# Watt vs eCar

The clearest difference is ads: eCar at none against Watt's shown. eCar also leads on iOS requirement (11.0 vs 13.4). 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.
