# StrengthIn vs PRO

The clearest difference is rating: StrengthIn at 5.0 against PRO's 3.9. StrengthIn also leads on update cadence (every 3 weeks vs every 15 months). PRO's advantage is in-app purchases (none vs 3) and ratings volume (8 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. StrengthIn sells 3 one-off in-app purchases. PRO asks for nothing beyond the download.

StrengthIn holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: PRO has 8 ratings behind it against 1, so its average is the more settled of the two.

StrengthIn ships an update every 3 weeks, PRO every 15 months. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
