Built by pilots who got tired of guessing.
We made the planner we wanted to have: one that tells you whether the mission fits the battery and the weather before you take off, not one that confirms it after you didn't make it home.
Our mission
RangeSight was built around one idea: pilots should fly with the numbers, not a hunch. Working out your real flight range shouldn't take spreadsheets, a separate weather app, and mental math at the launch point. RangeSight folds live weather, battery chemistry, payload weight and aircraft performance into a single range estimate you can plan against, computed on your phone. It runs on iPhone, iPad and Android, and it's used by everyone from weekend flyers exploring a new spot to operators on jobs where getting the range wrong isn't an option.
Why we built it
As pilots ourselves, we got tired of guessing whether the next leg was a good idea. Manufacturer range figures are best-case numbers from conditions that almost never exist in the real world. Wind, cold batteries, altitude and payload all quietly eat your usable range, and most pilots have no reliable way to fold any of that into a plan. We wanted a tool that did the math for us. The on-device RangeIQ engine takes wind, temperature, humidity, altitude, payload and battery health and gives you a number that reflects today, not a spec sheet from a sunny day at sea level.
How RangeIQ works
RangeSight runs two physics engines built on the same model. RangeIQ runs on your device and draws the Range Analysis Map: a wind-shaped safe round-trip envelope from a launch point, stretched downwind, pulled in upwind, never a flat circle. RangeIQ+ runs in the cloud and powers the Mission Analysis Map, which takes a whole planned route and checks it leg by leg, with a return-home check at every waypoint. The same RangeIQ+ engine is also available to developers as an API. See it in the app ยท For developers
We say what the model does, and what it doesn't.
RangeIQ and RangeIQ+ are physics-based models with a provisional patent filed, and they ship in a real consumer app, but we don't claim a validated accuracy percentage, and we don't call it “certified” or “guaranteed.” It's decision support, with a reserve built in. That honesty is the product, too: a planner you can trust is one that tells you the truth about its own limits.
