You can now access TreeRing using mobile devices. You should use Google Chrome browser on your mobile device for the best functionality. You can upload photos and place orders. Custom pages cannot be done on a mobile device.
We still have our iOS app for iPhones. You can upload photos, create custom pages, and place orders. iPhone users should use the iPhone app. This will eliminate the HEIC issue with uploading photos. (If you have that setting turned on to save space on your phone.)
