WINTER ARC · FIELD GUIDE
Paper or digital habit tracker? A 90-day workflow
Content reviewed
The useful question is where you will actually record an ordinary day. Paper removes the need to open a screen; a local tracker makes corrections and summaries easier. Neither makes the commitment happen for you.
Choose by the task
| Task | Paper grid | This local tracker |
|---|---|---|
| Daily access | Visible wherever you leave it; no device required | Available in the browser holding the data; requires this page to load |
| Correct a mark | Erase or annotate legibly | Uncheck or use session undo |
| Weekly review | Count marks yourself | Seven-day per-rule totals are calculated |
| Keep a second copy | Make a copy and store it safely | Export JSON; CSV is a readable report |
| Privacy | Anyone with the sheet can read it | Anyone with this browser profile may read it; exports are not encrypted |
A hybrid workflow without double counting
- Choose one source of truth. For example, record daily on paper and reconcile into the tracker each Sunday.
- Use the same start date and rule wording in both. Print from the active arc to avoid mismatched columns.
- On review day, select each past date and enter only the actions you actually did. A check is a boolean, so clicking Complete day again does not create a second completion.
- Resolve disagreements explicitly. A paper note can explain a corrected mark; a saved daily note can explain a digital correction.
- Export a JSON backup after reconciliation. Put the paper and the backup somewhere appropriate to their contents.
Bad example: one person fills a shared sheet while another edits the same browser arc without agreeing which record wins. This prototype has no collaborative merge. One browser origin holds one active arc; another tab’s update invalidates stale undo and drafts.
Print a useful sheet
- Create an arc with one to five rules, then choose Print in the 90-day view.
- Review all three 30-day tables covering 90 dates. Saved checks are included; daily notes are excluded.
- Choose Print these sheets. In the device dialog, select A4 portrait and inspect margins and page count before printing or saving PDF.
Each 30-day table may span multiple printed pages. Actual page count depends on rule length and print settings. Long rule names wrap without truncation. Native printer settings differ, so a preview is not proof of a successful print job. This prototype’s app preview is tested; physical printer output still needs device verification. There is no handwriting recognition or automatic import of a photograph.
When another tool may fit better
HabitKit presents a visual tile-based habit tracker for iPhone and Android. Loop describes an Android habit tracker with statistics and an ad-free, open-source approach. These official descriptions were checked October 4, 2026; their apps were not installed or benchmarked here.
Choose a native tool if its device integration matters more than a fixed 90-day sheet. This prototype focuses on a bounded local record, explicit backups and a print view. It has no cloud synchronization, push reminders or guaranteed offline installation.
