# Time vs On

The clearest difference is rating: On at 5.0 against Time's 3.0. On also leads on ads (none vs shown). On price, review sentiment, ratings volume 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.

On holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
