### 3/5 — Ειδοποιήσεις

*2025-06-07, version 1.0.5*

Βάλτε να έρχονται ειδοποιήσεις δεν έρχονται

### 4/5 — Καλή, αλλά...

*2023-02-01, version 1.0.3*

Πολύ καλή εφαρμογή, αλλά το φίλτρο για την εισαγωγή ημερομηνίας δεν λειτουργεί.
Επίσης, καλή προσθήκη θα ήταν η δυνατότητα για push notifications.

### 5/5 — Τέλεια εφαρμογή

*2022-01-17, version 1.0.3*

Από τις πλέον εύχρηστες και αξιόπιστες
Εφαρμογές ever

### 4/5 — Τέλεια εφαρμογή αλλά θέλει λίγο βελτίωση

*2022-01-09, version 1.0.3*

Η εφαρμογή είναι τέλεια άμεση ενημέρωση . Απλά εκεί που λέει ένιωσα τον σεισμό κάντε το να δουλεύει ποιο σωστά για να ξέρετε και εσείς καλύτερα αφού θέλετε μέχρι που ακούστηκε . Έγινε σεισμός στην Φλώρινα 5,3 τον καταλάβαμε στην Κέρκυρα και ενώ πατάμε να το ένιωσα τον σεισμό λέει ότι είμαστε μακριά, άρα αυτό που νιώσαμε όλοι ήταν άλλος σεισμός ; Μόνο αυτό διορθώστε .

### 3/5 — Απογοητευμένος.

*2021-12-29, version 1.0.3*

Είναι κρίμα μια εφαρμογή από Έλληνες να είναι φτιαγμένη στα αγγλικά το βρίσκω αδικαιολόγητο και ντροπιαστικό.

### 1/5 — Ημαρτον

*2021-12-28, version 1.0.3*

Πόσο δύσκολο είναι να βάλετε τους σωστούς χάρτες από την Google ? Ειλικρινά όμως !!! Έχετε κατασκευάσει μια τόσο όμορφη εφαρμογή και ο χάρτης που απεικονίζει την σεισμική δραστηριότητα είναι για κλάματα... Δεν μπορεί ο χρήστης να κάνει zoom και η ανάλυση είναι οικτρή !!!  Βαθμολογώ με ένα αστέρι διότι το θέμα με τους χάρτες είναι σοβαρό !!!

### 4/5 — Ειδοποιήσεις.

*2021-12-26, version 1.0.3*

Θα ήταν σημαντική βελτίωση η ενημέρωση για τα γεγονότα μέσω ειδοποιήσεων ώστε να μην χρειάζεται συνεχώς να ανοίγεις την εφαρμογή.

### 5/5 — Works great

*2021-12-01, version 1.0.1*

This is a great app for visualization of seismic activity in Greece. Good job NTUA for the development of this!

### 5/5 — Επιτέλους

*2021-11-27, version 1.0.1*

Πραγματικά περιμέναμε τόσο καιρό μια τέτοια εφαρμογή ευχαριστούμε πολύ ελπίζω να μην σταματήσει αυτή η προσπάθεια

### 5/5 — Great app

*2021-11-26, version 1.0.1*

Seems Stable very well designed !
Excellent effort !
