Task

Mood, money, food, sleep, workouts, health, goals and a calendar are usually scattered across five to seven apps, and each keeps its data somewhere of its own. What is needed is one place for a whole life that works on a Mac and on a phone, does not lose records and shows nothing personal to anyone: even the sync server must not see the content. The client wanted all of it in one app that works on a Mac and a phone, with everything personal kept closed and encrypted. After that, people he lets in himself can use it. The system is closed: it holds personal data, so outsiders have no access.

Solution

An app of 13 sections on one data engine, with its own design system and a sync server.

  • Day summary. Yesterday’s results in the morning, today after lunch: mood, spending, the next meeting, the one task that matters most.
  • Finances. Accounts, transactions, budgets by category, recurring payments with confirmation, savings pots, debts, analysis and bank statement import. Three currencies (roubles, drams, dollars), monthly totals in one of them at the central bank rate, fetched automatically.
  • Mood and diary. Rate the day with one tap, tags, text, photos, a lock on the diary, a year view.
  • Food, workouts, sleep, health. Calories and macros, water, fasting, a directory of 75 foods, recipes and a weekly plan; workouts and habits; sleep, weight, medication; import from Apple Health (about 185 types) and screen time.
  • Goals, media, calendar, observations. Tasks and goals, books and ideas, a calendar with meetings, observation notes.
  • Work meetings from the assistant. Meetings the assistant set up from client correspondence and I confirmed appear in the calendar and in the “Now” card with a “Join” button: the call link is checked against an allowlist (Telegram, Meet, Zoom, Teams, Telemost).
  • Reminders and imports. Daily reminders arrive as a notification on the Mac and in the browser; data is imported from Apple Health and bank statements; screen time from the Mac is counted automatically.
  • Sync and friends. An own server, encryption on the device: the server stores only ciphertext. Friend accounts with approval, read-only sharing of sections, password change.
  • “Tell me about your day”. One free-form story, and an assistant sorts it into sections; nothing is saved until you confirm.
  • Reliability. An event log with a clock on every record, conflicts and the offline queue resolve themselves; a corrupted record does not break a section; a year of data opens in under 0.2 s per screen.
  • Own style. Monochrome, colour only in charts, line icons, light and dark theme following the device, “liquid glass”.

Result

The app is live and used every day: a Mac program and a web app for the phone, with the sync server in production. What remains: testing on real iPhones and Android phones, and a Windows build.

The project at a glance

Data as of 27 October 2026
ClientA person whose personal affairs were scattered across several apps. The name is not given. The goal: one closed app for a whole life on Mac and phone: finances, tasks, health and work meetings
My roleFrom idea to launch: design, the Mac app, the web app for the phone and the server
ResultFinances in three currencies, tasks, health and work meetings in one private app on Mac and phone; the server sees only encrypted data
SizeA Mac program, a web app for the phone and an own sync server with no external dependencies
PlatformsA Mac program and a web app for iPhone, Android and Windows
DataKept on the device; sync through an own server that only ever sees encrypted content
ReliabilityA corrupted record does not break a section; a year of data (8,238 records) opens in under 0.2 s per screen
BackupsNightly server copies, a trial restore once a month
AccessA closed system: the client uses it, followed by people he lets in himself. Outsiders cannot sign in, because personal data is inside
ConnectionsWork meetings from the assistant with a join-the-call button; reminders on Mac and in the browser; Apple Health import; screen time from the Mac; a bank statement as a file; central bank rates
