RundveeNet

A livestock-management application designed to be used in a barn with one gloved hand. Offline-first, syncs the moment the WiFi returns.

Problem

Dutch livestock farmers recorded treatments, calvings, and checks on paper, then copied them into an aging SaaS in the evening. Half the data was late or lost. Competing apps were designed for a desk, not a barn.


What we did
  • On-site discovery in two working farms with usage diaries
  • Product design tuned for a large touchscreen and a gloved hand
  • React Native (Expo) app for iOS and Android from one codebase
  • Offline-first sync layer on Supabase, tested with 24h of no network
  • Submission to App Store and Google Play

Approach

Offline-first by default — WiFi in a barn doesn't exist. Writes happen locally and sync when the network comes back, without loss or duplication. Permissions are shaped by role — barn worker, manager, owner — each seeing exactly what they need. We tested the UI with actual gloves on a tablet, not a mouse.


Stack
  • React Native (Expo)
  • Supabase
  • Postgres
  • Offline-sync
  • APNs / FCM

Outcome
  1. 01Published on App Store and Google Play from one codebase
  2. 02Daily paperwork dropped from ~45 minutes to <10 minutes per farm
  3. 03Offline sync queue survives 24h with no network, no loss, no duplicates
  4. 04Shipping new features on fortnightly sprints since launch

Faster to open the live site than to read about it. Public, no login required — have a look around.
