# Training Today vs CalcuRun

The clearest difference is rating: CalcuRun at 5.0 against Training Today's 4.6. CalcuRun also leads on monetization model (free vs freemium). Training Today's advantage is ratings volume (2.6K vs 6) and iOS requirement (16.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Training Today sells 4 in-app purchases, starting at $2.95 per month and CalcuRun sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CalcuRun holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Training Today has 2.6K ratings behind it against 6, so its average is the more settled of the two.

Training Today ships an update every 6 weeks, CalcuRun every 4 weeks. The most recent releases landed on October 27, 2026 and October 18, 2026 respectively.
