# Decoded vs Assumptions

The clearest difference is ads: Decoded at none against Assumptions's shown. Assumptions's advantage is update cadence (every 2 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Decoded sells 5 in-app purchases, starting at $4.99 per 7 days and Assumptions sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Decoded ships an update every 3 weeks, Assumptions every 2 days. Both last shipped on November 5, 2026.
