# Nimble vs Go Green OS

The clearest difference is rating: Go Green OS at 5.0 against Nimble's 4.5. Go Green OS also leads on monetization model (free vs freemium) and update cadence (every 5 days vs every 4 weeks). Nimble's advantage is ratings volume (620 vs 1) and iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

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

Go Green OS holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Nimble has 620 ratings behind it against 1, so its average is the more settled of the two.

Nimble ships an update every 4 weeks, Go Green OS every 5 days. Both last shipped on November 6, 2026.
