# 23 Equations vs Physics Master Homework Tutor The clearest difference is rating: 23 Equations at 5.0 against Physics Master Homework Tutor's 4.4. 23 Equations also leads on ads (none vs shown) and iOS requirement (9.3 vs 15.5). Physics Master Homework Tutor's advantage is ratings volume (136 vs 1) and review sentiment (65% vs 48%). On price, update cadence, in-app purchases and monetization model there is nothing between them. Both are free to download. 23 Equations sells 7 one-off in-app purchases and Physics Master Homework Tutor sells 13 in-app purchases, starting at $3.49 per month. Whichever you choose, the download price is not the number that matters. 23 Equations holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Physics Master Homework Tutor has 136 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 48% of 23 Equations's written reviews are positive against 65% of Physics Master Homework Tutor's, so the app with the better star average is not the one people write more warmly about. 23 Equations ships an update every 2 weeks, Physics Master Homework Tutor every 4 weeks. The most recent releases landed on September 26, 2026 and October 5, 2026 respectively. ## The numbers | Metric | 23 Equations | Physics Master Homework Tutor | | --- | --- | --- | | Price | Free | Free | | Rating | **[5.0 (1 ratings)](https://appshunter.io/ios/app/23-equations/id1451090127/reviews)** | [4.4 (136 ratings)](https://appshunter.io/ios/app/physics-master-homework-tutor/id1453430489/reviews) | | Number of ratings | 1 | **136** | | Positive reviews | 47.6% of reviews | **64.7% of reviews** | | In-app purchases | Yes | Yes | | Ads | **No** | Yes | | Update frequency | **Every 2 weeks** | Every 4 weeks | | Monetization | Free with in-app purchases | Free with in-app purchases | | Size | 143 MB | 117 MB | | Requires iOS | **9.3** | 15.5 | | Devices | iPhone, iPad, iPod | iPhone, iPad, iPod | | Age rating | 4+ | 4+ | | Developer | [Nick Whitehurst](https://appshunter.io/developer/1451090126) | [Carlo Terracciano](https://appshunter.io/developer/1159639539) | ## What reviewers say ### 23 Equations [App page](https://appshunter.io/ios/app/23-equations/id1451090127) Master GCSE and IGCSE Physics equations with interactive learning and practice questions.
