# Task Flow vs Estratum

Task Flow and Estratum 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. Task Flow sells 3 in-app purchases, starting at $1.99 per month and Estratum sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Task Flow ships an update weekly, Estratum every 10 days. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
