# Fluxmeter vs Physics Labs

The clearest difference is ads: Fluxmeter at none against Physics Labs's shown. Fluxmeter also leads on monetization model (free vs ad-supported). On price, review sentiment, update cadence 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.

Fluxmeter ships an update fortnightly, Physics Labs every 2 weeks. The most recent releases landed on September 27, 2026 and September 18, 2026 respectively.
