### 4/5 — Crashes

*2011-02-09*

I love the app but it crashes every second time I turn it on
I have no idea why but please fix this

### 5/5 — Great

*2009-09-12*

This is the best app ever.  Only bad thing is that it does the dots.  If possible make it do 1's and 0's. I understand if there isnt room on the screen but please try.

### 1/5 — Was cute at one time

*2022-05-28*

Now when you open it you get a full page pop up after less than 30 seconds.
Past its prime. 
Taking up space. 
Delete….

### 1/5 — Lame

*2016-10-02*

I downloaded it, and as soon as it shows the time, it crashes and shuts down.

### 1/5 — Good but ...

*2009-09-09*

screen lock doesn't work.
We should be able to see one byte per row regardless of screen orientation

### 3/5 — Fix please

*2015-08-24*

This app is great and looks great but it becomes a hassle when I try to use it by unlocking my phone, searching for the app, and clicking on it. I use it for work and it would be nice if it just showed up on my lock screen. Please fix, would appreciate and give a better rating.

### 3/5 — Good

*2010-01-10*

It's a cool app. I just wish I knew how to read it. I think there should be a section that explains how each number us represented. I kind of starting getting 1-9 but the other numbers were a little harder for me.

### 4/5 — 全面広告が少しウザいです。

*2023-12-05*

音も出るし。上下の帯だけではダメなのかな。

### 4/5 — Clean & Efficient

*2017-05-05*

A well made app that's light weight, clean and does it's job efficiently. Very Nice!!

### 4/5 — Review

*2012-03-01*

Great app

### 4/5 — Good

*2012-02-11*

Having both the 3 rows or the 6 is great and the options are awesome too. The ad at the bottom makes for a very unappealing portrait mode. Otherwise this would be a 5 star app for being free.

### 4/5 — Binary clock has 11 binary columns

*2011-07-25*

Very nicely done

### 5/5 — Fun little app

*2025-04-11*

Downloaded it many years ago and it still works bravo

### 5/5 — Love it!

*2021-06-05*

Easy to download and I find it to be a stable app. Makes me think that little bit harder when looking up the time which is good for my ageing brain.

### 5/5 — 101 stars

*2020-09-21*

### 5/5 — Finally!! A true binary clock!!

*2015-06-14*

I searched for one of these and this is the only one I found.

### 5/5 — Fun app

*2011-08-07*

I'm used to the 4 dot binary clock, but it didn't take me that long to figure out this one. I like it. 

If you don't know how to read binary clocks, google it. You can find instructions online. People should learn to look for instructions on their own. Some folks are waayyy to spoiled about being spoon fed with every information.

### 5/5 — How to read

*2011-06-11*

Portrait (upright) bottom to top: 1, 2, 4, 8, 16, 32. Add the values.
Landscape bottom to top: 1, 2, 4, 8. Notice there are two rows for hours, minutes, & seconds each. Each left row is tens and each right row is ones. Add the values.

### 5/5 — Like it
