# UI HandBook vs DevTutor

UI HandBook and DevTutor 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. UI HandBook sells 1 one-off in-app purchase and DevTutor sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

UI HandBook ships an update monthly, DevTutor every 2 weeks. The most recent releases landed on September 19, 2026 and September 15, 2026 respectively.
