povseDnev: everyday tracker for habits, tasks and notes

The idea

I was using a habit tracker, a to-do app, a notes app and a spending log, and none of them talked to each other. povseDnev ("for every day") brings them into one place, with a Today screen that shows the day at a glance: habit progress, the week, countdowns, goals, a quote of the day and a single agenda of tasks and events.

It has no accounts and no server. Everything stays on the phone.

povseDnev banner: Every day, in one calm place. Habits, tasks, notes, journal, money, with two phone screens — Store banner: the Today and Habits screens.

Features

Habits of six kinds: check-offs, counts, timed habits, things to avoid, specific weekdays and "N times a week", with streaks and 15 presets.
Tasks and reminders with natural-language dates in both languages: typing "Dentist fri 17:30" or "завтра в 7 вечера" sets the date and time. Repeating reminders and calendar export as .ics.
Notes with a markdown subset, #tags, [[wiki links]], version history, a trash, checklists, sketches and voice notes.
Journal, money, subscriptions, birthdays and goals, plus an Eisenhower matrix, inbox and search.
Focus timer (Pomodoro) with a live countdown in the notification.
Reviews: monthly and yearly summaries, insights, a "year in pixels" and 22 achievements.

Three povseDnev phone screens: Today with habit ring and agenda, Habits with streaks, and Money with monthly spending by category — Today, Habits and Money with demo data. Each habit row shows its recent history, completion rate and current streak.

Native Android

The same React and TypeScript build runs as a PWA and inside a Capacitor 8 Android shell. On Android, my own Java plugins add what a web app can't do:

exact alarms with action buttons, scheduled 60 days ahead
11 home-screen widgets drawn from a data snapshot the app sends them, with taps queued and applied when the app opens
an app lock using the fingerprint or screen lock, with screenshots blocked
dictation, document scanning with Google ML Kit, and a daily backup to a folder the user picks

How data flows

From a tap to a widget

01
Input
Tap a habit or add an item; dates are parsed from plain English or Russian
02
State
One typed data object for the whole app
03
Persist
Saved to local storage, photos to IndexedDB, all on the device
04
Derive
Pure functions compute streaks, stats, reviews, awards and recurrence
05
Schedule
Reminders for the next 60 days go to Android's alarm manager
06
Widgets and backup
A snapshot updates the widgets; a daily JSON backup goes to a chosen folder

Privacy and quality

There are no accounts, analytics or network calls in the app. Data is a single JSON document in local storage, with photos in IndexedDB, and can be exported as JSON, CSV or .ics. Locked notes are hidden behind the device lock rather than encrypted, and the app says so. The core logic (habits, streaks, date parsing, recurrence, reviews) is pure TypeScript covered by unit tests, and one GitHub Actions workflow tests, builds and ships the web app, the landing page and a signed Android build.
