# Sensor Technology Engineering vs Physics Labs

The clearest difference is ads: Sensor Technology Engineering at none against Physics Labs's shown. Sensor Technology Engineering also leads on iOS requirement (13.0 vs 15.6). Physics Labs's advantage is update cadence (every 2 weeks vs every 7 months). On price, 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.

Sensor Technology Engineering ships an update every 7 months, Physics Labs every 2 weeks. The most recent releases landed on November 7, 2026 and November 4, 2026 respectively.
