Get a believable incoming call screen without asking anyone to ring you. Skip awkward exits, prank a friend, or rehearse a moment with a fake call that looks and sounds the way you choose. Pick a caller name, subtitle, and photo for your incoming call. Choose quick presets like Mom, Office, and Unknown number, or browse the caller library with picks like Pizza Delivery, School Nurse, Vet Clinic, Boss, and Group Chat. Tap the dice button for a surprise fake call setup with a random caller, ringtone, and theme. Choose an audio call or, with Pro, a video call look. Set the ring style, preview the ringtone before you start, and add vibration while it rings. Switch between call themes including cinematic dark, light frost, and ocean blue. Start now, set a short delay, show a full-screen countdown in the app, or schedule a notification for later. Answer to open an in-call screen with mute, speaker, and End Call controls. Play spoken answer audio from your typed script, choose a voice, and adjust the speaking pace. Use script presets like urgent, running late, or wrong room for quicker setup. Record your own answer clip and play that after you answer. Turn on auto-decline so the ringing stops if nobody answers in time. Shake your phone to start the call now, use Home Screen quick actions, or launch a saved setup from Spotlight or Shortcuts. • Get out of an awkward conversation by starting an Unknown number fake call with a short countdown. • Make a harmless prank call screen for a friend with Pizza Delivery, a caller photo, and a custom ringtone. • Rehearse answering a tough call by using the Office preset, a typed script, and the mute button. • Set a School Nurse or Doctor caller for a role-play moment with vibration and a themed incoming screen. • Keep a saved scenario ready for later and start it from Spotlight, a quick action, or Shortcuts. Incoming Prank Call Sim helps you create a simulated incoming call for jokes, practice, and graceful exits. Everything happens in the app, so you can set up the fake call, preview the ring, run a countdown, answer, and end the call in one place with no real phone call involved. Pro adds more ways to sell the moment: video call mode, custom ringtone import, six extra themes, recurring schedules, more saved scenarios, Personal Voice for spoken scripts, and an ad-free experience. Camera access is only needed for video call simulation, microphone access is only needed if you record your own answer clip, and voice access is only needed if you choose that option. Make your next fake call feel right for the moment. Set the caller, pick the ringtone, choose the timing, and start your incoming call in seconds.
