# Window vs Taper Swim

The clearest difference is monetization model: Window at free against Taper Swim's subscription. Taper Swim's advantage is ratings volume (7 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Window sells 1 one-off in-app purchase and Taper Swim sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Window against 5.0 for Taper Swim. That said, the two scores are not equally well evidenced: Taper Swim has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Window ships an update every 9 days, Taper Swim every 8 days. The most recent releases landed on October 13, 2026 and October 6, 2026 respectively.
