# Engage SSF vs Sunrun

The clearest difference is ratings volume: Sunrun at 3.4K against Engage SSF's 72. Sunrun also leads on update cadence (every 4 weeks vs every 3 months) and device support (3 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.6 for Engage SSF against 4.5 for Sunrun. That said, the two scores are not equally well evidenced: Sunrun has 3.4K ratings behind it against 72, so its average is the more settled of the two.
