"I had my husband record something for mile 20 of my marathon. I had no idea what he said until I got there. I ugly-cried and PR'd in the same minute. CHIRPSTR is something else."

"I coach a running group and we all use CHIRPSTR now. I record a quick pep talk the night before our long run and it hits different when it plays mid-stride at mile 8."

"I'm a 5K mom who never thought I'd run more than a mile. My daughter recorded a message for me. I didn't stop. I kept going just to hear what she said next."

FAQ

Got questions?

Everything you need to know about CHIRPSTR.

What exactly is CHIRPSTR?
CHIRPSTR was built to be a motivational and community-driven app designed to connect the user directly to their family, friends, and coaches. Your community loads your account with voice message recordings, that we call Chirps. Then during your run, those messages play through your headphones right in the middle of your music at timed intervals. It's like having your entire support crew in your pocket, with you every step of the way.
Do my supporters need to download anything?
Nope. You share a unique link with your supporters and they record their message directly in a mobile browser. No app download, no account required. Super user friendly so even grandparents can get in on the action.
When do chirps play during my run?
In training mode, we give you control by toggling the intervals of how often you hear your chirps. In Race Mode, your device's GPS will trigger mile-specific chirps. Kick Mode plays chirps every 5-seconds to help power you through the rough spots!
Will chirps interrupt my music?
During activities, CHIRPSTR will temporarily turn down your current music / audio, then plays the voice message clearly. Once completed, your music picks right back up, keeping you motivated and in the zone!
How long can a chirp be?
Up to 30 seconds. We think that's long enough to say something meaningful, but short enough to keep you moving without breaking focus / your runner's high.
Is CHIRPSTR only for marathon runners?
Not at all. CHIRPSTR works for any run or activity, be it a 5K, half marathon, long training run, or even those tough workouts. If you've got people who want to cheer you on, CHIRPSTR gets their voices in your ears.
Is CHIRPSTR free?
CHIRPSTR has a free tier that lets you get started with training mode, unlimited chirps saved for 30-days, one custom playlist, and custom interval scheduling, CHIRPSTR Pro is available for just $0.99/month or $9.99/year. You get access to evevything in free PLUS the infamous Race AND Kick Modes, unlimited playlists, and your chirps get saved for a full year!
Does it work with my headphones?
Yes. CHIRPSTR works with any headphones or earbuds your device supports, AirPods, Bluetooth headphones, wired earbuds, you name it.
What happens to my voice recordings?
Your chirps are stored securely and are only accessible to you. We don't share them, sell them, or use them for anything else without your permission. See our Privacy Policy for the full details.
Is CHIRPSTR available on Android?
Right now CHIRPSTR is iOS only. Android is on the roadmap — drop us a line at [email protected] if you want to be notified when it launches.
