# Belimo RetroFIT+ vs Olight

The clearest difference is rating: Belimo RetroFIT+ at 5.0 against Olight's 4.0. Belimo RetroFIT+ also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Olight's advantage is update cadence (fortnightly vs every 7 months) and ratings volume (79 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Belimo RetroFIT+ holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Olight has 79 ratings behind it against 1, so its average is the more settled of the two.

Belimo RetroFIT+ ships an update every 7 months, Olight fortnightly. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
