### 5/5 — Fabinacci clock

*2021-02-12, version 1.01*

Brilliant. Perfect timepiece if you only want accuracy to within five minutes and are prepared to take a couple of minutes to read it. I would have liked a reminder about how to tell the time on this clock. I had to do an internet search for instructions.

### 4/5 — Widget

*2020-12-26*

That’s good,
Please add widget for that.
Thank you

### 5/5 — Simple but works

*2019-05-31, version 1.01*

Works on my iPad IOS 12.1.4.
Tap to display colours decode and maths for current time.
Swipe up for options to update faster than 5 minutes, which then goes through the redundant colour combinations.
Geeky but effective. Full screen in portrait mode. Lock the screen there to get full screen landscape.

### 4/5 — Worth 5 Stars If It Had A Landscape Mode Option

*2016-05-16*

I have a fibonacci clock at home and was very pleased to find an identical version in an app.  A little disappointed that it only displays vertically (that is, having its short side as its base) even when my iPad is in landscape mode.

### 1/5 — iOS 9.3

*2016-04-07, version 1.01*

Doesn't work with the above iOS on mini iPad. Great shame as I have a need for it.

### 1/5 — Crashes every time

*2015-12-21*

Just downloaded the app and was looking forward to it. Unfortunately it crashes on start up every single time.

### 5/5 — Awesome Super Nerd App!

*2015-09-19*

I love this super nerdy app!  The clock is good to five minutes. And promptly changes at five minute intervals. I think Ben Franklin would have enjoyed this too.
