THE FLUENCY LEDGER - INTERACTIVE DASHBOARD APP by SheetArchitect

A word you saw once is not a word you know.

Every vocabulary tracker on Etsy counts the same way: words seen only go up. It feels good and it lies - a learner who saw 400 words three months ago and never reviewed half of them still "knows" 400 words on that sheet. This one does the subtraction the others skip.

THE CLOCK YOU NEVER SET

Nowhere in this app do you type "last time I reviewed this word." That date comes from your own review log - a lookup straight off every session you actually logged. No review logged, no false credit: the clock starts on the day you first saw the word instead.

And the clock does not run at the same speed for everything. Core words like "ser" and "tener" hold for 24 days without a review. Idioms and one-off topic words - the ones you barely use - fall stale in 6 to 9. Four categories, four intervals, yours to edit in Setup.

THE WEEK THE LEDGER TURNS RED

Ten weeks of history, tracked like a bank ledger: words learned in, words gone stale out, balance carried forward. In the sample set, one week the learner reviewed nothing - and that is exactly the week several idioms and topic words cross their short interval and go stale. Net Change turns negative for the only time in ten weeks. Then the pace recovers. You do not have to trust that the model subtracts - you can watch it happen.

THE NUMBER MOST TRACKERS HIDE

Out of 54 starting words - 10 core, 16 everyday, 18 topic-specific, 10 idioms - and 71 logged review sessions, the Dashboard still shows Words Forgotten Right Now above zero, even with a healthy net pace. That is the finding this tracker exists to surface: some words always slip through, and now you know which category is doing the leaking.

AND HOW FAR THE GOAL ACTUALLY IS

Set your word-count goal in Plan (300, a first milestone toward the 3,000 words that usually mark conversational fluency) and the Dashboard turns your last four weeks of net pace into a plain sentence: at N words a week, you reach your goal in D days. No peace, no false promise - it just says so.

WHAT ELSE IS IN IT

7 tabs plus an FAQ: START HERE, Setup (categories and forgetting intervals), Plan (your goal and recent pace), Words (the vocabulary master list with its own forgetting clock), Reviews (your review log), Weeks (the running ledger), and Dashboard (known vs. forgotten, leak ranking, projection).

WHAT IS INSIDE - 8 PANELS IN ONE APP
- START HERE: Words seen minus words forgotten - the number that's true today.
- Setup: How long a word survives without practice.
- Plan: Your next milestone. Everything else is measured against it.
- Words: One row per word. The forgetting clock reads Reviews - you never set it.
- Reviews: Your practice log. The only source of 'last reviewed'.
- Weeks: Your running ledger: words gained, words lost, the balance carried forward.
- Dashboard: What you actually know today, and how far the goal really is.
- FAQ: The things people ask us most, answered before you have to ask.

WHAT YOU GET
- The Fluency Ledger: one .html app with 508 live formulas, 1 charts and 4 KPI cards.
- A Quick Start Guide (PDF): opening it on any device, saving your copy, themes and styles.
- 8 themes x 3 styles, Save my copy, Export / Import.

HOW IT WORKS
1. Download the ZIP from Etsy (on a computer, or in your phone's browser - the Etsy app cannot download digital files) and open the .html inside.
2. Change a number in Setup. Every panel, KPI and chart follows on the spot.
3. Press "Save my copy": you get the same file with your data inside. Keep it - it is your master copy. Export/Import move your numbers between devices.
4. Pick a theme and a style under Look. Four of the eight themes are dark.
