# Challenges Aid vs Personal Trainer AI

The clearest difference is review sentiment: Personal Trainer AI at 94% against Challenges Aid's 36%. Personal Trainer AI also leads on rating (4.6 vs 4.3) and update cadence (every 6 days vs every 3 weeks). Challenges Aid's advantage is device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Challenges Aid sells 3 in-app purchases, starting at $0.99 per month and Personal Trainer AI sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Personal Trainer AI holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Personal Trainer AI has 106 ratings behind it against 8, so its average is the more settled of the two.
