Superpower and ONU share some real common ground: both talk about biomarkers, both use AI to build a personalized plan, and both frame biological age as a meaningful longevity metric. The core difference is structural — Superpower is a membership built around its own annual lab panel; ONU is an ongoing app built around aggregating data you already have.
Detailed comparison
If you're choosing between the two rather than using both, start by being honest about which habit you'll actually keep up: an annual test cycle with a care team you occasionally message, or a daily habit of checking a score and short explanation. Neither is inherently superior — the one you'll actually engage with consistently is the one that will deliver real value, and there's no rule that says you can't do both if budget allows.
Worth being clear on ONU's own structure too, since it isn't a single flat price: the app is free to start and connect your existing device to, the full interpretation-and-improvement layer requires the ONU Pro subscription ($16.99/mo or $149.99/yr, started inside the app after download), and the ONU Bracelet is available afterward for an extra $99 if you want the most accurate, dedicated version of the experience.
