For Developers

Build Health Apps That Give Users Data Agency

Get a production health data backend with Programs, insights, and compliance — so you can focus on the experience your users love.

LLIF provides the legal foundation for participant data — enforcing integrity, agency, privacy, and safety across work involving OpenLife Cloud and Best Life App. Developers build on OpenLife Cloud infrastructure with LLIF's nonprofit governance as the foundation.

Why Build on LLIF

Your App + Our Foundation

Most health apps trap users in tiny, disconnected data silos. When your app builds on LLIF, you're offering something different: a unified, longitudinal data lake that belongs to the user — not to you, and not to us. That's a value proposition no for-profit backend can match.

Programs from the LLIF marketplace — prebuilt value for your users
102 API endpoints — events, analytics, nutrition, environment, users
Multi-source sync: Apple Health, Google Fit, Fitbit
Environmental enrichment with 25+ metrics per event
Insights engine: correlations, trends, predictions
No competing products — LLIF is infrastructure, not an app

Best Life App: The First App on OpenLife Cloud

Best Life App — built by Best Life Inc. on OpenLife Cloud
