### 5/5 — The best vintage military clock app out there

*2021-11-09, version 1.2.1*

Bar none, this is the best military clock app out there. All of the miliary clocks by this developer are… However, there are two things i wish.. while you can turn off location features (The digital location/gps feature) it still leaves the bright numbers on the clock which are extremely distracting and take away from the vintage beauty of the clock. Secondly. I am begging.. on my hands and knees.. that the developer make an app for the 1942 black dial Hamilton GCT (the military pocket watch used by bomber crews and others during wwii… again.. please leave off the digital location features). There was an app which had done this one in the past (way back when iphones first came out). But nobody has done it since. And it is the most sought out pocket watch/clock out there). It’s the only one that people actually mention wishing there was an app for. Thanks. Love the app. Please keep updating and making it available for future iphone/ipad applications.

**Developer response:** Dear Adventurewriter, Thank you so much for your glowing words and I am very pleased that you are enjoying the clock. I will look into your suggestions on a future version. - JG
