# Premom vs Fastastic

The clearest difference is update cadence: Fastastic at daily against Premom's weekly. Premom's advantage is chart position (#39 vs unranked) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Premom sells 12 in-app purchases, starting at $9.99 per month and Fastastic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Premom ships an update weekly, Fastastic daily. The most recent releases landed on November 2, 2026 and October 28, 2026 respectively.
