This is a paid app, be careful. – Body Tune - Photo Editor Review

Once you download, you will be informed that this is a paid subscription and you have 3 days before you are charged $29.99. That’s 3 days in which to find the subscription on your device to cancel before you are charged. And since you have been put into a 3 day trial period, that subscription isn’t listed yet, so there’s no way to cancel it from your device. I’ve contacted support to cancel and will update review accordingly.
