We build applications for iOS and Android — with privacy at the core.
Opportune Labs LLC designs and develops consumer software for people managing their health. No accounts, no sign-ins, no data harvesting — the most sensitive data you have stays on your device.
iOS Development

Android Development
Bringing our applications to Android so every user gets the same privacy-first experience, whatever device is in their pocket.

Opportune Labs is founder-led and independent — every function above reports to, and is driven by, the founder's single standard: software we'd trust with our own health data.
Opportune Labs started with a simple frustration: no health tracker handled the whole picture — the doses, the supplements, the trends — without demanding an account and your data. So we built one, and built the company around the idea that health software should answer to its users, not to an advertising model.
We design and develop our applications end to end: native iOS and Android engineering, product design, and support, all under one roof — and every feature is shaped directly by the people using it.
The name comes from the Greek kairos: the opportune moment. Most of health is showing up at the right time — the dose on schedule, the reorder before the bottle runs dry. Our software exists to catch those moments.
