# LeanFITT™ Pro vs LSSI

The clearest difference is in-app purchases: LeanFITT™ Pro at none against LSSI's 10. LeanFITT™ Pro also leads on ratings volume (8 vs 1) and iOS requirement (13.0 vs 15.5). LSSI's advantage is update cadence (fortnightly vs every 18 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. LSSI sells 8 in-app purchases, starting at $9.99 per month. LeanFITT™ Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for LeanFITT™ Pro against 5.0 for LSSI. That said, the two scores are not equally well evidenced: LeanFITT™ Pro has 8 ratings behind it against 1, so its average is the more settled of the two.

LeanFITT™ Pro ships an update every 18 months, LSSI fortnightly. The most recent releases landed on September 23, 2026 and September 17, 2026 respectively.
