Musteri
Trade fair leads, follow-ups
Free · In-App Purchases
Meet at the fair. Save. Follow up. Capture business cards and QR codes in seconds and get a follow-up list after every fair. Works offline, no account needed.
Musteri 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. No ads.
FAIR MODE
Pick the fair from the TOBB calendar and start Fair Mode. Every capture finds or creates the customer and the contact person, links them to the fair, marks the interest and schedules the follow-up. It works even with no signal in the hall.
• Type the name, Save now: the shortest path is two actions
• Business cards and QR codes are read on the phone and the capture opens filled in
• A quick form or a voice note for visitors without a card
• Goal and live progress: Live Activity, Dynamic Island, widgets and the watch
FOLLOW-UP LIST
Every fair gets its own follow-up list: who is still waiting to hear from you, and what you promised. WhatsApp, call, e-mail or SMS with ready templates; every contact is logged on the timeline. Follow-ups remind you when they are due; tick them off or snooze them.
CUSTOMER BOOK
• Companies, branches, billing and shipping addresses; open on the map, get directions
• Contact persons: several phones and e-mails, title, department, notes
• Notes, calls, meetings, visits and fairs on one timeline
• Turkish-aware search: type "sisli" to find "Şişli"
OFFLINE AND ACCOUNT-FREE
Everything is saved on your device first. Sign in with a passkey if you want sync and backup; everything comes back on a new phone.
IPAD, WIDGETS AND APPLE WATCH
On iPad the list and details sit side by side. Home screen, lock screen and StandBy widgets, a Control Center control and Shortcuts. On Apple Watch: Fair Mode, voice notes, follow-ups and complications.
