About

Useless Notes

Features
Read full description

Useless Notes is a creative note-taking app that lets you capture ideas in an infinite, freeform canvas environment. Instead of traditional lists, you can add text notes, links with previews as colorful cards that can be positioned and scattered anywhere on the canvas. The app embraces a playful, casual approach to organizing thoughts—cards appear at random positions and angles, giving your notes a natural, organic feel. You can delete notes with a fun burning animation, filter by different types of content, and search through your notes when you need to find something specific. It's perfect for anyone who wants a more visual and less structured way to capture thoughts, ideas, and inspiration without the constraints of traditional note-taking apps.

About

SurfaceOps by uAvionix

Features
Read full description

Surface Ops is a free situational-awareness tool for anyone interested in airport surface operations — pilots, students, ramp staff, plane spotters, and the general public — with optional licensed features for professional airport ground-operations teams. Free for everyone, at every US airport: • Airport diagrams (runways, taxiways, aprons, hotspots) • GPS-based ownship position on the airport surface • METAR, TAF, and D-ATIS weather • Live ADS-B traffic from a uAvionix skyAlert receiver (a separately-purchased consumer accessory) • Runway-incursion alerts: CHECK RUNWAY, TRAFFIC RUNWAY, CHECK FINAL, TRAFFIC FINAL and Aircraft Emergency Alerts • Visual highlighting of the runway under alert • Offline operation once an airport diagram is cached (weather requires internet) Optional licensed feature, at participating airports: Airports that contract with uAvionix for the professional toolset can issue a one-time activation code to their authorized vehicle operators, which adds the FlightLine ADS-B network traffic feed from the airport's ground-based receivers, no per-vehicle hardware required. No in-app purchase. The app and all consumer-facing features are free. Licensed airports pay uAvionix directly; the end-user operator never pays anything inside the app. What Surface Ops is NOT: • Not a certified safety system • Not a substitute for ATC instructions or established ground-movement procedures • Not a primary means of collision avoidance — visual scanning and radio communication remain primary Privacy Surface Ops collects only what's needed to operate: your activation code, a per-device licensing identifier, and—with your permission—your GPS location to display your position on the airport map. Location data stays on the device; we do not transmit it to our servers. No analytics, no advertising SDKs, no tracking.
