Google Play will give you 48 hours to refund your purchase or I can refund at any time if you send me your purchasing email address. Feel free to purchase the app and then refund it if you wont’ like it. See How can I get a refund?

My PixFolio for iOS app is free for iCloud access and basic slideshows. If you want to connect to other services or change more advanced settings, then you need a subscription or lifetime purchase. The subscription comes with a 7 day trial so you can try out all app features for 7 days before finalizing a purchase.
