# TD Snap® vs Fast AAC

The clearest difference is review sentiment: Fast AAC at 80% against TD Snap®'s 31%. Fast AAC also leads on monetization model (free vs subscription) and update cadence (every 3 days vs every 2 months). TD Snap®'s advantage is ratings volume (877 vs 8) and iOS requirement (13.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. TD Snap® sells 4 in-app purchases, starting at $4.99 per month and Fast AAC sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Fast AAC holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: TD Snap® has 877 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 31% of TD Snap®'s written reviews are positive against 80% of Fast AAC's.

TD Snap® ships an update every 2 months, Fast AAC every 3 days. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
