# FORM Swim vs T

The clearest difference is review sentiment: T at 100% against FORM Swim's 53%. T also leads on in-app purchases (none vs 5) and rating (5.0 vs 4.7). FORM Swim's advantage is ads (none vs shown) and ratings volume (3.5K vs 2). On price and update cadence there is nothing between them.

Both are free to download. FORM Swim sells 3 in-app purchases, starting at $14.99 per month. T asks for nothing beyond the download.

T holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: FORM Swim has 3.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 53% of FORM Swim's written reviews are positive against 100% of T's.

FORM Swim ships an update every 2 weeks, T every 3 weeks. The most recent releases landed on October 20, 2026 and October 2, 2026 respectively.
