Editor's Overview

Kwik EFIS is a navigation application developed by F-Droid Open Source, packaged as a single Android APK of version 8.0 weighing in at 4.14 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 4.14 MB, so it installs quickly even on modest connections.
This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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.
