Passive Gut Health Monitor
Throne One Smart Toilet Sensor
The first toilet-mounted sensor to turn every bathroom visit into continuous gut health, hydration, and urinary data — no samples to collect, no appointments required. Think of it as a Whoop for your gut, installed in the one place that's already generating the data.

Primary signalsStool consistency, color, frequency
Hydration markersUrine color + concentration
Urinary functionFlow patterns, frequency
Bristol Scale scoringAutomated per session
Trend detectionDays, weeks, months
High score for novelty and continuous capture — no other DTC device offers passive daily gut data. Moderate deduction: no microbiome sequencing, no metabolite or inflammatory marker detection. Throne measures outputs, not root causes.

MethodologyComputer vision + AI (2 MP downward camera)
Clinical backingPhysician advisory; Bristol Scale established
Lab accreditationNot applicable (no sample analysis)
Published Throne studiesLimited as of 2025
GI doctor endorsementDr. David Rubin, Univ. of Chicago
Bristol Stool Form Scale is well-validated; hydration estimation from urine color has reasonable research support. Deductions for limited peer-reviewed studies on Throne's specific AI accuracy and no independent lab validation of output readings.

App insightsGut score, hydration score, daily trends
Food tracking integrationPhoto meal log to correlate intake
Medication trackingYes — flag med changes and see gut response
Pattern alertsYes — flags shifts and irregularities
Clinician exportYes — shareable data for provider visits
Strong marks for integrating food, meds, and passively captured data into one view — useful for GLP-1 users, IBS management, and pre/post-colonoscopy tracking. Deduction: correlation-based insights, not diagnostic. Still no direct "here's what to change" recommendation engine.

Device price$399.99
Membership$6/month (required for full insights)
Annualized cost$399 + $72/yr = ~$472 yr 1
Per-session cost~$0.04/session at 3x/day
Multi-user valueUp to 6 phones — spreads cost in households
Value math:
Yr 1: $399.99 device + 12 × $6 = $471.99
Ongoing: $72/yr for continuous daily monitoring
Comparable wearables (Whoop, Oura) run $299–$499/yr with no device cost. Throne's ongoing cost is notably lower once device is amortized. HSA/FSA eligibility can reduce effective cost by ~30%.

SetupClip-on, no plumbing — ~5 min
Data captureFully automatic, phone detection trigger
Battery life~30 days, USB-C charging
ConnectivityDual-band Wi-Fi + Bluetooth 5.1
Privacy designDownward-facing only; bank-grade encryption
NightlightMotion-activated — yes, it has that
Best-in-class frictionless capture. Zero behavior change required — the data just accumulates. Privacy design is thoughtful and should be enough for most users. Minor deduction for early-stage software maturity and the fact that phone proximity is required to trigger capture (missed sessions if phone isn't present).
Why your gut data matters more than you think
The average person never looks at their gut health data because collecting it is unpleasant and manual. Throne solves a real data gap: 70% of immune cells live in the gut, GLP-1 medications cause significant gut changes most users never track, and IBS affects ~15% of adults with no passive monitoring option. This is the first device to collect that data at scale without asking anything of you.
Strengths & limitations

MYM verdict
"If you're on a GLP-1, managing IBS, or simply want to understand what your gut is actually doing day to day, Throne is the most frictionless gut data source that exists. It's not a diagnostic — but as a pattern tracker, it fills a gap nothing else does."
