Device and app compatibility questions are our most asked questions. This support article gives you a list of all the devices we know about (and most have tested ourselves) that are compatible with Future ADHD Digital Planners, and all the devices we know don't work too! 

This is an evolving list, so if you have a device-type not listed below please contact us so we can help you troubleshoot and/or help others in future. Thank you to everyone who has contributed to this for our community.

IMPORTANT: GoodNotes 6 has just been released (Aug 9) with a new major limit on file sizes for free accounts, meaning the Future ADHD planner no longer works in GoodNotes for free 😥. It will continue to work with the premium version of GoodNotes. More information & next steps here.
