# Notice Yourself vs Clarity

Notice Yourself and Clarity 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. Notice Yourself sells 3 in-app purchases, starting at $2.99 per month and Clarity sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Notice Yourself ships an update fortnightly, Clarity every 2 weeks. The most recent releases landed on September 7, 2026 and September 11, 2026 respectively.
