01
Health-first language
Kairos avoids euphemistic design. It treats sexual health with the same precision and dignity expected in any clinical wellness app.
Sexual Health Tracking for iPhone
A modern health app for your most personal rhythms.
Whether you're tracking solo, with a partner, or both — Kairos gives you a private, clinical-grade picture of your sexual health. No euphemisms, no cloud you can't trust, no data that leaves your device.
- Solo & partnered tracking
- Automatic encrypted sync
- On-device intelligence
Named for Kairos
The Greek concept of the right moment.
02
Warm, not sterile
Amber and lavender tones, layered materials, and gentle motion create emotional safety without sacrificing clarity.
03
Quality over quantity
The experience is built around meaning and timing, helping users understand when and why shifts happen across their personal patterns.
Core experience
Simple daily interactions, deep long-term insight.
Today Dashboard
Your home base in Kairos. See your current desire level, recent check-ins, and activity at a glance. The sparkline shows your 7-day desire trend, and one-tap logging gets you in and out in seconds.
- Daily desire check-in with visual trend
- Quick-log button for fast entries
- Recent activity feed with mood context
- Status messages that adapt to your patterns
Configurable Logging
Every entry starts with a context — solo or partnered — and adapts from there. Two logging modes let you control depth: Personal mode captures the essentials, while All mode opens every field from mood and energy to protection, location, and clinical notes.
- Solo entries with full standalone detail
- Partnered entries with connection context
- Per-context defaults that remember your preference
- Mood, energy, and desire tracked before and after
Dual-Lane Timeline
Solo and partnered entries each get their own lane in a single chronological timeline. Whether you only log solo activity or track both sides, the separation keeps patterns readable and honest. Filter, scroll by month, and tap any entry for full detail.
- Filter by All, Solo, or Together
- Rich entry cards with tags and mood context
- Monthly grouping with smooth scroll navigation
- Duration, protection, energy, and location at a glance
Intelligence layer
Patterns you can feel. Data you can trust.
Kairos turns raw entries into narrative summaries, frequency charts, desire curves, and mood correlations. Everything computed on-device.
Your Story
A natural-language summary of your recent activity. Kairos distills weeks of data into clear sentences: how often, what type, your average desire, and how your mood shifted after entries. No dashboards to decode.
25 Entries
5.8 Per week
+2.2 Mood shift
Activity Patterns
Entry frequency over time, broken down by solo and partnered activity. See which days and weeks you're most active.
Desire Trends
Averaged desire readings plotted over time, with peak and daily pattern curves.
Desire by Day & Time
Which days and times your desire peaks. Discover rhythms you didn't know you had.
How You Feel
Mood before vs. after, energy levels, and emotional trends correlated with desire.
Optional partner sharing
Shared context, separate control.
Kairos works as a complete solo tracker on its own. If you're in a relationship, you can optionally connect with a partner to share desire levels, mutual entries, and connection context — without exposing your solo entries or private data.
Invite & Connect
Send a magic link to your partner. Once accepted, shared data flows automatically through encrypted iCloud — your solo entries stay completely private.
Shared Dashboard
See your partner's desire level, shared activity history, and connection status at a glance. Each person controls exactly what's visible.
You're always in control
If you disconnect, you choose what happens to shared data. You can remove your entries from your partner's device entirely, or let them keep a copy. Either way, the connection ends cleanly — no residual access, no lingering sync.
Privacy is product
Your data, your device, your private iCloud database.
Kairos syncs automatically to your private CloudKit database — encrypted in transit and at rest, stored in a container only your devices can read. Not even Apple can access it. No opt-in, no toggle. This is how it works by default, following Apple's best practices for sensitive health data.
- Automatic encrypted iCloud sync to your private database
- No third-party analytics SDKs — zero external data collection
- Point-of-need permission requests only
- Clinical export support for care conversations
- No advertising, no data brokering, ever
