Absolute Stability – 0% Crashes throughout the entire summer

Throughout the entire summer, Vario One recorded not a single crash – neither on iPhone nor on Apple Watch. The crash rate stands at exactly 0 percent.

For an app used while flying, stability is not an optional feature – it is a basic requirement.

Why stability is the highest priority

An app crash during flight can mean:

No Variometer – you lose your most important instrument for thermal flying
No flight recording – your flight is not saved
No acoustic feedback – you fly without the usual tones
Distraction – instead of flying, you’re trying to restart the app

That’s why at Vario One, quality consistently takes precedence over new features. Every update is only released when stability has been demonstrably ensured.

Tested under real conditions

This result is no coincidence. Vario One is extensively tested by experienced paraglider pilots and software developers:

Under real flight conditions – not just in the lab
In various weather conditions – thermals, wind, turbulence
On different devices – iPhone and Apple Watch, various models
Over long flight durations – including multi-hour flights

Thanks to the development team

A big thank you to the entire development team that puts quality over speed. Stability isn’t glamorous, but it is the foundation on which everything else is built.
