Your next deal is already in your database. Now it can reach you anywhere. Real estate doesn't happen at a desk, so Fello doesn't either. The iOS app puts your leads, your conversations, and your next best move in your pocket. Built for agents who are always moving between showings, listing appointments, and everything in between. Fello finds the opportunity. Felix, your AI teammate, works it around the clock, calling, texting, and emailing your database so no contact goes cold. When someone's ready to talk, Felix hands the conversation straight to your phone, live, with the full history and context, so you're stepping into a warm conversation instead of a cold one. What you can do: Get notified the instant it matters. Real-time push alerts when a contact raises their hand, a new lead comes in, or your database needs your attention, no more checking back three hours later. Take the call, wherever you are. Incoming calls and texts, including live handoffs from Felix, ring right on your phone. Act on the moment instead of finding it later. Sign in in seconds. One-tap Google Sign-In means no new password to create or forget. Land exactly where you need to be. Tap a shared link from email or text and go straight to the right contact or screen, not a generic home page. This app is built for existing Fello customers. Sign in with your Fello account and your entire database comes with you, no separate setup required. Fello finds it. Felix works it. Now you can close it from anywhere.
