Three steps to a louder race.
Plan your race, invite your cheer squad by text, email, or QR code — then go the distance. Every voice plays automatically, phone-free.
Map your race
Import the course or sketch it right on the map — even the swim. GimmeSum drops cheer spots along the way: the start, the markers, the wall, the finish.
Your squad claims their spots
Each friend picks a spot on your course — first come, first served — and records 30 seconds of their real voice. No app needed: the invite link records right in any browser.
Voices find you out there
On race day your Apple Watch plays every cheer out loud, right on cue. Mom at the start. Your coach at mile 5. Everyone at the finish.
The invite link becomes a live broadcast.
Flip one switch at the start line. From that moment until you cross the finish, your race is live for everyone you invited — and the couch can talk back.
🔴 The tap on every squad iPhone
The moment you start, your people get the word: on the course! One click on the same invite link and they're watching your dot move — live map, pace, a projected finish.
⚡ Cheers land in seconds
Anyone watching presses Cheer now, records, and sends. The voice plays out loud on the course moments later — from any phone or browser, anywhere on Earth.
🎁 The day is kept
Every voice that reached you out there is saved with the race — Live from race day, your audio keepsake of the morning, kept for good.
It trains with you, too.
The months before the race are where the work lives — so GimmeSum learned to coach the whole season, not just the morning.
Training programs
Pick your race and get a week-by-week plan that counts down to the start line — long runs, rides, swims, and brick days for triathlon builds.
Rolling seasons
No race on the calendar? Train anyway. Set your own weekly dial for each sport and the weeks climb gently from where you actually are — every fourth week a lighter one. Sign up for a race and your season hands off its fitness to the new build.
Intervals, spoken
Structured reps with rests that end on the clock — your Watch speaks each rep and each rest. In the pool, the wall taps your wrist instead: swim intervals, by lengths.
Records worth keeping
Your Watch celebrates the moment a run or ride becomes your longest ever. Manual laps with the LAP button, spoken and charted. Ghosts of your best day on every saved route.
Life-proof plans
Take a sick week off guilt-free. Move any workout to another day. Rebuild a race plan from today's fitness — the weeks you've done archive as a keepsake.
Yours, everywhere
Programs back up to your own iCloud — a new phone picks up the plan right where you left it. No accounts, no server of ours holding your life.
One race. One Watch session. Voices all day.
Sprint, Olympic, 70.3, or 140.6 — GimmeSum treats the whole day as one race. Water lock through the swim, the TRANSITION button between legs, and cheer spots everywhere — including T1 and T2, the two moments every triathlete earns a voice.
The live map draws all three courses, pins each cheer on its leg, and shows your people which sport you're in — the moment you're in it. A goal time wakes the Hare, a quiet pacer on your wrist that knows a swim minute isn't a run minute.
Have a look around.
Straight from the app — swipe through.
Be there, from anywhere.
Someone you love is training for something hard. Thirty seconds of your voice plays out loud when the course gets quiet and the legs start arguing. No app, no account, no setup — the invite link records right in the browser, from any phone or computer on the planet.
A serious tracker first.
Everything you'd demand from a daily driver — on Apple Watch or iPhone alone. The cheers are the soul; this is the spine.
Simple, like it should be.
