# Premom vs ASPIRE Study

The clearest difference is in-app purchases: ASPIRE Study at none against Premom's 16. Premom's advantage is update cadence (weekly vs monthly) and chart position (#35 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Premom sells 12 in-app purchases, starting at $9.99 per month. ASPIRE Study asks for nothing beyond the download.

Premom ships an update weekly, ASPIRE Study monthly. The most recent releases landed on October 21, 2026 and October 13, 2026 respectively.
