# Flexi vs LearnWhat

Flexi and LearnWhat 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. Flexi sells 4 in-app purchases, starting at $5.99 per month and LearnWhat sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Flexi ships an update weekly, LearnWhat every 4 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
