# RealmStep vs Diffu

RealmStep and Diffu 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. RealmStep sells 9 in-app purchases, starting at $1.99 per month and Diffu sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 weeks. Both last shipped on October 24, 2026.
