# Training Stack vs Incredible

The clearest difference is update cadence: Incredible at every 10 days against Training Stack's every 3 months. Incredible also leads on monetization model (free vs freemium) and ratings volume (68 vs 4). Training Stack's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Training Stack sells 3 in-app purchases, starting at $4.99 per month and Incredible sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Training Stack holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Incredible has 68 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Training Stack's written reviews are positive against 95% of Incredible's.

Training Stack ships an update every 3 months, Incredible every 10 days. The most recent releases landed on October 8, 2026 and October 19, 2026 respectively.
