Progressive overload shouldn’t be guesswork. Most lifters understand the principle: lift more over time. But when it comes to execution, it gets confusing. Should you increase weight and drop reps? Add reps at the same weight? How do you know what actually pushes adaptation without stalling? I built this app because I was tired of bouncing between e1RM calculator websites before and after workouts. I’d plug in numbers, test a weight, adjust the next session, and repeat through trial and error. It broke focus and slowed progress. This app removes that friction. It automatically calculates your estimated one-rep max (e1RM) and helps guide intelligent progression. Instead of guessing what to lift next, you get structured guidance based on your performance. No spreadsheets. No switching between calculator tabs. No random weight jumps. Just clear, data-driven progression. What it does: • Calculates and tracks your estimated 1RM • Helps determine when to increase weight vs. reps • Encourages consistent progressive overload • Keeps your progression structured and measurable If you’re serious about getting stronger, this turns progressive overload from theory into a system. Train with intention. Progress with clarity.

Verdict
The clearest difference is in-app purchases: Progressive Overload at none against JuggernautAI's 2. JuggernautAI's advantage is rating (4.8 vs 4.4) and ratings volume (5.7K vs 7). On price, review sentiment, update cadence and ads 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. JuggernautAI sells 1 in-app purchase, starting at $34.99 per month. Progressive Overload asks for nothing beyond the download.
JuggernautAI holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: JuggernautAI has 5.7K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 73% of JuggernautAI's written reviews are positive against 67% of Progressive Overload's.
Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
