# DuoSmart vs QSR

The clearest difference is ads: DuoSmart at none against QSR's shown. QSR's advantage is update cadence (fortnightly vs every 9 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

DuoSmart ships an update every 9 months, QSR fortnightly. The most recent releases landed on October 6, 2026 and October 2, 2026 respectively.
