Roco: Dynamic Rotation Control

The easiest and fastest way to adjust screen rotation - small, intuitive, unobtrusive.

How it works

This app monitors your phone's orientation and shows a button when the phone is turned onto a new edge. Press the button to adjust rotation, or ignore the button and the rotation stays as it was.

This gives you the best of both worlds: ability to interactively adjust rotation whenever you need it (for example to quickly look at a picture in landscape), but without auto-rotate inconveniencing you in the wrong moments (for example when reading something while lying on your side).

Features

★ Freely customizable button position and size
★ Freely customizable color
★ Adjustable sensitivity
★ Show the button only on certain apps

An old version of the app has been featured on the (German) tech site Chip.de. Check out their video to see a small preview of the app's capabilites. Link: https://www.chip.de/video/Dynamic-Rotation-Control-verbessert-die-automatische-Bildschirmrotation-Video_137914846.html

Detailed Description

Positions can be chosen for landscape and portrait separately, so the button is always easy to reach, no matter how you're holding your phone. The color chooser includes a transparency setting which allows to make the button super unobtrusive. The sensitivity setting controls how far you need to turn the phone before the button is shown. And autostart means that you never have to open the app settings again after the initial configuration.

Permissions

The permission to access storage is needed if you want to automatically choose button colors that match your wallpaper. The app will only request this permission if you choose this option. If you prefer not to grant this access, the rest of the app works fine without it.

For the optional filter feature to work, the app always needs to know which app is currently in the foreground and to be notified when this changes (e.g. Are you watching a YouTube video or reading an E-Book right now?). Based on this information the app decides whether to show the button or not.
To access this information, the app uses a so-called "accessibility service". This is a highly sensitive permission, which in theory grants a lot of access to the device. Rest assured that this access is only used to make the filter feature work. No kind of personal information is ever stored or collected by this app.
This feature is optional, if you are not comfortable granting this permission, you can use the app without it.
