Hey human! I'm ShutUp! — I let you control phone calls without touching the screen.

WAVE
• Single wave over the top of the phone while it rings: silence it. It can only ever silence, so a hand reaching to decline on the screen never answers or hangs up by accident.
• Double wave (two waves in a row): answer or end the call, your choice. Your "bye-bye" over the phone.
• If the phone is moving (you picked it up) or a call only just started ringing, waves don't count.
• Some phones (recent Samsung Galaxy models, for example) have a proximity sensor that can't see a hand above the screen. I tell you when yours is one of them, and "Light assist" adds the light sensor so a slow hover over the top edge in a lit room still counts.

PICK UP
• Phone ringing on the table? Pick it up and I silence it.

FLIP AND FOLD
• In a call, place the phone face down to end the call or mute the microphone. Lift it to unmute.
• On a foldable, closing the phone can hang up.

SCHEDULE
• Tell me who to call and when. At that minute I vibrate, say the name out loud, and dial, from the SIM you picked. Repeat every N hours if you like. Cancel from the notification.

TRY IT FIRST
• The gesture playground shows live what I see, so you can rehearse every gesture without a call and tune the double-wave timing to your pace.
• A Quick Settings tile and a home-screen widget switch me on and off.

HONEST ABOUT WHAT I NEED
• Phone permission to see when a call rings and to answer, end or place calls. Nothing is read from your contacts — the system picker hands me one number.
• An ongoing, silent notification while the master switch is on. Android needs it so I can react the instant a call arrives. Sensors run only while a call rings or is active.
• Optional "Do Not Disturb" access for true silence (without it I switch to vibrate), and "Alarms & reminders" for calls on the exact minute.
• No ads. No analytics. Nothing leaves your phone. Open source (GPLv3): gitlab.com/ritwick7/shutup

WHAT CHANGED IN 2.0
I was rebuilt from scratch for modern Android: new fluid design with dynamic colour and dark theme, reliable always-on call watching, exact and cancellable scheduled calls, and a double wave that no longer triggers the single-wave action too. The automatic speaker toggle is gone — since Android 12 only your phone app may change in-call audio routing, so it could not work any more.

TIP
Wave slowly over the sensor near the front camera, not over the middle of the screen. If waves don't register, open the gesture playground to see what your phone reports, and try Light assist.
