# Smile vs DIMIR

The clearest difference is ads: Smile at none against DIMIR's shown. DIMIR's advantage is update cadence (every 3 days vs every 3 weeks) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Smile sells 4 in-app purchases, starting at $4.99 per 7 days and DIMIR sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Smile ships an update every 3 weeks, DIMIR every 3 days. Both last shipped on October 31, 2026.
