# Fortify AI vs Pack

The clearest difference is in-app purchases: Pack at none against Fortify AI's 10. Fortify AI's advantage is ratings volume (118 vs 1) and update cadence (every 2 weeks vs every 4 weeks). On price, rating, ads and device support there is nothing between them.

Both are free to download. Fortify AI sells 10 in-app purchases, starting at $9.99 per month. Pack asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Fortify AI against 5.0 for Pack. That said, the two scores are not equally well evidenced: Fortify AI has 118 ratings behind it against 1, so its average is the more settled of the two.

Fortify AI ships an update every 2 weeks, Pack every 4 weeks. Both last shipped on October 31, 2026.
