# Sensor Data Recorder vs Physics Labs

The clearest difference is review sentiment: Physics Labs at 100% against Sensor Data Recorder's 50%. Physics Labs also leads on update cadence (every 2 weeks vs every 26 months). Sensor Data Recorder's advantage is ads (none vs shown) and monetization model (free vs ad-supported). 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.

Sensor Data Recorder ships an update every 26 months, Physics Labs every 2 weeks. The most recent releases landed on October 5, 2026 and September 18, 2026 respectively.
