I wanted the day to fit on one sheet. Protein toward a number, water, a yes or no on whether I followed the plan, and an optional fasting window. Not a social feed, and not a diagnosis.
What the sheet holds
The iPhone app is the daily sheet. Apple Watch is the companion. Mac is a menu bar and a today view. The repo also documents Health integration, widgets, reports, and export to CSV, PDF, and Excel. Saved meals and a local food catalog stay on the device. A barcode can ask Open Food Facts. A USDA key, if you add one, goes in the Keychain.
No backend is not the same as no cloud
There is no account and no server of mine in the middle. The journal can sync through iCloud between iPhone and Mac. That is optional, and it is still a cloud feature. I would rather say that plainly than hide it behind “no backend.”
The boundary
The README is explicit, and the screen says it too. This is not a medical device. It does not diagnose ketosis, BMI, or anything else. A ketosis toggle is a self-report. Weight and BMI are there if you want them, collapsed, not as a verdict.
App Store submission is separate from this source repository. Updates, once the app is on the store, would come from the App Store rather than GitHub Releases. I am not describing Daily On Plan as publicly available on the App Store. The source is public. That is the status I can actually stand behind.
