### 4/5 — iOS16.6.1で接続不可

*2023-09-29, version 1.2.8*

iOS16.6.1のiPhone13ProMaxでは、「Bluetooth_ready」表示のままでTC66Cと通信出来ません。
iOS16.2のiPhoneXsでは問題なく通信出来ます。

### 1/5 — Doesn’t work.

*2023-06-18, version 1.2.8*

Does not work on the UD18_BLE.

### 4/5 — Displays Mini Meter Data

*2022-12-11, version 1.2.8*

Does what it should, display tiny screens from micro meter onto phone. Limited functionality.. does what the meter does. Today’s bugs, the languages screen washes out white on iphone 12 up to date. So if you happen to change language theres no way to restore w/o deleting and reinstalling app. Serial number displayed and usage counter displayed are both Chinese headers, please make those language of choice. Love the flip screen button!! Keep up the dev :-)

### 3/5 — Needs Updating

*2022-11-18, version 1.2.8*

Needs updating to the latest IOS and iPhone 14

### 1/5 — App does not work at all

*2022-07-08, version 1.2.7*

Waste of sending money on a product that doesn’t even work!!!!!

### 5/5 — 很方便！

*2022-06-06, version 1.2.7*

剛開始不能連接到藍牙，後來發現原來App裡面就有內建了藍牙連接的功能，可以遠端設定還蠻不錯的！

### 2/5 — Rudimentär

*2022-03-31, version 1.2.7*

Die App erfüllt die Basics. Mann kann die aktuellen Messungen gut ablesen. Die Grafik ist eigentlich ganz schön, aber die automatische Skalierung ist mal richtig mal falsch.

Der Export als Tabelle zu Numbers hat auf Anhieb gut funktioniert.

Die Bluetooth Verbindung ist sehr schwach. Wenn sie abbricht, friert alles ein und wenn es wieder ginge wird das nicht automatisch erkannt. Mann muss sie manuell wieder Verbinden.

Die Liste der Bluetooth Geräte zeigt alles in der Nähe an. Die app filtert nicht nach den relevanten Geräten.

Man hat 3 Tasten in der App. Die eine dreht die Anzeige auf dem USB Tester. Die anderen 2 bewirken das gleiche wie das kurze Drücken auf K1 und K2. Das finde ich sehr nützlich, weil die HW ziemlich klein und zerbrechlich scheint.

Die Übersetzung ist nicht vollständig, aber man kann damit leben.

Alles in allem, kein wow Erlebnis aber brauchbar.

### 2/5 — So buggy

*2022-02-26*

Totally unreliable and buggy. I just use the micro USB connection.

### 4/5 — 概ね良好

*2021-10-25, version 1.2.7*

On IOS15, the app may fail to launch. Also, sometimes the numbers get smaller. It would be perfect if you could do an update to fix these issues.

### 1/5 — Shows inane ad at startup; marginally working

*2021-04-28, version 1.2.7*

This was a basic, but useful app. Now it shows a slash screen that may or may not go away after 5-10 sec. Then shows an ad for something, with countdown time on upper right. Then finally it works on iPhone 11 Pro. 
A useful app ruined.
