### 1/5 — Funktioniert immer noch nicht

*2025-07-22, version 2.4.2*

Es hat man eine Zeit lang funktioniert. Nun läuft es schon seit einer Woche nicht mehr. Einfach unzuverlässig, die Windows Version läuft allerdings ohne Probleme. Auf einem iPhone sollte man sich nach andern Herstellern umsehen.

### 1/5 — Nicht nutzbar unter iOS 15

*2021-10-08, version 2.0.2*

Seit update auf iOS 15 sagt die App, dass mein Gerät nicht mit dem Internet verbunden sei. Somit nicht nutzbar.

### 2/5 — Viel Luft nach oben

*2020-12-10, version 2.0.2*

Manchmal kann keine VPN Verbindung aufgebaut werden. Es werden mehrere Versuche benötigt und App muss komplett geschlossen werden. Habe auch öfter das Problem das sie sich nicht mehr öffnen lässt und beim starten schon abstürzt. iós 14.2

### 2/5 — List of locks is out of order

*2020-10-21*

The app has been pretty solid for me, but I have a bunch of locks and they aren’t in any order at all. The text size is too large so only part of the name is displayed, making it really hard to find the lock I want. The search function is ok, but not ideal. Please fix the ordering issue, and show more of the name of each lock. 

I will change my rating when the locks are sorted alphabetically by name.

### 5/5 — Excellent and easy!

*2019-02-01*

Excellent solution for creating a secure connection to the Tosibox hardware without having to know anything about VPN technology nor connectivity!
