Customer reviews
Sorry! I wrote a review and forgot to put stars!! I loved the previous planners I've used but this version doesn't seem to have functionality with Supernote digest, "to do," and calendar functions or the ability to "insert page". If this were fixed, I would give 5 stars!

I have absolutely loved your previous planners for my Supernote A5X! However, the 2026 version doesn't have the functionality of the previous years. There's no way to add pages (like for longer journal entries), the "digest" feature is completely unusable, as is the ability to circle text and send it to my "To Do" list or the Calendar in the Supernote.
I spent a lot of time setting up my perfect planner before I realized the problems it had. Without these essential features, I won't be able to use the planner anymore and will now have to search elsewhere. Is there any plan to fix this?? I hope!
