ChordApp.io - Smart syndicate management for UK flying groups

by•
ChordApp replaces the spreadsheet and SMS chaos most UK aircraft syndicates run on. Purpose-built for shared aircraft ownership, it connects bookings, member ledgers, payment requests, CAA CA-04 compliance, defect reporting, and live weather into one platform. No per-seat fees, a single flat subscription per group. Built by a pilot who served as Trustee, Chairman, and Treasurer across three groups and got tired of chasing spreadsheets. Early access now, iOS app and in-app payments on the way.

Hey Product Hunt! I built ChordApp because I got tired of chasing spreadsheets on Saturday mornings instead of going flying. I've been flying since 2008 and served as Trustee, Chairman, and Treasurer across three UK aircraft syndicates. The admin was tough, chasing outstanding balances, reconciling flight logs with bank statements, filling in CAA forms at short notice. All the stuff that should be automated, wasn't. Existing systems didn't fit, either too big and costly or just online calendars. ChordApp connects everything: book the aircraft and the group gets notified, log the flight and the ledger updates, request a top-up and members get pinged via WhatsApp. No spreadsheets. No group chats to chase. No end-of-month maths. It's in early access now, if you're in a flying group or know someone who is, I'd love your feedback. Happy to answer any questions! ✈️ Robin
