.haesol app icon

One thing, at a time. Nothing else competing for it.

.haesol is a subtraction tool, not a productivity app. At any moment it shows you exactly one thing that matters right now — everything else is absent, not just hidden.

Coming to iPhone & iPad How your data works
Why

Choice is the tax. Not too little willpower — too much visible at once.

The modern digital environment taxes executive function for everyone, not just ADHD brains: choice paralysis, over-scheduling, an infinite to-do list you can always scroll further into. .haesol is a structural guardrail against that, not another dashboard competing for your attention.

The daily loop

An evening offload. A morning that starts on one thing.

Sunset Review

A quick glance at tomorrow, three focuses set the night before, then a hard lock — no re-litigating the plan until morning.

Bright Eye

Wakes up to one visible task, not a list. The next one stays hidden until the current one is done.

Built different

Your data has one home: your device.

Not a privacy feature bolted on afterward — the whole architecture is built around it.

Nothing leaves your device. No cloud database, no account, no login.
$0.00 to run, forever. That's a promise the architecture depends on, not a pricing decision that can quietly change.
No tracking, no ads. Calendar access is read-only through iOS permissions — never transmitted anywhere.
Any on-device AI stays on-device. No external API calls, ever — see the full breakdown on the Privacy page.
