## What is gravity clock?

Watching the time pass has never been so beautiful!

Gravity Clock visualizes the passage of time by the permanent destruction and reconstruction of the clock-face. 
Every second the hand breaks numbers out of the dial and lets them drop to the floor where they get buried by the following numbers and eventually wither away to make room for the endless succession of time.

### 1/5 — Belle idée, mais impossible à paramétrer

*2025-12-01*

La case destinée à paramétrer est à la place de la case de fermeture de l'écran .. bref disparition quand on veux couper le son , ou paramétrer la gravité.. nul

### 1/5 — Opening settings causes crash

*2025-10-23, version 3.0.1*

Can no longer change settings, app crashes. Please fix, love this app.

### 5/5 — Great way to watch time fall away

*2025-06-23*

Awesome clock app. So cool to adjust gravity and change the flow. Also love how can choose between analog and digital.

### 3/5 — The analogue and digital clocks show different times

*2024-05-25, version 3.0.1*

When I travel abroad the analogue clock continues to show UK time but the digital display shows local time.

### 5/5 — Love it.

*2022-02-20*

This was the first app I downloaded 10+ years ago. I’ve loved it the whole time. It’s been on every device I’ve owned. Can you make a countdown timer like this?

### 5/5 — iOS14.2 iPhone xs 落ちる

*2020-11-19*

iOS13.7 からアップデートしたら、App を起動して即落ちるようになりました。残念！アプデお願いします。

### 5/5 — ⭐️⭐️⭐️⭐️⭐️

*2020-06-13*

Perfect app, but I would like it to do Arabic-Indic numerals (١٢٣٤٥٦٧٨٩٠).

### 3/5 — Update

*2019-06-26*

Love the app it could stand to updated when open it does not open

### 3/5 — Gravity clock

*2018-05-07*

Muito bom, mas sinto falta da área do texto. E poderia ter acesso ao calendário do celular.

### 3/5 — Where's the Alarm?

*2017-08-20*

I rated this 5 stars when I got this a few years ago.  It continued to be 5 stars until the latest update.  Now, I can't find the alarm function.  My workaround is to use the alarm in the native clock app on my iPad but still have Gravity Clock displayed.  Please restore the alarm function in Gravity Clock and my rating will jump to 6 stars!
