# StackFlow vs AIDO

The clearest difference is update cadence: StackFlow at every 2 weeks against AIDO's every 4 weeks. AIDO's advantage is iOS requirement (15.5 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. StackFlow sells 2 in-app purchases, starting at $4.99 per month and AIDO sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

StackFlow ships an update every 2 weeks, AIDO every 4 weeks. The most recent releases landed on October 19, 2026 and October 31, 2026 respectively.
