New version 1.5.9 β†’ 1.5.11

What's New **Ranked Challenges: Every Kilometre Counts** No target. No cap. This month's challenge is a straight race for the most kilometres β€” and your live rank sits right on the card, so you always know exactly who's ahead and by how much. Time to chase them down. **Never Miss an Update** A newer SUB on the App Store? You'll see a gentle banner the moment it lands. One tap to dismiss, and it stays out of your way until the next release. **Running Fitness, Right Where You Left It** The θ·‘εŠ›εˆ†ζž tab now remembers your place and the times you typed, so you can jump back in without starting over. **Coupons, Redeemed in One Tap** Show your code, staff tap confirm, done. And if a code times out, the screen now tells you and lets you try again. **Sharper Track Calendar** The sports ground calendar stops at the last published date instead of paging into empty months. **Rock Solid** Brief connection hiccups no longer show up as crashes. SUB now requires iOS 15 or later.
