The challenge

Co-Exist Australia runs conservation days with young people across the country: tree plantings, beach clean-ups, restoration work, held by local collectives. Sign-ups lived in spreadsheets and group chats, attendance was counted by hand, and nothing held the totals afterwards.

What we built

A mobile app on iOS and Android. A young person joins a local collective and sees the collective's next event. On the day, they check in with the code the leader shares, and the leader logs what the day produced: trees planted, rubbish removed, hours given. Those numbers roll up into a dashboard the whole collective can see.

How we worked

One codebase ships the same app to both stores off a single Ecodia pipeline, so a fix reaches iPhone and Android the same afternoon.
