### 3/5 — Bússola não funciona mais

*2026-08-08*

A bússola não está funcionando corretamente.

### 4/5 — ISS Détector

*2026-07-07*

Fonctionne très bien , petit bémol , trop grisé à gauche pour la lecture des heures de passage

### 3/5 — Mise à jour décevante

*2026-05-07*

Nouvelle présentation moins facile à utiliser et moins agréable à suivre

### 1/5 — New update unuseful

*2026-04-15*

The newer update makes the app unuseful for Hamradio. Just a trash! Unable to find correct altitude when the antena has any angle (left/right), and just change the view when it is close to 90°. Now I paid for a trash app, that was 100% useful before this update.

**Developer response:** I'm sorry you don't like the update. There is an option in the Settings called 'Auto Stardome switch'. Turn this off to stop switching to the star dome.

### 5/5 — Does what it says.

*2026-04-13*

Exactly. Most user friendly.

### 1/5 — Not Working With My iOS 26.2.1

*2026-02-13, version 2.11.0*

I’ve purchased the Amateur Radio Satellites extension. My app gets completely wiped, no satellites, won’t restore satellites even when I do a “Restore Purchased Extensions”.  If I delete the app and re-download from the App Store everything is there again, but the next day the app is wiped clean again. Can’t find a customer support link. Using an Apple iPhone 15 with iOS 26.2.1.

### 5/5 — App todo em inglês

*2026-01-06*

O aplicativo é todo em inglês. Não existe opção para português no iPhone. Para Android sim. A que diz respeito à funcionalidade se propõe, é excelente.

### 5/5 — The best for amateur radio satellites

*2026-01-04*

This is a great app for anyone wanting to track satellites and the ISS, but it’s especially great for amateur radio. It’s possible to filter the list down to the sats you want to track, and then when a pass is happening you can track it in AR while having the frequency (with Doppler shift calculation!) on a single screen. It’s full featured and very easy to use, plus very affordable with no subscription.

### 5/5 — Intuitive

*2025-10-17, version 2.10.1*

Cool intuitive app ☝️😎

### 5/5 — Please re-add feature

*2025-09-14*

Love the app, it’s fantastic in all ways. One caveat, previously when you clicked on a “sighting” and entered the “radar” mode, if you pressed and held, labels for everything currently in the sky would appear. This stopped happening at some point over the last 2 years. Don’t know exactly when but would love for this feature to be re added. It greatly reduced how much I used this application and the ease of information it provided. None the less, 5 stars great app.
