Hey. I’m Sondre — an Olympic pole vaulter who had zero experience in app development, but I taught myself how to build an app because I was struggling to follow my friends' dating lives after graduating college. The group chat was chaos — screenshots, nicknames, mixed signals, and constant “wait, who’s that again?” So I built ROSTR — a Strava + Group Chat style app for dating: ✅ Track your “roster” with real statuses like Active, Fading, or Ghosted ✅ Log date details with notes, ratings, red flags ✅ Share updates in a private feed just for your trusted friend circles ✅ Get advice, comments, and polls from your crew I built this while training and competing as an olympic athlete — it started as a side hobby and now it's live on the App Store 🙌 Would love your thoughts. What features would YOU want to track in your dating life or your friends’? Thanks so much for checking it out! — Sondre
