Keep score together. Ding everyone.
Humdinger is a highly customizable social score tracker. Create an event, share it through any messenger, and tap to bump the score — firing a custom notification and sound to everyone following along. Serious enough for workouts and fantasy football, silly enough for the bar tab.
Free to download. iPhone, iOS 26 or later.

Create
Pick a template, or build your own
Start one-tap from Tally, Shared Goal, Leaderboard, Teams, or Streak — or compose your own from simple primitives. Smart defaults mean you never have to think about the plumbing.
Share
Send a link, friends tap to join
Drop the invite into any messenger. Friends open it and they’re in — no account hunting, no friction. The link works whether or not they have the app yet.
Ding
Tap to bump the score and ping everyone
Every trigger bumps the score and fires a notification — with its own custom sound — to everyone subscribed. A shared scoreboard crossed with a playful ping.
Three glanceable surfaces
Widgets
Home- and lock-screen widgets keep the current score a glance away. Tap one to trigger without opening the app.
Live Activity
A Live Activity and the Dynamic Island follow the action as it happens, updated live by push.
Canvas
A shared canvas everyone can draw on together — append-only, so no one ever clobbers anyone else’s strokes.
The social loop is always free
Creating events, joining friends, the default sound library, widgets, the Live Activity, and a canvas are free forever. Pro — for making your own custom sounds and text, extra canvases, and advanced tools — comes as a monthly subscription or a one-time lifetime unlock, whichever you prefer. And receiving is always free: your friends hear your custom sounds even if they never pay a cent.
