Hey Strivle, I'm glad to be a part of this community. I built and shipped Line Cal. You can sync your existing calendars from other apps to turn them into a linear timeline by signing in, or you can just use it immediately without signing in. It integrates notes and a Kanban task board seamlessly, is mobile-optimized (with PWA support & native apps coming relatively soon), and localized across 21 languages (with more coming). If you'd appreciate a calendar UI that resembles a Gantt chart, with rich calendar-specific features, Line Cal is worth checking out.
