Gobulin
Read full descriptionHide full description
I'm Gobulin, the little goblin who lives in your phone. I'm scared of water — terrified of it — so my nose is sharp: I can smell where it is and which way it's moving. Heading out? Ask me first. "Heh. Nothing around here. Go on." "Hey — hold on, it's just about past." No percentages, no radar maps, none of that. I hate being wet, you hate being wet, we're in this together — so I tell you the one thing you want to hear. Here's what I do: ・The moment you open me, I sniff where you're standing — is it about to come down? ・Tell me where you're going and I'll sniff that whole route ・Water's coming? I'll tell you to sit tight until it's gone ・Come back and tell me if you got wet, and I'll smell it sharper next time Put on a rain poncho and every rider looks like a goblin — you and me, same crew. If I can't smell it, I'll say so instead of bluffing. And if you get soaked, that one's on me.

Know when weather fits your limits. See sun and clouds by hour. Find what to shoot. FlyWindow is a drone weather and planning app for iPhone. Pick a place and drone profile to see the next daylight window that fits the limits you set, with the exact reason behind every result. WEATHER THAT EXPLAINS ITSELF Each daylight hour is checked against your limits for surface wind (10 m), gusts, rain chance and visibility. Instead of a red or green day, you see when conditions fit and what gets in the way: "Gust 11.1 m/s > your 10.7 m/s." Missing data stays missing; it never becomes a passing result. SUN AND CLOUDS, HOUR BY HOUR The Light planner puts the forecast's hourly cloud cover on the sun path, with sun azimuth, elevation, sunrise, sunset, golden hour and blue hour for the selected place and date. Solar timing is computed on your iPhone. Actual light still depends on forecast conditions. FIND PHOTO SUBJECTS WORTH SCOUTING Explore about 465,000 subjects from Wikidata and OpenStreetMap: castles, bridges, towers, viewpoints, beaches and more. Browse a map or list, filter by kind, sort by nearest, prominent or under the radar, and save as many Spots as you like. Photos from Wikimedia Commons show author and licence credits. Free searches around your current location at any radius out to 40 km (25 mi). Pro lets you search around any other place. A Spot is a photo subject, not permission to fly there. Check current local requirements before takeoff. YOUR DRONE. YOUR LIMITS. Choose from 60 verified models across 11 brands or create a custom profile. Starting values are editable size-class suggestions, not manufacturer ratings. PLAN AHEAD WITHOUT LOSING THE DETAILS Free includes every day's verdict, its best daylight window and the reason behind it for all seven days, today and tomorrow hour by hour, the Light planner for today and tomorrow, 2 favourite locations and 1 drone profile. Pro opens the hour-by-hour detail of days 3-7, the seven-day Light planner, 10 favourite locations, up to five drone profiles, and Spots search around any place. HONEST BY DESIGN Forecast by Apple Weather. Kp is estimated by NOAA SWPC and shown only when the feed covers the full day. Wind and gusts are surface values at 10 m. No account. No ads. No tracking. Offline, the last forecast stays visible with its age. FlyWindow checks the weather against your drone's limits. For local requirements, it links to official aviation and drone-rule sources in a searchable directory organized by supported country. FlyWindow does not interpret those rules or grant permission to fly. Check the current source before takeoff. FLYWINDOW PRO FlyWindow Pro is an optional auto-renewing subscription: $7.99 per year or $1.99 per month (USD; prices vary by region).

Verdict
The clearest difference is in-app purchases: Gobulin at none against FlyWindow's 2. FlyWindow's advantage is ads (none vs shown) and iOS requirement (18.0 vs 26.0). On price and device support there is nothing between them.
