Verdict
The clearest difference is in-app purchases: Problem solver at none against My Physics Calculator lite's 1. Problem solver also leads on iOS requirement (8.0 vs 16.6). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. My Physics Calculator lite sells 1 one-off in-app purchase. Problem solver asks for nothing beyond the download.
Both ship on a similar rhythm, roughly every 6 months. The most recent releases landed on May 16, 2026 and August 15, 2026 respectively.
