# magnetoboy vs Physics Labs

The clearest difference is ads: magnetoboy at none against Physics Labs's shown. magnetoboy also leads on monetization model (free vs ad-supported) and iOS requirement (12.0 vs 15.6). Physics Labs's advantage is update cadence (every 2 weeks vs monthly). On price, review sentiment, 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.

magnetoboy ships an update monthly, Physics Labs every 2 weeks. The most recent releases landed on September 9, 2026 and June 9, 2026 respectively.
