The mission
Why this exists.
Community support still lives in chaotic group chats — “please like this,” “watch this,” “share before tonight.” Supporter exists to turn that noise into a campaign: one list of actions, points that reward people who show up early, and a leaderboard the group can actually see.
Inside the build
Thought through, end to end.
5 highlights
Time-Based Points Decay: Built per-link scoring with optional interval decay and floors so early supporters earn more while late joins still count.
Live Progress & Leaderboards: Designed campaign and group rankings that update with completions, plus a cross-group Home feed of next actions.
Push Notifications: Integrated campaign alerts so members get notified when a group publishes new work, with deep links back into the campaign.
Offline-Aware UX: Cached group and campaign data with persistent tabs, light/dark themes, and clear offline, empty, and error states.
The hard parts
Constraints I designed around.
The features that look effortless were the ones that fought back.
- 01
From scattered DMs to a campaign
The obstacle
Admins had no single place to assign Instagram, YouTube, and web actions with roles, invite codes, and a shared checklist.
How I solved it
Engineered invite-code groups with admin/member roles and multi-link campaigns so every member sees the same work, in order.
- 02
Fair points when people join late
The obstacle
A flat score lets last-minute taps equal the people who carried the launch — which kills the reason to show up early.
How I solved it
Built per-link scoring with optional interval decay and a floor — early supporters earn more, late joins still count, and group totals never go below zero.
- 03
Live progress that survives a dead connection
The obstacle
Rankings and “do next” go blank the moment the network drops, and tab switches reload everything.
How I solved it
Kept main tabs mounted, cached group and campaign data, and wired FCM alerts with deep links so members get new work even when the app is closed.
