### 1/5 — Useless

*2026-06-25, version 1.2.8*

Crashes regularly on iOS; completely unintuitive; incomplete information.

### 1/5 — What happened?

*2026-01-26, version 1.2.5*

I’ve been using this app for a couple of years and it’s been great! But as of mid January it no longer shows real time bus movements.

### 1/5 — Will not open

*2025-11-11, version 1.2.0*

I do not recommend, I downloaded while in Greece and it will not open. iPhone 13

### 1/5 — Useless in Athens

*2025-11-04, version 1.2.0*

This app in Athens is just useless. It does not recognize any address even the most popular ones like the airport and the largest Ktel in Kifissiou. The search always ends up in looking in alternative apps to find your way in Athens

### 1/5 — HOPELESS

*2025-09-23, version 1.1.9*

This app unfortunately tries to work but isn’t looked after by its makers to fix bugs etc. don’t produce something that half heartedly doesn’t deserve to be done

### 1/5 — Lots of data, little use

*2025-09-10, version 1.1.9*

For an app that has so much raw information on it, it’s incredibly unhelpful. It doesn’t know many addresses, so it can’t help you choose a route, and it dumps so much information at you that you’ll never find what you need

### 1/5 — Άχρηστη ….

*2025-07-01, version 1.1.9*

Αποφάσισα να πάρω το Χ96 από τα Πηγαδάκια στο Αεροδρόμιο και επιστροφή. Ποτέ δεν πήρα αξιόπιστο δρομολόγιο ή αρλούμπες ή λάθος. Δυστυχώς το επιτοκιακό κράτος δεν μπορεί να έχει μια αξιόπιστη εφαρμογή για να βγάλει τον κόσμο από τα αυτοκίνητα που έχουν κάνει την κίνηση στην Αθήνα απελπιστικά αργή. Ζήτω το Έθνος!

### 1/5 — Problematic and disorganized

*2025-06-06, version 1.1.9*

Desperately needs an update. The app usually bugs out and stops working. Also the User Experience and the flow of understanding the bus routes is unclear. Has potential to be a helpful app but needs work.

### 1/5 — Absolute rubbish

*2025-05-30, version 1.1.9*

Useless app, not even the starting time tables are correct. Total trash

### 1/5 — Nope

*2025-05-14, version 1.1.8*

Update after update says it fixed something but all you get is error and failure. One star is one star to many.
