What's New in January 2026 We kicked off the new year by tidying up a few things (because our New Year's resolution was to be more organized): - Swipe left to remove sessions: Finally, an easy way to break up with sessions that didn't work out - Battery optimization alerts: We'll now let you know when your phone's battery settings are secretly sabotaging your runs - UI polish: A few visual touch-ups, because even apps deserve a fresh start in January If OnTracx is helping you hit your goals (or if you have ideas to make it even better), we'd love to hear from you. Email: support@ontracx.com Thank you for running with us – one managed step at a time.
