Flyby is a preflight companion for drone pilots who want a clearer answer before takeoff: is this a good time and place to fly?

Open Flyby to see a flight-ready snapshot for your current location or a saved launch spot. Fly Score brings practical signals together in one place, so you can decide faster and with more confidence. It factors in wind and gusts, visibility, rain and cloud cover, daylight and timing, magnetic conditions, estimated flight time, and your personal comfort limits.

Built for real launch decisions, not generic weather browsing.

Flyby helps you:
- Get a simple Fly Score before you unpack
- Compare current conditions across multiple saved launch locations
- Review hourly updates for wind, gusts, rain, clouds, and visibility, with a score that reflects what matters to you
- Plan around sunrise, sunset, golden hour, blue hour, and available daylight
- Tune warnings and limits to match your aircraft and how you fly
- Estimate usable flight time with battery reserve and accessory load included
- Preview launch areas on a map with airspace context where available
- Track your local flight history with a built-in log
- Import GPX tracks from past flights to keep details like launch point, route distance, altitude, duration, and notes up to date
- Find scenic nearby candidates with Flyby Guide

Designed around pilot questions
Are gusts getting worse? Is visibility good enough for your target? Is the light worth waiting for? Will this battery plan still leave a safe reserve? Does another saved location look better right now?

Your setup matters
Choose a drone preset or create a custom aircraft profile. Flyby uses your aircraft and pilot limits to shape warnings, score factors, and estimated flight time so the app reflects your real-world constraints.

Maps, charts, and tables that are easy to use
Use the Today view for the quick answer, then go deeper when needed. Charts show hourly trends. Tables make key signals simple to scan. Sun tools help you plan by daylight timing. Maps display saved locations, condition previews, Flyby Guide candidates, and supported airspace overlays.

Privacy-first by design
Flyby follows the O13 Standard: local by default, no trackers, no banner ads, and no unnecessary data collection. The goal is better launch decisions, not turning your flying habits into a data product.

Important: Flyby is for planning and weather context, not authorization. Always verify local rules, temporary restrictions, LAANC requirements, manufacturer guidance, aircraft condition, people, wildlife, and launch access before flying.

Weather Nerd: Advanced, glanceable weather - anywhere on earth. Skiers chasing snow, sailors and kiters timing a wind window, hikers watching a front. Real model data and charts you can read at a glance on iPhone, iPad, and Mac.

PICK YOUR MODEL
Most apps blend everything into one forecast and don't tell you how. Pro lets you pick the model behind each location: ECMWF, ICON, GFS, HRRR, NBM, and Canada's GEM family down to 1 km resolution. Short-range models hand off to a longer-range one so the full 10 days are covered. Apple Weather is the free default.

COMPARE THEM ALL
Overlay every model's temperature, precip, and wind. The spread shows you how confident to be.

THE REST
- Dark instrument-style design with monospace numerals
- 10-day forecast with Temp, Precip, Snow, and Wind modes
- Radar
- Multiple locations with iCloud sync, and forecasts stay readable offline
- Widgets from a quick temperature glance to large Wind and 10-Day boards
- Share images of current conditions, any day, or the full outlook
- El Niño tracker

Built for weather nerds. Simple enough for everyone else.
