We Built a Bike Security App in 24 Hours
How Emil and I built LockHere at the Techsylvania hackathon — a mobile app that alerts you when someone touches your bike.
Emil and I entered the Techsylvania hackathon last week. 24 hours, connected devices theme. We built LockHere — detects motion around your bike, sends you a real-time alert with its location. Simple idea. Bikes get stolen in Cluj all the time.
Rails backend (obviously), Here maps for location, and whatever else they gave us — Telegram, IBM Cloud, Snips. The code was terrible but it worked. Won a special prize from Here, got a trip to Krakow for another hackathon.
Honestly the best part was just building something without process. No tickets, no standups, no PR reviews — just two people trying to ship before the timer runs out.
The Wolfpack team also wrote about this on their blog.
