# Swing Catalyst vs Swing Index

The clearest difference is review sentiment: Swing Index at 90% against Swing Catalyst's 21%. Swing Index also leads on rating (4.8 vs 3.8) and ratings volume (484 vs 12). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Swing Catalyst sells 23 one-off in-app purchases and Swing Index sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Swing Index holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Swing Index has 484 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 21% of Swing Catalyst's written reviews are positive against 90% of Swing Index's.

Swing Catalyst ships an update monthly, Swing Index every 3 weeks. The most recent releases landed on July 7, 2026 and September 8, 2026 respectively.
