# SMART vs RubiMask

SMART and RubiMask 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. SMART sells 10 in-app purchases, starting at $2.99 per month and RubiMask sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

SMART ships an update monthly, RubiMask every 4 weeks. The most recent releases landed on October 5, 2026 and September 30, 2026 respectively.
