Aviation Glass Cockpit / EFIS with ADS-B "Radar" display
About this app
Kwik EFIS is a Glass Cockpit application designed to work on most Android devices. It provides a modern aviation glass cockpit attitude and flight instrument display.
Digital Moving Map
The built in map module provides situational awareness and and navigation functionality. EFIS can optionally integrate with the Stratux ADS-B/AHRS to provide real-time traffic overlay.
Synthetic Vision
Synthetic vision is built from the USGS 3 arc second Digital Elevation Model data. If enabled, it also allows for some terrain collision detection. The required terrain data packages are available via F-Droid, see:

Flight Director
Kwik EFIS has a fully functional flight director built in. It uses the standard V-Bar symbology common to modern flight directors. The target waypoint and altitude is set on-screen by means of the spinner controls on the right top and bottom of the screen.
Airspace
Airspace data is provided from Worldwide Soaring Services Turnpoint Exchange Airspace (http://soaringweb.org/Airspace/)
ADS-B/AHRS
In addition to the internal sensors, a low cost Stratux ADS-B/AHRS can be selected as the input source. See http://www.stratux.me/ for more information.
Simulator
There is a simulation mode available in the application. The Flight director is used to select a waypoint and altitude and the simulator will generate the GPS movements to navigate to the selected waypoint. The speed is set at the typical cruise for the currently selected aircraft.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be player.efis.pfd is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 8.02 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Kwik EFIS first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Kwik EFIS, and a listing is removed when the evidence for it stops holding up.
