# AIDA vs Scanner App

The clearest difference is iOS requirement: Scanner App at 12.0 against AIDA's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AIDA sells 4 in-app purchases, starting at $4.99 per 7 days and Scanner App sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

AIDA ships an update monthly, Scanner App fortnightly. The most recent releases landed on October 30, 2026 and October 6, 2026 respectively.
