# CountX vs Aevum

The clearest difference is ads: Aevum at none against CountX's shown. Aevum also leads on update cadence (fortnightly vs every 10 months). CountX's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. CountX sells 2 in-app purchases, starting at $4.99 per month and Aevum sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CountX ships an update every 10 months, Aevum fortnightly. The most recent releases landed on November 10, 2026 and November 9, 2026 respectively.
