Healthy routines stick when your friends are watching
Wellu wanted to enter the consumer market with a simple idea: healthy routines stick when your friends are watching.
For that it needed a real app on both stores, with subscriptions, notifications that do not annoy, a leaderboard no one can game and a lean operation in which a small team keeps up with thousands of check-ins. On a tight deadline.
A complete app, with subscriptions and gamification, that a small team can run
We built the entire product: app, backend, admin panel and the AI that supports the operation.
- Native app for iPhone and AndroidSocial login, challenge feed with photos, likes, comments, invite links and a final leaderboard.
- Gamification with fair rules67 activities across 8 dimensions, two leaderboards, scoring limits, auditing and moderation.
- Wellu+ subscriptionIntegrated with the App Store and Google Play, with a free trial and a well-designed free plan.
- Workout integrationsApple Health, Health Connect, Samsung Health and Strava, always with the person confirming.
- Run from the admin panelFeatures rolled out gradually, push campaigns with frequency caps and updates that skip the store review.
- Lean infrastructureCloud that scales from zero with usage, with budgets and alerts, all described in code.
AI in the operation, a person in control
On the check-in photo, the AI compares the image with examples from the team and suggests switching the activity when something does not match. The person decides, and if the AI fails the check-in goes through normally.
In the admin panel, the AI writes the daily summary from real data, answers questions from the team in plain language, groups cancellation reasons and proposes message variants. In support, an assistant answers first and hands sensitive cases to a person.
On both app stores in about four weeks
From the first commit to both app stores in about four weeks, with subscriptions, gamification and AI helping a small team run the product.
