Verdict
The clearest difference is ads: MyLineD at none against One Rep Max's shown. MyLineD also leads on review sentiment (67% vs 57%). One Rep Max's advantage is rating (4.4 vs 3.9) and update cadence (every 6 days vs every 6 weeks). On price, in-app purchases, monetization model 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. One Rep Max sells 2 in-app purchases, starting at $2.99 per month and MyLineD sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
One Rep Max holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: One Rep Max has 186 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 57% of One Rep Max's written reviews are positive against 67% of MyLineD's, so the app with the better star average is not the one people write more warmly about.
One Rep Max ships an update every 6 days, MyLineD every 6 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
