Local ledger · Android

The paper ledger for your daily stack.

Daymark is a bound page for the bottles on the shelf. Scan a barcode, log what you took, watch remaining servings, and stamp the day when the list is clear.

Android 7 and later · No account · Data stays on the phone

Daymark Today screen with a dated ledger of remaining supplements

The page

Four tabs. One folio. Nothing that wants a feed.

01 · Today

What is still due

A dated list of remaining items, not a calendar wall. When every line is logged, the page stamps DONE.

02 · Log

The intake record

PAST and FUTURE tabs. Edit or delete a line. Notes stay on the row, like a pencil in the margin.

03 · Stack

The inventory

Every bottle with remaining servings. LOW when stock is thin. Empty when the last serving is gone.

04 · Settings

Housekeeping

Reminders, export, legal pages, and a rate prompt. No account. No cloud sync.

How it works

  1. Step 01

    Add a bottle by name, or scan the barcode. Open Food Facts can fill the label when the code is known.

  2. Step 02

    Set servings, dose, schedule, and an optional reminder. Attach a photo of the bottle if you want the shelf to match the page.

  3. Step 03

    Open Today. Log each intake. Remaining servings drop. When the list is clear, the folio stamps the day.

What stays local

The stack lives in the phone, not a dashboard.

Names, doses, notes, photos, and the intake history sit in a local SQLite ledger. There is no Daymark account and no cloud backup from us. Export a CSV when you want a copy off the device.

A barcode lookup talks to Open Food Facts. Legal pages can load in a WebView. Everything else stays on paper.
