Three roles, three steps
- Company: applies and gets the account approved; adds its guides from the panel and monitors live broadcasts, emergency help requests and survey results
- Guide: creates a group, shares the QR code or 6-digit code, taps the microphone and starts speaking
- Pilgrim: scans the QR code with the phone camera and taps "Start listening"; optionally adds it to the home screen and turns on notifications
Pilgrims do not need to download anything from the App Store or Google Play; the broadcast opens in the browser. When the broadcast stops, the audio stops, and it resumes automatically when the guide starts again. Audio plays while the page is open even if the phone is on silent.
Group management alongside the broadcast
- One-tap roll call: an "I'm here" button appears on every phone, and those who respond are listed
- Emergency help: a pilgrim requests help with one tap; the guide receives an alarm and the location with directions
- Group map: locations of pilgrims who give permission, sorted by distance to the Kaaba
- Voice announcements: arrive as a notification and are read aloud on the pilgrim's phone
- Schedule and voice messages: the daily schedule is shared and the next event is highlighted; pilgrims leave voice messages and the guide sends voice notes to the group
In-app tools
Alongside the broadcast, the pilgrim's phone has a prayer library of 76 prayers sourced from Diyanet, a tawaf and sa'y counter, a qibla compass, Mecca and Medina prayer times and a guide to 42 visitation sites. With elderly pilgrims in mind, text and buttons are large, and starting to listen takes a single step.

Packages and trial
The Starter package is for small agencies with few guides: live audio, emergency help and voice messages, announcements and schedule, prayer, tawaf and qibla tools. The Pro package adds roll call and satisfaction surveys, the group map and broadcast recording for mid-sized Umrah operators. The Enterprise package offers the company logo and colors, higher guide and listener limits and priority support for large Umrah and Hajj organizations.
Prices and limits are provided after application. Every package includes a 7-day free trial; no credit card is required, and it can be tested with a real group once the application is approved.

Frequently asked questions
What is sesCell?
sesCell is a multi-company system in which Umrah and Hajj guides broadcast live audio from their phones and pilgrims listen in the browser via QR code; it is live at sescell.com and was developed by Hakan Sevimoğlu.
Do pilgrims need to download an app?
No. When they scan the QR code, the broadcast opens in the browser; they can add it to the home screen if they wish.
Does it work without internet?
No. Both the guide and the pilgrim need internet; 4G/5G coverage is strong in Mecca and Medina, and hotels have Wi-Fi.
Can multiple guides broadcast at the same time?
Yes, depending on the package. Each group has its own 6-digit code and QR code.
Is the data compliant with KVKK (Turkish data protection law)?
Pilgrim data is minimized; only an anonymous device ID is stored. Location sharing is optional and can be turned off at any time; servers are located in Turkey. Broadcasts are recorded only in the package that includes recording.
Is there a trial period?
Yes. It is free for 7 days, and no credit card is required.
