Bio Optimizer helps you see what happens between lab visits. Save blood panels, sync daily rhythm from Apple Health or Oura, and follow one private Optimizer Index on iPhone. Core scoring on device; optional iCloud—we don't warehouse your health data on our servers. Wellness education only, not medical advice. iOS 17+ · US App Store · feedback welcome.









How does the Optimizer Index actually get calculated when you pull in data from Apple Health and Oura together, since the metrics from each don't really line up one-to-one?
@minec9mv
Great question — they don’t line up one-to-one, and we don’t pretend they do.
1) One calendar day first
The Optimizer Index is built on your local calendar day. Apple Health and Oura are merged onto that spine. Oura’s own “activity day” (04:00-based) can lag calendar midnight, so early morning we may show Preparing until today’s Oura daily rows align — we’d rather be honest than publish a misleading score.
2) Metric-by-metric merge (not a single source)
When both are connected, we combine signals per metric, e.g. HRV and sleep lean Oura when present; steps use a credibility guard (e.g. max of both when both look sane, fallback rules when the ring or phone was clearly left behind). Missing fields fall back to whichever source has data — we don’t force duplicate columns into one fake number.
3) Bio → Optimizer Index
Wearable merge feeds a Bio pillar (rhythm/recovery-style signals). Blood from your latest lab anchors the story; Mind and Daily add optional context. The top-level Optimizer Index is a weighted blend of those pillars (blood-weighted, with reliability logic when a panel is stale) — wellness context, not diagnosis.
4) On-device
All of this runs on your iPhone; we don’t warehouse your health records on our servers.
If you’re on Oura + Health together, I’d love to know which metric feels most “off” day to day — that’s exactly the feedback I’m looking for.
@minec9mv Thanks, Mine — really appreciate you taking the time to ask. Hope the breakdown helps, and I’d love to hear how it feels if you try the Oura + Health path.
How does the Optimizer Index actually get calculated if core scoring happens on device with no server warehouse to pull population baselines from?
@hasanirantcwnt
Great question. We don’t pull population baselines from our servers — there is no health warehouse.
The Optimizer Index is computed on your iPhone from your data: your latest blood panel anchors the story, and daily rhythm comes from Apple Health and/or Oura merged onto your local calendar day. As you add panels and days of wearable history, your personal context deepens; we’re not scoring you against a cloud cohort.
Wellness education only — not diagnosis. Happy to go deeper on any pillar if useful.
finally an app that doesn't ship my bloodwork off to some random server, and the optimizer index actually reflects how off my sleep was last week
@lknursafalge6s
Thank you, İlknur — really glad the on-device privacy and the index read matched your week. If anything feels off on the Oura/Health path, I’d love to hear it.
Curious how the Optimizer Index actually weighs the blood panel data against the daily rhythm metrics from Apple Health and Oura, like is it a fixed formula or does it adapt over time as more data comes in?
@cennetmdmk
It’s a defined on-device formula, but the inputs evolve with your data.
Blood weight reflects your saved lab snapshot (and reliability logic when a panel is stale). Bio/Mind/Daily layers update as new wearable days and habits come in — so the mix can feel more “yours” over time, but we’re not doing opaque cloud ML on your records.
If you try Oura + Health together, I’d love to hear which part feels adaptive vs still too static.
Love that the Optimizer Index runs on-device and iCloud is opt-in. Feels rare to see a health app in 2024 that treats the data like yours instead of theirs.
@ayegl433435
Thank you, Ayşegül — that’s exactly the architecture we wanted: core scoring on your iPhone, optional iCloud in your Apple account, and no company-server warehouse of lab or wearable health records.
Really appreciate you noticing. If anything in Settings → iCloud & Data or Wearables & Sync is unclear, tell me — I’m the builder.
Love that the Optimizer Index runs on device first. Treating health data with that kind of restraint is rare and honestly the main reason I'd trust it enough to actually use it daily.

Privacy is one of the choices we designed the app around. We could anonymize and warehouse trends to help us improve faster — we deliberately didn’t. User sovereignty comes first; we focus on on-device performance and features instead.
