What it does
Skyty turns your iPhone into an offline flight instrument. See your real altitude above ground, ground speed, heading, nearest airport, and ETA — all calculated on-device using NASA terrain data. No internet, no flight number, no tracking. Just GPS.
Skyty shows your real-time position, altitude, speed and map during flight — completely offline. No WiFi, no data, no subscriptions.
Position, altitude, speed and a world map — without WiFi, without data, without subscriptions. Built for travelers at 10,000 m. Skyty bundles a full vector world map and an offline GPS pipeline into a single iOS app — no servers, no API keys, no surprises in airplane mode. GPU-rendered vector tiles via Protomaps + MapLibre. Four themes: Aviation Dark, Aviation Light, Satellite, Topographic. Coordinates, altitude, speed, course and accuracy — refreshed live, never leaves the device. NASA SRTM terrain data computes AGL — switch between MSL and WGS84 ellipsoidal in one tap. Auto-detect take-off and landing, draw the route, plot the altitude profile, export GPX.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
