# Russian vs Intervalia

The clearest difference is ads: Intervalia at none against Russian's shown. Intervalia also leads on update cadence (every 3 days vs every 9 days). Russian's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Russian sells 3 one-off in-app purchases and Intervalia sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Russian ships an update every 9 days, Intervalia every 3 days. Both last shipped on October 25, 2026.
