# Systems vs Dumai

The clearest difference is monetization model: Dumai at free with in-app purchases against Systems's subscription. Dumai also leads on update cadence (weekly vs every 4 weeks) and iOS requirement (15.1 vs 26.0). Systems's advantage is ads (none vs shown). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Systems sells 4 in-app purchases, starting at $3.99 per 7 days and Dumai sells 9 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Systems ships an update every 4 weeks, Dumai weekly. Both last shipped on October 30, 2026.
