AltitudeAlert, the groundbreaking altitude alerting app takes it to the next level with V3. V3 harnesses the power of your device's barometric sensor (see hardware requirements below), delivering incredibly precise altitude data.

New ALT HOLD Mode is specifically designed for VFR pilots requiring virtually no setup. Just tap the button and AltitudeAlert will monitor your current altitude. This mode is great for student pilots, formation flying, and pilots of vintage, ultralight, and light sport aircraft with minimal instrumentation.

Apple Watch Integration! V3 now adds haptic feedback to its alerting engine (requires iPhone).

Never miss an altitude assignment again. In SELECTOR Mode, Set the altitude and V3 alerts you prior to reaching it and again when you acquire it. Spoken alert announcements are customizable. Choose from a single chime or chime plus altitude remaining to selected altitude.

Need to shoot an approach? No problem! In SELECTOR Mode, set the minimums and V3 will alert you 100' above minimums and again at minimums.**

**Barometric sensor required (see SYSTEM REQUIREMENTS below).


• iPad version runs along side or in the background while using your favorite EFB App, i.e. Foreflight, Garmin Pilot, FlyQEFB, etc.

• Alerting for supplemental oxygen use for both pilot and passengers.

• Instrument Approach Minimums Alerting.**

**Barometric sensor required (see SYSTEM REQUIREMENTS below).
