### 5/5 — Excellent

*2025-07-19, version 1.0.6*

We use this on our phones whenever we are travelling without our gro clock.

### 5/5 — Amazing way better than the gro clock

*2023-03-20, version 1.0.5*

My toddler loves the sun so much! This app is light years better than the old school “groclock.” Super responsive developer and amazing app. They even implemented one of my suggestions in the latest update.

Update on my review. Developer is amazing and even incorporated some enhancements requests.
