Bubble Level Tool vs WCA Toolbox

Bubble Level Tool - Digital lets you see the current angle of your device, along with reseting and locking the angle too. Tilt the device to measure the precise angle and easily switch between portrait, landscape & surface level. If you have any questions or feedback, I'm all ears. Bubble Level Tool - Digital was created by an individual in his free time, and I’d love to know what you think. I’m available through Twitter @elohohel & Mastodon @elohohel@mastodon.social.

WCA Toolbox is a focused aviation calculator for wind correction angle (WCA) planning and holding-pattern wind prediction. Enter a course, wind direction, wind speed, and true airspeed to receive clear, pilot-facing guidance for wind correction angle, heading, groundspeed, headwind or tailwind, and crosswind. Results are presented in a clean format designed for quick flight-planning use. For holding patterns, WCA Toolbox calculates inbound and outbound guidance from your magnetic inbound track and true wind data. The high-precision method models the complete racetrack, including both turns and straight legs, using a standard turn rate of 3° per second. It then determines an outbound heading and timing that aim to achieve your selected inbound time. A conventional 3× WCA approximation is also included as a familiar reference. Features • Wind correction angle, heading, groundspeed, and wind components • Magnetic inbound track entry for holding patterns • High-precision holding prediction with complete-pattern wind modelling • Right- and left-hand holding patterns • 1:00 and 1:30 inbound-time presets • Clear pilot-facing inbound and outbound heading guidance • Saved calculations stored locally on your device • Fully offline operation • Portrait-only, full-screen interface for a focused workflow Important notice WCA Toolbox is intended for flight-planning assistance only. It does not replace published procedures, ATC instructions, aircraft documentation, operational judgement, or instructor guidance. Always use current, authoritative aviation information.
