It is the same RaceLog+ either way: one free account, one race history, synced everywhere you open it. Choose whatever is easiest right now, you can add the others later.
Free on Google Play. Android 7.0 or newer. You can create your account inside the app, no need to visit the site first.
Submitted and waiting on Apple review. The moment it is approved this button goes live. Until then the browser version works perfectly on iOS: open the site and add it to your Home Screen.
Nothing to download. Works on any phone, tablet or computer, and it is the full app, not a cut-down version.
Log a race on your phone at the finish line, add the photos from your laptop that evening. It is one profile, not three.
This link sends every person to the right place for their device, so you only ever have to share one address.
