Push-to-talk walkie-talkie, video meetings & live map. Encrypted private rooms.
Spotrum turns your phone into a push-to-talk walkie-talkie (PTT two-way radio) for teams, families, events and communities — plus video meetings, a live location map and AI meeting notes. One room, three ways to talk: switch anytime without leaving it. Free to start, with end-to-end encrypted private rooms.
🎙️ WALKIE — PUSH-TO-TALK RADIO
Tap, speak, release. A group walkie-talkie for up to 2000 people in one room, over Wi-Fi or mobile data, with no range limit. Talk turns, a warm mic and classic radio sounds make it feel like a real two-way radio — on the road, at festivals, on job sites, on the slopes and on group trips.
📣 PODIUM — LIVE BROADCASTS
A stage for talks, briefings and live events. Hosts and presenters speak, everyone else listens, and hands go up for questions. Put a document on stage, turn the pages and point at it live.
🎥 CONFERENCE — VIDEO MEETINGS
Video calls with background blur and virtual backgrounds, noise suppression, screen sharing, reactions and Q&A.
🗺️ LIVE LOCATION MAP
See where your people are in real time and how far away everyone is. Drop a meeting point so the group knows where to gather. Share your precise or approximate location — or keep it off. You decide, room by room.
✨ AI MEETING NOTES (PRO & PREMIUM)
Record a talk and get a transcript with speaker names, a summary and chapters. Every recording report is digitally signed and can be verified with a QR code, so your meeting minutes stay tamper-proof.

Map: follow someone on the way, see the walking time, long-press to set the meeting point.
Theme: light, dark or auto. Give rooms a colour, one of 50 icons and a pattern right when you create them.
A notification opens what it is about. The app tells you when a newer version is out.
