Show HN: Tigement – private timeline planner that recalculates when tasks change

sodomak Wednesday, February 11, 2026

I got tired of rewriting my day plan when one task runs long — so I built a planner that auto-recalculates

I originally coded mostly personal slow&buggy:) version of this workflow ~6 years ago and have used it daily since. Recently I rewrote it properly and made it public as Tigement.

Idea:

You plan your day as a timeline of tasks with durations. When one task changes (overrun / pause / skip / reorder), everything after it recalculates instantly so the plan stays consistent.

Notes that might interest you:

- It’s a web app and you can try the core workflow without signing up (local-first; stored in the browser).

- Free mode is local-only + export/backup.

- Premium adds multi-device sync where the server stores ciphertext only (end-to-end encrypted), plus E2EE table sharing (view/edit) for collaborating on schedules/tasks.

I’d love feedback on:

- is there anything what’s unclear in the first 30 seconds?

- the UI: any glitches (it's still beta:) )?

- basically anything - I am pretty bad with launch process:)
