My Counter turns your phone into a collection of customizable counters for tracking habits, consumption, recurring activities and goals. Built to be fast for daily life — one TAP per event — with a Glance home-screen widget, detailed statistics (KPIs, bar chart, cumulative line chart), shareable PDF reports, and a differentiated goal system that works both for limits to stay under (coffee, cigarettes) and targets to reach (glasses of water, steps, workouts).
Each counter has a **periodicity** (daily/weekly/monthly/yearly) and the app **silently auto-consolidates** the previous period: snapshot of final values, Achievement generation (SUCCESS/FAILURE/NEUTRAL), and a growing **streak** of consecutive successes. Local notifications for hot-zone (80% of target/limit), period outcome, and a daily 22:00 reminder.
**Time Counter mode** turns the counter into a stopwatch: first TAP starts, second TAP stops — perfect for "phone time", "deep study time", "driving time". Sessions are saved with start/end/duration.
**Email accountability**: each counter can have one or more addresses (coach, friend, mom) separated by comma/semicolon/space. At period end the app automatically generates a summary PDF and opens the system mail client with all addresses pre-populated and PDF already attached — no backend, no login, you confirm and send. Global master switch to disable everything while on vacation.
**Global webhook** (opt-in): on every consolidation the app POSTs JSON to a configurable endpoint, with a complete payload (counter, goalType, final value, target, outcome, streak) and `X-myCounter-Signature` HMAC-SHA256 header if a secret is set. Two-level architecture: one global endpoint + an optional **per-counter tag** (`vices`, `health`, `work`) for server-side routing. Compatible with Zapier, n8n, IFTTT, Make.com.
