# Relentless Trainer vs Warrior Lab

The clearest difference is update cadence: Relentless Trainer at every 5 days against Warrior Lab's fortnightly. Relentless Trainer also leads on ratings volume (15 vs 3). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Relentless Trainer sells 9 in-app purchases, starting at $9.99 per month and Warrior Lab sells 16 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Relentless Trainer against 5.0 for Warrior Lab. That said, the two scores are not equally well evidenced: Relentless Trainer has 15 ratings behind it against 3, so its average is the more settled of the two.

Relentless Trainer ships an update every 5 days, Warrior Lab fortnightly. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
