Apple Intelligence · On-device

An AI that understands your day.

The heart of Todai: planning that knows your energy profile, respects your calendar — and never leaves your iPhone.

Heart of the app

Planning that actually fits you.

Fully on-device: AI planning runs with FoundationModels directly on your device — no server is contacted to analyze your tasks. For syncing between your Apple devices, you use your private iCloud.
Psychological daily profile: warm-up → deep work → medium tasks → light things in the evening. Never two demanding tasks back to back.
Automatic assessment: energy level and realistic duration are recognized as you type — and learn from your real times.
Calendar awareness: existing events are sacred — no plan block ever overlaps them.

Psychological daily profile

Never two demanding tasks right after each other — energy follows a proven curve.

The day starts with light tasks that gently get you going.

Highly cognitive tasks land in your energy peak — where you're strongest.

After the concentration peak come tasks of medium demand.

The evening belongs to easy tasks — with breaks in the right places.

Even more intelligence

As you type, the AI realistically estimates how long a task will take — and learns from your real measured times.

Tasks with a fixed appointment are set as anchors — everything else is planned automatically around them.

Not just today: plan any future day and head into the week with ease.

Completed tasks stay untouched, only open ones get re-planned — the old plan safely lands in the archive.

The AI splits big tasks into sensible sessions — with count and minutes per unit.

If Apple Intelligence isn't available, a deterministic algorithm takes over using the same principles.
