# Rubicon vs MultipliKid

The clearest difference is ads: MultipliKid at none against Rubicon's shown. Rubicon's advantage is update cadence (every 2 days vs monthly) and iOS requirement (13.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Rubicon sells 7 one-off in-app purchases and MultipliKid sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Rubicon ships an update every 2 days, MultipliKid monthly. The most recent releases landed on October 4, 2026 and October 7, 2026 respectively.
