time. In addition, all information is automatically deleted after 1 month of inactivity.

Cometin user reviews :

I literally can’t wait for what modules will come out next! This whole app does feel a bit like it’s in beta, for example the modules take a while to enable and disable but they still work. Oh btw to enable a module you have to enable it from the manager and from the module itself.

Changed from 1 to 5 star, only reason for 1 star I couldn’t figure out how to remove my ‘work profile’ as I decided against using it. Emailed the maker of the app. He got back to me within minutes with a simple ‘how to guide’ it worked perfectly. 5* brilliant service.

Good idea… But then the tasker integration. In this app every task can be execute using Tasker particularly so what is the purpose for that integration??

There is a problem that even when I disable the better rotation it keeps rotating and my auto rotation is off

I don’t know why this app is getting so much hate, the module I’ve installed works just fine. It is a very interesting app.

I turned on better rotation and now i cant turn it off. Edit: i fixed to by turning off privileges. I tried to turn it off through the app but it just said it turned of but it didnt do anything.

  • How can’t you turn it off? There are multiple way to turn off the module. Using the QS, through the app or tapping the stop button in the notification.
