Getting a digital planner actually working for you is mostly about file management and habit, not features
I've been building digital planners in GoodNotes and Notability for about seven years now. What I've learned is that the vast majority of people set themselves up for failure by obsessing over pretty templates before they understand what the tool can actually do for their specific workflow. The difference between a planner you use daily and one you abandon in three weeks usually comes down to hyperlinks and navigation, not aesthetics. The simplest approach is starting with a clean PDF template in 1080x1440 or that A5 ratio and building from there. You need a monthly overview, weekly spreads, and daily pages with space for notes. Stack them in that order and link them with bookmarks. Bookmarks in GoodNotes and similar apps work differently than hyperlinks in a browser. When you tap a bookmark, it jumps to that exact page number. Hyperlinks are better for linking between pages within the same document. For a functional planner, bookmarks handle your main navigation while hyperlinks manage things like clicking a date to jump to its daily page. Here is something most tutorials skip: tab dividers. Creating section dividers with labeled tabs on the side makes flipping through a 200-page planner bearable. Without them you're scrolling and hunting. I usually create a single divider page per month and set it as a bookmark target. That way the January monthly overview is always one tap away from anywhere.
The real friction point most people hit is date management. You build a beautiful planner for January and then you're stuck with static text that says January 1st through January 31st. The workaround is simple but tedious. Use a fillable PDF created in Adobe Acrobat or a tool like GoodNotes' built-in text field support. Put every date as a text field rather than flat text. Then when a new month rolls around you just overwrite the dates. It takes about twenty minutes per month if you have a consistent layout. Alternatively, some people just use the free GoodNotes date replacement feature which swaps out an entire date block in one action, but it's finicky and breaks sometimes. I hit a wall last year with a client who wanted a quarterly planner with habit tracking integrated into the daily pages. The problem was that GoodNotes doesn't do conditional formatting or auto-tracking. Every checkbox you tap is just a visual mark. There's no logic engine. I ended up building a separate tracker sheet with a simple tally system where users manually log completions at week's end. It was clunky but it worked. If you need actual data aggregation or smart reminders, you're better off with something like Notion or Apple Reminders rather than a flat PDF planner. No amount of hyperlinking will fix that limitation. Another counter-intuitive thing about building these is file size. People tend to use high-resolution images for every background element and sticker pack. A single planner with 180 pages loaded with 300dpi PNG backgrounds can balloon to over 400 megabytes. That makes the app slow, crashes it on older iPads, and basically makes the planner unusable in practice. Compress everything. Use JPEG backgrounds instead of PNGs. Keep image dimensions reasonable. I found that scaling backgrounds to 150dpi max and converting to JPEG dropped my typical planner file from 380MB down to about 45MB with visually indistinguishable quality.
Also consider that hyperlinks don't work reliably across different apps. A planner built with all its navigation in GoodNotes might not import cleanly into Notability or LiquidText because each app handles PDF annotation differently. If you plan to sell or share your planner, test it in at least two different apps before finalizing. I learned this the hard way after spending a week debugging broken links only to discover the issue was app-specific rendering. For actual implementation, here is the path I recommend. Start in Canva or Figma to design your spreads. Export as PDF. Open in Adobe Acrobat Pro and add your hyperlinks and bookmarks. Test in GoodNotes and Notability separately. Fix any broken links. Then compress the file. The whole process for a basic 150-page monthly planner takes me about four to six hours on a first build, and maybe forty-five minutes to update the dates each month after that. If you want something to work with immediately, the simplest download path is building your own from a blank PDF template. Sites like Creative Market and Etsy sell premade template shells, but they often come bloated with features you don't need and styled for aesthetics over function. The free options in Figma community files are usually cleaner starting points. Look for ones that already have proper layer naming and vector shapes rather than rasterized backgrounds. That makes editing and hyperlinking significantly easier.

Final notes on what to actually expect
Digital planners work well for people who already have a strong analog planning habit and want to remove paper from the equation. They do not work well if you are trying to build a planning habit from scratch, because the friction of managing hyperlinks and app navigation becomes a barrier. In those cases a physical notebook or a simple app-based system like Apple Notes with templated sections will produce better consistency. Also, if you frequently switch between multiple devices, the cloud sync situation is messy. GoodNotes syncs through iCloud, Notability through Google Drive or iCloud, and files can easily become out of sync. You end up maintaining two versions or losing work when the sync conflicts. The core value of a digital planner is portability and editability. You carry months of planning in your pocket and can modify any page instantly. But that only matters if you actually open the app and use it, which comes down to whether the navigation is fast enough that it feels frictionless. If every task requires three taps and two seconds of searching, people won't do it. Every design decision should be measured against that single question.
