Planner
The heart of the system: today, inbox, tasks, calendar, projects, goals, habits, a focus timer, statistics and an archive — ten tabs, one place.
- Jalali calendar
- Recurring series
- Eisenhower matrix
- Pomodoro
What is MBS
One workspace instead of six apps
Most tools solve one slice of a day. MBS is built the other way round: the modules share one account, one search box and one calendar, so a task, a reading session and a payment due date all live on the same day.
Connected, not bundled
A goal rolls up from its projects, its tasks and its habits. A focus session lands in your statistics and against the goal it belonged to.
Built for Persian
Jalali calendar with official holidays, right-to-left layout, Persian digits and Rial/Toman — not an afterthought translation.
Your data stays yours
No third-party analytics, no CDN calls, no ads. Two-factor authentication and passkeys are built in, not an upsell.
Features
The modules
Financial
Transactions, debts, cheques, cards, budgets, subscriptions and a full instalment-loan engine that models Iranian lending — including fee-only instalments.
- Rial or Toman
- Loan schedules
- Due reminders
Investments
Shares, funds, gold, currency and crypto in one portfolio, priced live from the Tehran exchange and the open market. A position is derived from its transactions, so average cost, realised profit, a dividend and a capital increase are all things it can actually express.
- Live prices
- XIRR and CAGR
- Capital allocation
Notes
Quick notes with checklists, images, colours and public share links.
Books
Reading sessions, notes, multi-volume series and yearly stats.

Why MBS
Small things that matter every day
Real Jalali calendarWritten from scratch, with Iranian official holidays — not a converted Gregorian date.
Works offlineEvery module is installable and keeps working on a bad connection.
No CDN, no blocked assetsFonts and libraries are self-hosted, so nothing breaks behind a filter.
2FA and passkeysEvery account gets a second factor, and you can manage your active sessions.
Bilingual, both directionsSwitch FA/EN anywhere; the whole layout flips with it, dark or light.
One search for everythingCtrl+K finds a note, a task, a file or a book from any page.
Sign in with GoogleOne tap to create the account — and it still enrols a second factor, because Google proves who you are, not that it is you right now.

FAQ
Questions
Can anyone register?
Yes. Sign up with Google in one tap, or with a username and a password. The account is free and there is nothing to approve by hand any more.
What does the free account actually give me?
The Android app, with everything kept on your own phone — planner, notes, books and money, up to the limits in the table above. It does not sync to the server and it does not open this website; that is what Pro adds.
Do I have to set up two-factor authentication?
Yes, once. Every account enrols an authenticator app or a passkey before its first session — including accounts created with Google, because Google proves who you are and is not a second factor by itself.
Where is my data stored?
On the MBS server, in your own account. Nothing is sent to third-party analytics or advertising services, and no external CDN is used.
Can I export my data?
Yes — every module has a backup menu that exports to JSON, and the exports import back.
Does it work on a phone?
Yes. Every module has a layout designed for phones, and each one installs as an app from the browser.
Is there an Android app?
Not yet. In the meantime you can install any module from your browser's menu — it behaves like a native app, offline included.
Android app
The free plan lives here: the whole workspace on your phone, with your data kept on the device. Until it is listed, every module installs from your browser menu and works offline the same way.

A free account takes one tap with Google, and nothing about it expires. Move up to Pro whenever the free ceilings start getting in your way — not before.
