# NightEye vs Proteus Sensor Cloud

The clearest difference is rating: Proteus Sensor Cloud at 5.0 against NightEye's 3.2. Proteus Sensor Cloud also leads on update cadence (every 6 weeks vs every 6 months). NightEye's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). 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.

Proteus Sensor Cloud holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: NightEye has 9 ratings behind it against 1, so its average is the more settled of the two.

NightEye ships an update every 6 months, Proteus Sensor Cloud every 6 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
