Glider Polar vs Flight Display
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Glider Polar
This app predicts glider performance by allowing users to adjust gross weight and headwind. Experienced pilots can explore the impact of water ballast on glide ratio and speed, while beginners can visualize how wind and weight affect performance.
- Predicts glider glide performance
- Adjustable gross weight
- Adjustable headwind component
- Shows effect of water ballast
- Illustrates wind and weight impact

Glider Polar predicts the glide performance of any glider. The user can vary the glider's gross weight and headwind component and immediately see the effect on glider performance. Experienced pilots can use the app to see how water ballast affects the glide ratio and cruise speed. For those new to gliding, the app clearly illustrates the effect of wind and weight on performance.
Flight Display

The Flight Display provides you with main flight instruments in digital format. Your iPhone or Cellular iPad already has all required sensors inside – just install the app and it is ready for flight. The Flight Display’s fusion algorithms use internal device GNSS module and sensors (gyroscope, accelerometer and magnetometer) to calculate all parameters. NOTE: Device internal GNSS module does not provide required stability and precision? Just connect an external GNSS sensor (receiver) to your device and it is ready for more! The Flight Display app is simple and flexible, offering you to: - Create multiple profiles for different aircrafts or conditions. One profile – one unique set of settings; - Setup units and ranges of displayed parameters. Enable alarms for parameters and adjust alarm intervals; - Customize appearance of indicators; - Select portrait or landscape interface orientation; - Mount the device in any position inside the cabin – the app is smart enough to perform correct calculation of attitude and all other parameters even if the device axes are not aligned with the aircraft axes. Just run app’s built-in device orientation adjustment mode and fix the device in any convenient position. List of indicators: - Primary Display indicator; - Ground speed indicator; - Altitude indicator; - Heading indicator; - Turn coordinator/Turn indicator; - Chronometer (with multiple time display modes); - Flight info indicator; - GNSS info indicator; - Device status info indicator; - Destination point info indicator. Result fusion parameters / calculated parameters: - Heading (based on GNSS course/magnetic heading/true magnetic heading); - Ground speed; - Altitude; - Attitude angles (pitch and roll); - Coordinates; - Heading rate; - Flight parameters (time, passed distance, average speed, distance to start point); - Destination point parameters (distance, azimuth, course, reach time).

Verdict
The clearest difference is price: Glider Polar at $2.99 against Flight Display's $12.99. On ads, in-app purchases, device support and iOS requirement there is nothing between them.
