# Plus vs TrailDash

The clearest difference is ads: TrailDash at none against Plus's shown. Plus's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 18.1). On price and in-app purchases there is nothing between them.

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