### 5/5 — Love it!

*2023-03-20*

I pull this bad boy out at least twice a day!! Slowly building a subtle understanding of the chronology of earths history thanks to this app! Love the wheel design as well, you can easy scroll back 50 ka or 4.5 billion years in seconds.

I will learn of an impact, rush to see where it lies in the ICS-Timescale, then see if it lines up with something! Whoooo! Back to google to learn more about a different time period. Day after day, wormhole after wormhole..

The Earth has lots of exciting stories to tell!

ICS-Timescale helps keep them all in order.

### 3/5 — Update for iOS14
