# InnerBase AI vs Whenly

InnerBase AI and Whenly are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. InnerBase AI sells 1 one-off in-app purchase and Whenly sells 3 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

InnerBase AI ships an update weekly, Whenly fortnightly. The most recent releases landed on November 5, 2026 and November 2, 2026 respectively.
