### 2/5 — Baro feature broken

*2026-03-24, version 2.6*

Apple Watch series 11, latest iOS, gets stuck on calibrating to local elevation. I got this app for that feature many years ago.

### 1/5 — begs for reviews

*2026-02-18, version 2.6*

unfortunately the app begs for reviews.  its a great tool… but because it does this, it gets only one star. thats policy.

### 2/5 — Doesn’t work on Apple Watch

*2025-10-20, version 2.6*

Barometer calibration doesn’t work on Apple Watch. There are also typos in the UI. Not worth $0.99.

*2025-06-07*

Bien, mais possible d’imaginer une intégration sous CarPlay ?

### 5/5 — Hiking and way finding

*2025-05-23*

I have used this program with maps teaching my kids how to not get lost and just to verify the height of a road or on a ski mountain. Thrilled to have it. Thank you.

### 4/5 — A best travel feature.

*2025-04-23, version 2.6*

A family member has a heart/lung issue that affects the ability to survive elevation above 3,000’ over night while sleeping. 
I use this for determining camping elevations. 👍
