# ONE vs StarTrack

The clearest difference is ads: StarTrack at none against ONE's shown. ONE's advantage is iOS requirement (15.1 vs 17.6). On price, in-app purchases and device support there is nothing between them.

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