# iFIT Personal Trainer vs Specimen

The clearest difference is ads: iFIT Personal Trainer at none against Specimen's shown. iFIT Personal Trainer also leads on ratings volume (1.4K vs 1) and chart position (#138 vs unranked). Specimen's advantage is rating (5.0 vs 4.7). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. iFIT Personal Trainer sells 2 in-app purchases, starting at $19.99 per month and Specimen sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Specimen holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: iFIT Personal Trainer has 1.4K ratings behind it against 1, so its average is the more settled of the two.

iFIT Personal Trainer ships an update fortnightly, Specimen every 9 days. The most recent releases landed on October 18, 2026 and October 3, 2026 respectively.
