Visual graphs & dependencies
See unlocks and holds on a board — not buried in nested subtasks. Held work stays visible until its parents clear.

Syntropy
GTD for people who think in systems — horizons, graphs, and a weekly review that actually fits how you work.
For people who outgrew flat todo lists — and want structure that matches how they already think.
Who it's for
Not another todo list.
If a fast capture inbox and smart lists are enough, stay with what works. Syntropy is for engineers and operators juggling a business, a job, family, and side projects - people who want GTD's horizons, visible dependencies, and a weekly review that feels like a system, not a chore.

Syntropy when you want the system
System model
Horizons of focus, not a flat pile.
Higher levels give meaning to lower ones. A task exists because of a project; a project because of a goal or ongoing responsibility. Syntropy makes that stack explicit — so you always know why something is on your plate.
- AoR
Areas of responsibility
The domains you keep healthy over time.
- Goals
Goals
Finite outcomes that move a domain forward.
- Projects
Projects
Multi-step efforts with a clear done.
- Tasks
Next actions
Concrete work you can engage with now.
Product
Opinionated where it matters.
02
Clarify + Plan Week
Enrich incomplete work before you engage, then run a weekly review that turns capacity into a concrete week plan.
03
Calendar as the engagement surface
Pull Google, Microsoft, or CalDAV alongside timed tasks. Drag work onto the week when you're ready to commit time.
How it works
Classic GTD, made visual.
Five practices. One opinionated workspace. No reinventing the method — just better surfaces for people who already know it.
-
01
Capture
Get it out of your head into the inbox — tags optional.
-
02
Clarify
Decide what it is, what “done” means, and where it belongs.
-
03
Organise
Place it on the horizons stack with projects, goals, and AoRs.
-
04
Review
Plan the week against real capacity and commitments.
-
05
Engage
Work from next actions and the calendar — not a guilt pile.
Early days
Still shaping the problem domain.
Syntropy is actively evolving. If you think in systems, care about GTD structure, and want a more visual workspace than a classic todo app - you are the audience we are building with.
