DewLogic is LIVE on iOS!
DewLogic is officially available on the iOS App Store!
Built with a local-first philosophy, DewLogic aggregates multiple weather sources into a clean, sovereign interface designed for accuracy and privacy. No ads, no tracking just the data you need.
DewLogic has become my new weather app
I started testing as a favor but I didn't really have any issue with the weather apps that were already installed on my phone. Fast forward and I've actually uninstalled the other apps, moving exclusively to DewLogic. It has everything I might need, current conditions, future forecasts, radar, etc but a lot of apps do that. DewLogic presents it in a manner that feels more intuitive to me and I appreciate that. It's very customizable and has proven to be pretty accurate with a lot of the predictions it offers up in the insights tab.
From weather data to decisions
From weather data to decisions
"72 F and partly cloudy" is data. It is not an answer to the question you actually asked.
The question you actually asked was one of these:
Should I spray the orchard today?
Is tomorrow good for a long run?
Will the wedding ceremony be comfortable outdoors at 4 PM?
Is it safe to take the boat out Saturday morning?
When is the golden-hour light going to be worth driving an hour for?
Should I cover the tomatoes tonight?
Is this a migraine-risk day for my kid?
None of those are answered by a temperature and an icon. They're answered by a small model that takes the weather context and applies a domain rule set. That's what the DewLogic Decision Engine is.
The modules
We ship several first-party decision modules, each with its own scoring logic:
Activity scoring. Running, cycling, hiking, tennis, golf, pickleball, kayaking, skiing, dog walks, and more. Each activity has a different comfort envelope and different blocking conditions.
Agriculture. Spray windows (wind, humidity, rain proximity), growing-degree-day accumulation, frost risk windows, evapotranspiration, leaf wetness duration.
Hazard analysis. Heat index, wind chill, lightning proximity, flash flood risk, wildfire smoke, ice events.
Health advisory. UV exposure, pollen count, air quality, pressure swings (migraine risk), humidity effects, user-configurable sensitivities.
Marine analysis. Small craft advisory thresholds, sea state, wind direction vs. fetch, fog risk.
Photography planning. Golden hour timing, cloud cover quality at sunrise and sunset, atmospheric clarity, storm chase windows.
Recommendation generation. Combines the above into a ranked list of "good for" and "avoid" suggestions tailored to the day.
