### 4/5 — Complaint

*2026-02-08, version 1.2.6*

On setting number 3, there was a view of something that featureless now.

### 5/5 — Bigbinaryclock is a nice app but there is a misspelling for show time

*2023-10-07*

Nice clock everything is free and awesome and it’s pretty cool and it’s just a nice clock and it’s got a misspelling for the settings and It’s Show not Schow it’s not a word but show is so fix the spelling please thanks

### 3/5 — Can’t change display color.

*2022-06-28*

The description shows 3 color choices blue, red green. The app does not give the option to change/set the color??

Otherwise it is exactly what I want. With the cute typo:’schow’

**Developer response:** Swipe right, left to change color

### 3/5 — Ganz nett

*2021-06-19*

Ich finde die Idee einer binären Uhr extrem gut, leider fehlt die Widget Umsetzung, das heißt um die binäre Uhrzeit zu sehen muss die App geöffnet werden. Hatte ich so nicht erwartet, schade um die 0,49 Cent. Ich hoffe die Widget Option wird nachgebessert, dann gibt es direkt 5 Sterne …

### 3/5 — Puzzled

*2016-01-15*

00h midnight shows in binary as 31 Dec ??

### 5/5 — Great Digital Clock App

*2015-01-31*

Great digital clock display, easy to read, and nice features.
