# Power Sensor vs Red

The clearest difference is rating: Red at 5.0 against Power Sensor's 2.6. Power Sensor's advantage is monetization model (free vs ad-supported) and ratings volume (14 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Red holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: Power Sensor has 14 ratings behind it against 2, so its average is the more settled of the two.

Power Sensor ships an update every 3 weeks, Red monthly. Both last shipped on October 24, 2026.
