# Sensorberg One Access vs OneFlash

The clearest difference is rating: Sensorberg One Access at 5.0 against OneFlash's 3.3. OneFlash's advantage is review sentiment (71% vs 33%) and ratings volume (22 vs 1). 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.

Sensorberg One Access holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: OneFlash has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Sensorberg One Access's written reviews are positive against 71% of OneFlash's, so the app with the better star average is not the one people write more warmly about.

Sensorberg One Access ships an update fortnightly, OneFlash every 2 weeks. The most recent releases landed on August 27, 2026 and September 22, 2026 respectively.
