# App vs SAIS

The clearest difference is update cadence: App at every 3 weeks against SAIS's every 13 months. SAIS's advantage is iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

App ships an update every 3 weeks, SAIS every 13 months. Both last shipped on November 3, 2026.
