Better Layta than never

Your gut data. Your device. Your rules.

Layta is an open source app and toolkit for abdominal sensor patches, including Suna. No account, no cloud lock-in, no subscription. Built by volunteers at a non-profit, licensed so it stays that way.

AGPL-3.0
Local first
No telemetry
Non-profit

Some data is too personal to rent back from a company.

Gut sounds, meals, sleep and bowel habits say a lot about a body. That record should not depend on one vendor's servers, pricing or survival.

100% open

Protocol docs, signal processing, models and apps are all public. Every algorithm that turns sound into a score can be read, tested and challenged.

Independent

No investors, no ads, no data deals. Layta is run by a non-profit and funded by donations and grants. Nobody can sell the project, or you.

Yours to keep

Raw recordings and derived data stay on your phone or your own server. Export everything in open formats, any time, without asking.

How it works

01
Pair your patch
Layta talks to the patch directly over Bluetooth Low Energy. No vendor account in the middle.
02
Process on device
Bowel sound detection, motion and temperature analysis run on your phone. Models are open and reproducible.
03
Log and learn
Tag meals, stress and sleep. See how they line up with your gut activity over days and weeks.
04
Share on your terms
Sync to your own server, export to Apple Health or Health Connect, or hand a CSV to your doctor. Or keep it all offline.

What you get

Meal correlation

Log what you eat and see how your gut responds in the hours after. Patterns, not diagnoses.

Daily gut score, explained

A daily summary of digestive activity, with the formula published next to the number. No black box.

Bowel activity timeline

Continuous acoustic tracking turned into a readable timeline. Raw audio kept only if you choose to keep it.

Overnight tracking

See what your gut does while you sleep and how it relates to rest.

Open data formats

Everything exports to documented formats. Researchers and tinkerers can build on top. A self-hosted sync server runs in a single container.

Built for interoperability

We document each supported device's Bluetooth protocol in the open, so any app, not only ours, can read your own data.

Suna patches are announced to ship in 2027. Layta support follows once hardware is available to test against. Until then we develop against our own open reference patch. Whenever theirs lands, Layta will be ready, source code and all.

Better Layta than Suna

They say better late than never. With your gut data, sometimes later and open beats sooner and closed.

Questions

Is Layta a medical device?

No. Layta is wellness and research software. It does not diagnose or treat any condition. Talk to a doctor about symptoms.

Is Layta affiliated with Suna Health?

No. Layta is an independent project with no relationship to Suna Health or XAICARE LTD. Suna is a trademark of its owner, used here only to describe compatibility.

Can I read my own device with a third-party app?

We document protocols for interoperability so owners can access their own data. We do not ship vendor firmware or bypass security on anyone else's device.

Does it work on iPhone and Android?

That is the plan. The app targets both, plus a desktop viewer for exported data.

Where does my data live?

On your phone, encrypted at rest. If you enable sync, it goes to a server you choose, encrypted in transit. There is no Layta cloud.

How is the project funded?

Through individual donations and public interest grants, managed by the non-profit. No investors and no advertising.
