Calculate your drone's real flight range, not factory specs. Powered by the RangeIQ™ on-device physics engine that accounts for wind, weather, payload, battery health, and more.
iOS planned.
Mission planning that works where you work.
Plan missions with precision across any terrain.
Real-time battery range visualization for safer flights.
What is RangeSight?
An Android drone flight planning app powered by the proprietary RangeIQ™ physics engine. It calculates real-world drone range by accounting for wind, temperature, humidity, altitude, payload weight, battery health, and dozens of other environmental and mechanical factors, all computed entirely on-device.
Now on Google Play | Free & PRO: Your range isn't a circle. Wind pushes you further downwind and holds you back upwind. RangeSight shows the real shape of your flight envelope with wind-deformed directional range rings calculated at 360 points.
On-Device Physics Engine
Every calculation runs on your phone. No internet required. No cloud processing. Your data never leaves your device. Results in under a second.
Wind-Aware Directional Range
Range rings deform based on wind direction and speed. See your actual flight envelope: further downwind, shorter upwind, calculated at 360 directional points.
7-Ring Battery Safety System
Seven color-coded range rings show exactly how far you can fly and still return safely at different battery reserve levels, from 25% reserve down to one-way maximum.
Six Core Features
Everything you need for real-world flight planning, accessible from one interface.
Live Weather Data
PROOne-tap real-time weather from your GPS location. Wind speed, gusts, direction, temperature, and humidity, all color-coded against your drone's safety limits (green/yellow/red).
Flight Range Calculator
The RangeIQ™ engine combines wind, temperature, humidity, altitude, battery health, payload, and gust penalties into a single accurate prediction. Configurable battery %, cycles, cruise speed, hover time, and fine-tune calibration.
Interactive Map
4 map styles (Street Day/Night, Satellite, Terrain). Wind-deformed range rings, draggable map pins, animated wind direction arrow, weather overlay, and collapsible legend. Full offline support with downloadable tile packs.
31 Drone Profiles
The most comprehensive library available. 5 manufacturers: DJI (23), Autel Robotics (4), Parrot (2), Skydio (1), Freefly (1). From the 249g DJI Mini 4 Pro to the 11.5kg Freefly Alta X. Every profile tuned with manufacturer specs.
Offline Maps
PRODownload regional map tile packs organized by country and state for fully offline field use. 100% local computation. The app never needs internet for core functionality. Manual weather entry available to all users.
Payload & Safety
PROFull payload weight modeling with drone-specific efficiency curves. Battery cycle degradation tracking. Fine-tune calibration from real test flights. Color-coded weather safety thresholds per drone.
7-Ring Battery Safety System
Seven color-coded range rings show exactly how much battery you'll have for the return trip at any distance and direction.
31 Drone Profiles, 5 Manufacturers

Powered by RangeIQ™: The Physics Engine for Drone Flight
RangeSight's outputs aren't hand-wavy estimates. They're produced by RangeIQ™, the proprietary on-device physics engine that processes wind, temperature, humidity, altitude, battery health, payload weight, and dozens of other variables through a multi-factor model.
RangeIQ runs entirely on your phone with no cloud dependency. Valthor is also extending RangeIQ into an API/SDK for enterprise integrations and iOS platform parity.
Learn about RangeIQ →Android 8.0+ (API 26) required. RangeSight iOS is in development and will be powered by RangeIQ™ for consistent results across platforms.
