HumFutNever uses your microphone
HumFut never records a call and never listens to one. It only adds the sounds you choose.
Now you can say it on a call.
Tap a sound on your iPhone and whoever you’re talking to hears it. Works on Phone, FaceTime, WhatsApp, Zoom and any other call.

Mom heard that.
Your chats have reactions. Your calls just have voices.
In the group chat you’d answer good news with a GIF or a tapback. On a call, all you have is your voice. HumFut gives calls their own reactions: sounds the other person actually hears.
How it works.
HumFut mixes the sound into your call, right alongside your voice. The person on the other end hears it on any phone, with nothing to install.

Step 1
Call like you always do
Start a call the way you always do: Phone, FaceTime, WhatsApp, Zoom or any other app. HumFut never places a call itself.
Step 2
Turn on Call Sounds
One switch in HumFut. It uses the iOS permission Apple built for adding audio to calls, and never your microphone.
Step 3
Tap a Pad
The sound goes into the call with your voice, and they hear it straight away. Try any Pad on your own speaker first.
A soundboard for your calls.
Every Pad below is something HumFut does. Press one to send it into the call and see what it does.
Reactions, one tap away
Your sounds live on big, colourful Pads. Tap one and the other person hears it instantly, mixed right into the call.
- Starts with Laugh, Mm-hm, Applause, Sigh, One moment and Bye
- Add the internet’s favourites: FAAAH, Bruh, Vine boom
Share from any soundboard
Found the perfect sound on a soundboard site? Tap Share, choose HumFut, and it lands in your Library with its own name.
- Works from Chrome and Safari
- Apps that share audio files work too
Capture from your apps
Hear it in a video, a game or a podcast? Start a capture, play it, and HumFut keeps the sound with the silence trimmed off.
- Stops by itself after 60 seconds
- Keeps only the app’s audio, never video or your microphone
Import from Files
Already have an MP3 or M4A? Add it from Files. Up to 30 seconds becomes a Clip for a Pad; anything longer becomes a Track.
- Downloads, iCloud Drive and AirDrop
- Long files play as background music
Music under the call
Play a Track under the whole call and loop it. Your Reactions play on top.
- Two levels: They hear and You hear
- Start with the built-in Ambience
Collections
One set of Pads for game night, another for work calls. Collapse the ones you’re not using.
- Search when you have lots of Pads
- Swipe between them on Apple Watch
Make it yours
Hold a Pad to rename it, give it one of six colours and any emoji, or move it to another Collection.
- Trim exactly where it starts and ends
- Set how loud each sound plays
Try it before they hear it
Hear any Pad on your own speaker first, so you know it’s the one. Trying sounds is always free.

- Nothing goes into a call until Call Sounds is on

How to add sounds
Three ways to get any sound in.
Pick where your sound is. Then tap along on the iPhone, one real step at a time.
Set the vibe under the whole call.

- Loop it, pause it, stop itTransport controls sit right on the Track strip.
- Two levels: They hear and You hearKeep the music soft for them and even softer in your own ear.
- Bring your own TracksImport music you own, or start with the built-in Ambience.
Fire from your wrist.
Leave your iPhone on the table and play Pads from Apple Watch. Swipe between Collections, adjust levels, or tap the square to stop everything. Your Pads and Collections show up on the Watch; the sound always plays from your iPhone.
Private by design.
HumFut adds sounds to your call and does nothing else with it. It doesn’t listen, record or send anything anywhere.
Nothing leaves your devices
No servers and no analytics. Your sounds stay on your iPhone. Privacy Policy
No account, no tracking
No sign-in, no ads and no tracking of any kind.
Your first 3 calls are free.
After that, one purchase lets the other person hear HumFut on every call, forever. No subscription. Building your library and trying sounds on your own speaker are always free.
Quick answers.
Which calls does it work with?
Any call on an iPhone running iOS 26 or later: Phone, FaceTime, WhatsApp, Zoom and other calling apps. HumFut adds audio only while a call is connected, and it pauses while you’re screen sharing.
I don’t see HumFut when I tap Share.
HumFut shows up when what you’re sharing is an audio file. On a soundboard site, open the sound’s own page and share from there. Also open HumFut once after installing it, so it can finish setting up.
How long can a sound be?
Clips for your Pads can be up to 30 seconds. A capture stops by itself after 60 seconds and keeps the first 30 seconds of sound. Anything longer can be imported as a Track for background music.
Why did HumFut refuse a sound?
HumFut is for sounds that are obviously not real: airhorns, laugh tracks, funny clips, music. It won’t add sounds that could be mistaken for something real on a call, like sirens, phone-menu tones or ringtones.
The other person can’t hear my sounds.
Check that Call Sounds is on and the call is connected. Muting the call mutes HumFut too, because it uses the same audio path as your voice. More troubleshooting
