What's New in Kardiacs

26.9.2

September 10, 2026

• Offline maps for anywhere on Earth: search for a place — Kyoto, Nairobi, Bogotá — and take its map with you, instead of only the ground that happened to be on the list • Download as much of the map as you like — the monthly and four-at-once limits are gone; every area shows its size before it starts, and a swipe gives the space back • Chat & Notes, in Settings: every notepad and every group conversation from every ride in one list, to read, export or delete — and notes are per ride now, so a ride opens on a blank pad instead of on March's gate code • Your ride is written down as it happens. A flat battery, a crash, or iOS reclaiming the app in your pocket used to throw away everything since you pressed start; now the ride is waiting when you come back • Fitness History draws the shape of the ride: every activity has its own map, read from the file on your phone • Send a ride to a coach or a club as a FIT file, with or without the track — the switch is off unless you turn it on • Sixteen more languages: Simplified and Traditional Chinese, Korean, Russian, Arabic, Hindi, Indonesian, Turkish, Vietnamese, Thai, Polish, Dutch, Ukrainian, Swedish, Irish and Tibetan — twenty-three in all • Any rider in a group can ask for any stop now — a café, a bike shop, anything, not just water and a restroom — and when the leader says yes it goes on everyone's route, not only on theirs • Choose whether a Wi-Fi Aware pairing lasts the ride or is remembered for good, in Preferences → Wi-Fi Aware Pairing • The group has its own Lock Screen card when no ride is using the lock screen, and unmuting from there works • A voice link that has quietly stopped carrying anything is dropped rather than counted as healthy — the group screen no longer says all is well while nobody can hear you • A new bike arrives in the Garage with its gear already on it, and the kit editor takes more than one change before you save • Cycling routes read the sign rather than the class: a 25 mph secondary or a 20 mph tertiary is priced like the calmer road it is • Bug fixes and performance improvements

Love this app.

This app is super well thought out and covers bases I didn’t even think of. I love being able to get directions offline. I also love that it’s a free app for so much.
