Getting A Weight Loss Journal Working In GoodNotes
I spent three months building a system that was so complicated I barely used it, then scrapped it and went back to something dead simple. The reason I tell you this upfront is that most people I see trying to log weight loss data in GoodNotes end up spending more time fiddling with the app than actually tracking anything useful. The best approach I've found is straightforward, but it requires a few specific choices to work without becoming a chore. The core mechanic is this: you create one daily page and log four things every single day. Weight. Calorie intake. Steps or workout type. One line of honest commentary. Nothing more. When you use the pen tool instead of typing, there's a small cognitive benefit—writing by hand forces you to actually look at the number before moving on, and that moment of attention matters more than you'd think. Here's how I set it up now. Open GoodNotes and create a new notebook called "Weight Log." Inside that notebook, create a template page once. I draw a simple grid using the ruler tool so the lines stay straight. Three columns for the date, numbers, and a notes section. I stamp a small calendar icon at the top left so the page has a visual anchor when I'm flipping through old pages. The template takes me about four minutes the first time, and then I duplicate it daily. Duplicating from the template is faster than rebuilding the layout each morning.
I do not recommend trying to make these pages look pretty. Colored backgrounds, decorative fonts, highlighter borders—it all sounds like a good idea until you've logged twenty days and your only motivation is aesthetic completion rather than actually reading the data. Ugly pages that get filled out beat beautiful pages that sit empty. There's a specific problem I ran into around week six that almost made me quit entirely. I had been writing my daily weight as a single number like "184.2." The issue is that weight fluctuates naturally by two to four pounds throughout the day based on hydration, sodium, and digestion. When I saw the number jump from 184.2 to 186.8 the next morning after a salty dinner and poor sleep, I panicked and assumed I'd gained fat overnight. I didn't. It was water retention. I stopped panicking when I switched to taking my weight only after I used the bathroom and before I ate or drank anything in the morning, and then I recorded the weekly average instead of fixating on any single day. That change alone made the system actually sustainable for me. GoodNotes doesn't have built-in charts or automatic graphing, which is probably its biggest weakness for weight tracking. You can search your handwritten pages by tapping the magnifying glass icon, and if you write "weight:" before each number, the search function can surface all those entries across your notebook. It's not elegant, but it works. I export my PDF pages to a spreadsheet once a month just to calculate averages manually. It takes about ten minutes per month and it gives you actual data you can look at without guessing.
Another detail people overlook is the importance of consistent lighting when you're writing your daily entries. GoodNotes has a text selection tool that works on handwriting if the letters are clear enough. Messy, rushed cursive turns into garbage when the app tries to recognize it. I write each digit slowly. The extra two seconds per entry adds up to nothing meaningful over a year, and it prevents you from having to re-enter data because you wrote a "4" that looks like an "9" or vice versa. Here's a counter-intuitive point: tracking calories inside GoodNotes is usually a bad idea. The effort of logging every meal by hand is high, and the accuracy is low because you're estimating portion sizes by eye. Most people I know who try to hand-write their calorie count in GoodNotes abandon the system within three weeks. A better hybrid is to log calories in a dedicated app like Cronometer or MyFitnessPal where barcode scanning and database entries make it fast, then just write a single total number in your GoodNotes journal each evening. That way you're maintaining one daily habit of opening the notebook and writing four things, instead of juggling three different systems that all compete for your attention. Step count or exercise can be logged as a short phrase. "Walk 7,200 steps" or "Lift 30 min" is enough. You don't need granular detail about sets and reps unless you're doing a specific program where that data matters to you. For weight loss specifically, the calorie deficit is what drives results. Exercise type is secondary context, not the main lever.

There are template packs you can download from the GoodNotes marketplace that claim to handle weight loss tracking automatically. I tried three of them over a year. They all share the same problem: they include so many fields—meal photos, mood ratings, sleep quality, water intake, hunger scale—that filling them out becomes a fifteen-minute ordeal every night. The friction kills consistency. I recommend building your own one-page template instead, even if it looks basic. The template you actually use is the one with the fewest fields you can sustain for six months straight. If you want a starting point, you can find free daily journal templates on the GoodNotes website or through their community forum. Search for "daily health log" or "daily tracker" and pick a layout with a simple table structure. Import it into your notebook, modify the column headers to match your four tracking items, and duplicate it daily. I've never paid for a template pack, and I don't think you need to. One more thing that's worth mentioning: the backward-looking review. At the end of each week, spend five minutes scrolling through your seven pages. Look for patterns. Did the days with higher step counts correlate with lower weight? Did you notice that certain foods always show up as commentary before a weight spike? This review step is where the system actually starts giving you information instead of just storing data. Without it, you're just collecting numbers you'll never look at again.
The main failure mode of this approach is inconsistency. If you miss three days in a row, you'll likely skip a week, then a month, and then the notebook becomes a graveyard of abandoned pages. The workaround I've seen work is keeping the notebook open on your home screen or in your Quick Access folder so there's zero friction between deciding to log something and actually doing it. Opening the app and hunting for the right notebook is a different kind of friction that breaks the habit loop. GoodNotes also syncs across devices through iCloud or Google Drive depending on your setup, but syncing can sometimes introduce conflicts if you're editing the same notebook from your phone and tablet simultaneously. I use the phone for daily entry and the tablet only for weekly review and PDF export. That separation eliminates sync conflicts and makes the whole workflow cleaner. I've been doing this daily journal format for about fourteen months now. The weight loss happened because I maintained a consistent calorie deficit, not because the journal itself did anything magical. But the journal gave me the feedback loop that made the deficit sustainable. Without seeing the numbers in front of me each morning, I would have gone weeks without realizing how much I was actually eating. That's the real value. Everything else is just setup details.
