Our Purpose
Why Now Humming exists
Sharing a song you love shouldn't feel like broadcasting on a noisy public billboard or losing a link inside a busy group chat. Now Humming brings back intimate, mood-first musical expression.
The Modern Mixtape
Cold link-drops miss the emotion behind why you sent a track. Wrap songs in Love, Friends, Family, or Special artwork with a personal message and a voice-over intro.
Co-Listening Without Chaos
Listen to long-form podcasts together in real-time sync. Rooms keep audio uninterrupted with strictly chat-only discussions, timestamp tags, and 1-tap insight bookmarks.
Privacy-First Circle
Discover friends you actually know via on-device SHA-256 contact hashing. Raw phone numbers and address books are never stored on our servers, and private dedications stay strictly between two people.
Inside the App
Built for every way you listen and share
Powered by Flutter, Firebase, and official YouTube embedded playback, Now Humming packs a complete social audio studio behind one effortless interface.
Live & Scheduled Podcast Rooms
Host spontaneous listening rooms or schedule upcoming Listen Parties with RSVP countdowns. Authoritative clock synchronization ensures late joiners snap straight to the host's live timestamp instead of starting at 0:00, with automatic host handover if the host steps away.

FAQ
Common questions
Is Now Humming free, and are there ads?
Yes—Hums, Voice Dedications, Podcast Rooms, and Collaborative Playlists are 100% free to use with no paywalls and no feed ads.
How does Now Humming protect my phone contacts and privacy?
If you opt in to find friends from your contacts, phone numbers and emails are normalized and hashed on your device using SHA-256 before matching. Raw contact lists are never uploaded or stored on our servers, and Private Dedications are restricted strictly to sender and recipient via security rules.
How do Podcast Rooms stay in sync without audio interruptions?
Podcast Rooms calibrate client clocks against server time so late joiners jump straight to the live host timestamp, and continuous drift checks keep everyone aligned—even at 1.25x, 1.5x, or 2.0x playback speeds. Rooms are strictly chat-only so open mics never talk over the episode.
How does YouTube playback work, and can I delete my account?
Now Humming streams public music videos and podcasts using official embedded YouTube players in compliance with YouTube API Services (no audio downloading or ripping). You can permanently delete your account and all stored data anytime in-app via Profile → More Options → Delete Account, or on our Account Deletion page.
