Stop texting "when works for everyone?" back and forth. Pingo makes group scheduling instant. Create a room, share a 4-digit PIN, and everyone marks their availability on a simple grid — no sign-up, no account, no app-switching required from the people you're inviting. HOW IT WORKS - Create a room and get a PIN - Share the PIN with your group — anyone with it can join in seconds - Everyone marks the times that work for them - Pingo overlays everyone's availability into a heatmap, so the best time is obvious at a glance - Confirm a time, and it's locked in for the whole group BUILT FOR HOW GROUPS ACTUALLY SCHEDULE - No accounts — join with just a PIN, get started immediately - Time zone aware — everyone sees times in their own local time, automatically - Live overlap heatmap — see exactly when the most people are free - Home screen widget — your next confirmed event and countdown, right on your home screen - Reopen for discussion — plans change, and Pingo makes it easy to renegotiate without starting over WHO IT'S FOR Pingo is built for the group chat that's tired of counting "who's free Thursday?" Roommates picking a house meeting time. Friend groups planning a trip. Small teams finding a slot without a scheduling tool.
