# Mystery Files vs Inferra

The clearest difference is ads: Inferra at none against Mystery Files's shown. Inferra also leads on update cadence (every 6 days vs fortnightly). Mystery Files's advantage is chart position (#174 vs unranked) and iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Mystery Files sells 10 one-off in-app purchases and Inferra sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mystery Files ships an update fortnightly, Inferra every 6 days. The most recent releases landed on November 13, 2026 and November 10, 2026 respectively.
