Carmona OS is built for lifters who want a real program and a better answer to one recurring question: what should I do next? Choose Precision or Essentials, then train the full session or switch to 45 Min when time is tight. • Precision is a five-day, pre-fatigue split for experienced lifters. • Essentials is a push, pull, legs foundation you can run two to six days a week. Past three days, repeat sessions shift their emphasis instead of repeating the same workout. Each session gives you the exercises, sets, reps, rest, and starting weights. As you train, Carmona OS learns from what you actually complete and helps you find the right next weight. Progress is earned through consistent, controlled work. A strong session can lead to an increase. A near miss can hold the weight so you can try again. If a load is clearly too heavy, or your effort answer suggests it may not be safe, the app asks you to reassess instead of giving you a recommendation it cannot defend. In 45 Min, the exercises you complete still count and the ones you do not reach are not held against you. You can also swap an exercise, pause and resume, or finish early without losing the work you completed. After each workout, your receipt explains what happened and what comes next. The Engine gives you a clear view of where you are progressing and where the app is still learning. Nutrition guidance adds daily targets and practical playbooks for eating out, lunch, and cooking at home. Carmona OS is free to download and includes your first six workouts. Continuing with Workout 7 and future training requires Carmona OS Premium, available as a monthly or annual auto-renewing subscription. Subscription terms and pricing are shown before purchase.

Verdict
The clearest difference is monetization model: Carmona OS at freemium against Strongsplit's subscription. Carmona OS also leads on update cadence (every 2 days vs fortnightly) and iOS requirement (15.0 vs 17.0). Strongsplit's advantage is ratings volume (78 vs 5) and rating (4.4 vs 4.2). On price, review sentiment, ads and in-app purchases 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. Strongsplit sells 2 in-app purchases, starting at $3.99 per month and Carmona OS sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
Strongsplit holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Strongsplit has 78 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 54% of Strongsplit's written reviews are positive against 50% of Carmona OS's.
Strongsplit ships an update fortnightly, Carmona OS every 2 days. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
