AB Quantum Erfahrungen und Bewertung

Unstable

The ballistics part of this app is great. There are many settings and if you know what to enter you get a very accurate and result. But the app part, as in user experience and stability is very poor. The content is zoomed, fixed in a static ratio and therefore boxed in a black border on modern phones. It looks like a museum exhibit. In light theme, the graph view has black text on black background, which makes it unusable. Whenever you click on a field, the keyboard resets (disappears and pops up immediately) and the cursor gets placed at the end. No chance to put the cursor somewhere in the middle to correct the value. Another great bug is the look angle. You can let the app measure the angle from the phone. The value is displayed with 3 decimal places, but is then put into the field without the decimal separator making it invalid. Because of the previously mentioned bug, it impossible to insert the separator without deleting the decimal numbers.

If you know what you are doing and feed the app with correct boundary conditions, you’ll receive extremely accurate solutions. I use it in combination with my WeatherFlow to determine the environmental conditions and MagnetoSpeed to measure the muzzle velocity of my cartridges. So far I was able to test the calculations with custom drag models to distances of up to 800m without noticeable deviations. In my opinion the best stand alone solution available for mobile devices.
