Customer tracking for people who sell face to face

Meet at the fair. Save. Follow up.

Müşterim keeps your customers, their addresses, contact persons and the trade fairs where you met them in one place. Save a business card in seconds, see who is still waiting after the fair, and call or WhatsApp them in one tap. No internet or account needed.

See Fair ModeQuestions

Coming soon to Android and Wear OS, then iPhone and Apple Watch. No ads.

Fair Mode

Capture at the stand in seconds

Pick the fair — it comes from the TOBB trade fair calendar, or you add it yourself — and start Fair Mode. Every capture finds or creates the customer and the contact person, links them to the fair, marks their interest and schedules the follow-up. It works even when the hall has no signal.

  • Scan a business card

    Text is recognised on the device; name, title, company, phone, e-mail and address land in the right fields.

  • Scan a QR code

    vCard and MECARD codes become a contact in one go.

  • Quick form or voice note

    Save a visitor without a card in two fields, or record the conversation as a voice note.

  • Hot, warm, cold

    Set the interest level in one tap; the follow-up list is sorted by it.

Follow-up list

Nobody is forgotten after the fair

Every fair gets its own follow-up list: who is still waiting to hear from you, and what you promised. Reminders on your phone, widget and watch.

  • One-tap contact

    WhatsApp, call, e-mail or SMS with ready templates. Every contact is logged on the timeline.

  • Progress per fair

    How many people you met at a fair, how many you got back to, how many are waiting.

  • Reminders and snooze

    Follow-ups arrive as notifications when they are due; tick them off or snooze them.

Customer book

Your customer book, in your pocket

Companies, their addresses, contact persons and everything you did with them on one timeline. You can save a person before you know their company.

  • Addresses

    Head office, branch, billing, shipping and warehouse; open on the map, get directions.

  • Contact persons

    Several phones and e-mails, title, department and notes.

  • Timeline

    Notes, calls, meetings, visits and fairs in order.

  • Turkish-aware search

    Type “sisli” to find “Şişli”, “igdir” to find “Iğdır”.

Offline and account-free

No signal in the hall? No problem.

Müşterim works on your phone first. Everything is saved on the device and the screen never waits for the network. You do not have to create an account.

    Install it and start. Your records stay on your device only.

    Sign in with a passkey, Google or Apple to turn on sync, backup, the watch and multiple devices.

  • Everything comes back on a new phone

    Sign in and your customers, contacts, fairs and follow-ups are restored in full.

Frequently asked questions

Does it work without internet?

Yes. Capture, search, follow-ups and export all run on your device. If you are signed in, changes sync by themselves when a connection is back.

Do I need an account?

No. Müşterim works in full without one. Signing in turns on sync, backup, the watch app and multiple devices.

Where is my data stored?

On your phone first. If you sign in, a copy is kept on our server in the European Union (Finland) for sync and backup. The privacy policy has the details.

Will what I saved ever be behind a paid plan?

No. You can export all your customers and contacts as CSV and vCard, free and without limits. There are no ads in the app.

Which fairs are already listed?

Fairs from the TOBB trade fair calendar are listed ready to pick. You can add any other fair, conference, congress or meeting yourself.

Is the business card photo sent anywhere?

No. The photo is processed on your phone and only the fields you confirm are saved.

Which devices will it run on?

First on Android 16 and later phones and tablets and on Wear OS watches, then on iPhone and Apple Watch.

Can I use it with my team?

For now Müşterim is for personal use. Teams and shared workspaces are one of the next steps.

How do I delete my account?

In the app under Settings → Account → Delete account, or by e-mail to musterim@sayfa.app. The account deletion page walks you through it.
