The Instrument

Not Just a Forecast.
A Reality Report.

Every feature built for professionals who make field-critical decisions based on verifiable, high-fidelity environmental data.

Decision Hub

Actionable intelligence that converts raw weather data into specific recommendations. Know exactly when conditions shift.

Reality Index

A proprietary 0–100 confidence score. Instantly know when models disagree and data reliability is compromised.

Activity Suitability

Professional scoring matrix for Cycling, Hiking, Gardening, Photography, Running, Fishing, and Stargazing.

Astronomy & Light

Precise twilight phase calculations, Golden/Blue hour windows, and moon data for professional photography and field ops.

Health & Hazard

Real-time health advisories including migraine risk from pressure trends, frost alerts, and automated storm warnings.

AI Insights

On-device AI that synthesizes conditions, forecasts, and activity context into plain-language recommendations you can act on immediately.

The Engine Room

Data Integrity, First.

A weighted consensus model that doesn't simply average data—it interrogates it.

01

Weighted Consensus Model

Multi-source data blending across NWS, MET Norway, IEM/AgEBB, and personal weather stations. Sources are weighted by station fidelity and hardware voltage standards—not simple averaging.

02

AI Insights

On-device intelligence that reads current conditions, forecast trajectories, and your activity context to generate plain-language briefings. No cloud round-trip required—your data never leaves the device.

03

Adaptive Alert Engine

Real-time monitoring that triggers contextual alerts—frost warnings, storm cells, health advisories—based on multi-source consensus, not single-provider thresholds.

04

Dynamic Source Blend

Granular transparency into how each source—NWS, MET Norway, USDA SCAN, your PWS—contributes to the final reported value. Full provenance on every data point.

Hardware Integration

Your Environment, Anchored by Professional Hardware.

Direct API handshake with Ecowitt and Ambient Weather gateways. DewLogic connects to your Personal Weather Station at the hardware level, bypassing sanitized consumer networks for raw, high-fidelity sensor data.

Meet the Developer

Travis Winegar

“I built DewLogic because weather apps shouldn’t be entertainment products. They should be instruments. Every data point in DewLogic is traceable to its source, every forecast is weighted by station fidelity, and none of it leaves your device. I run this project under MOMUS DEV, LLC, and my only stakeholder is you.”

The “Solo” Advantage

“My ‘smallness’ is a security feature. As a solo developer, I’m not beholden to advertisers or data brokers. I answer only to you.”
