Coming to iOS · Q4 2026

Kairō, on your wrist and in your pocket

The web demo proves the concept. The iPhone app makes it a habit. Voice capture lives where your voice already does — not at a desk.

Why mobile is where Kairō lives

A 5-minute daily habit fails on a laptop. Phones are with you when the thought happens — walking home, between classes, after the meeting that mattered.

Voice-first capture

Hold-to-talk on the lock screen. Whisper transcribes on-device. The thought leaves your head and enters Kairō without you breaking stride.

Day-3 push recall

At 7 PM on day three, a notification surfaces something you said on day one. The wow moment lands before churn typically would.

On-device processing

Voice never leaves your phone. Whisper runs locally on Apple Neural Engine. ChromaDB stores vectors in the app sandbox. Privacy is the architecture.

Wireframes & design rationale

Six core screens, annotated. Each one has a single primary purpose, a deliberate reading order, and design decisions documented for engineers and judges alike.

Screen 01

Home — your second memory at a glance

The first thing the user sees every day. Streak status, day-3 recall card, and quick stats. The recall card is the single most important UI element on this screen — it is where retention happens.

Reading order
Greeting → streak → recall → stats → primary action.
Primary CTA
"Today's check-in" button anchors the bottom of the scroll. Always reachable by thumb.
Hierarchy decision
Streak comes before recall because loss-aversion drives the open. Recall is what makes them stay.

Voice journal — friction-free capture

Single-purpose screen. One large microphone button is the entire UI. Live transcript appears as user speaks. Auto-detected domain tags surface after recording stops.

Constraint
No text fields, no menus. Speaking is the only input. Stop is the only action.
Feedback loop
Pulse animation while recording. Live transcript proves Whisper is working in real time.
Post-capture
Domain tags appear after stop — confirming the system understood, before the user navigates away.

Ask memory — RAG with receipts

The differentiator screen. Chat-style interface for natural language queries. Every answer cites the specific past memories that informed it. This is what separates Kairō from generic chatbots.

Trust mechanic
Source cards under every answer make the AI auditable. User can tap any source to see the original memory.
Input position
Input bar floats above the tab bar — ergonomic for one-handed use, follows iOS conventions.
Empty state
When user has nothing yet, suggested questions seed the experience. Becomes the second-day onboarding.

Timeline — every memory, browsable

Chronological feed of every check-in. Filter pills at top let users drill into a single domain (career, health, etc). Cards show domain tags, timestamp, and snippet preview.

Default view
"All" filter active by default. Most recent at top. Infinite scroll.
Tap target
Whole card is tappable — opens full memory detail with playback option.
Visual rhythm
Cards are uniform width but variable height to handle short and long entries gracefully.

Weekly digest — patterns the user missed

Auto-generated every Sunday. Three categories: patterns detected (e.g. sleep correlation), open questions (deflections, unresolved threads), decisions made. Sent as push notification.

Cadence
Weekly — frequent enough to feel alive, rare enough to feel curated.
AI voice
Written in second person ("you"). Reflective tone. Never prescriptive — surfaces patterns, does not tell user what to do.
Stats footer
Three numbers reinforce habit formation: check-ins, memories captured, domains touched.

Domain insights — where your mind goes

Visualizes how the user's memory distributes across life domains. Horizontal bar chart with counts per domain over the last 30 days. Helps users notice imbalance.

Insight, not judgment
No "you should journal more about X" prompts. The visualization itself is the insight.
Time range
Default 30 days. Tappable to switch to 7-day, 90-day, all-time.
Animation
Bars grow from 0 on screen open — small detail that makes the data feel alive.
