Fully offline, truly private
Every word, every exercise, every session runs entirely on-device. Zero network calls, zero third-party code — your data never leaves your phone. Reliable in hospitals, care homes, and anywhere connectivity is limited.
🌍
16 languages, one app
English, Spanish, Hindi, Gujarati, Chinese, Farsi, Korean, Vietnamese, Arabic, Portuguese, Tagalog, Punjabi, Armenian, Japanese, French, and Amharic — each adapted for its community, with native speaker review in progress. Switch languages in one tap from the Profile tab. Full right-to-left support for Farsi and Arabic.
🎯
30+ exercises per language
Covering language skills, cognition, and functional daily living. Sessions are short, varied, and gently adaptive so fatigue never becomes a wall.
🎚️
Adapts as you improve
Clarity quietly adjusts difficulty across all 16 languages — no settings to fuss with, no numbers to track. A short Baseline Assessment on first run sets the right starting point automatically. Progress insights adapt to the goal: recovery-oriented for stroke and TBI, stability-oriented for progressive conditions like Alzheimer's and FTD.
🛡️
Built for caregivers too
A PIN-protected Caregiver Mode gives family members and clinicians access to manual difficulty controls, therapy notes, goal setting, and a full exportable PDF progress report. Local notifications keep patients on track: a daily practice reminder, a streak-at-risk nudge if they haven't practised by evening, and a welcome-back message after a few days away.
⚡
5 questions per session
Brief by design. Five thoughtfully chosen questions per session respect the energy levels of recovering patients, while building a consistent daily habit without overwhelm.
🏆
Progress you can see
Streaks, badges, and a calendar view make practice feel rewarding. Seven achievement milestones mark real progress, from first session to 30-day streak.
🎲
Surprise Me
One tap on the Surprise Me button launches a random activity. Perfect for caregivers looking for a quick, low-friction session with a loved one.
📱
Today's practice on your Home Screen
The Clarity widget shows your current streak, today's recommended exercise, and your weekly goal right on your iPhone Home Screen. One tap launches straight into the activity — no hunting through the app.
📺
Play together on Apple TV
Two-player mode lets two people take turns on the same Apple TV using one remote — a natural fit for a caregiver and patient practicing side by side. All 16 languages, all exercise types, no extra setup.
🧭
Recovery or Maintenance framing
Caregivers choose whether progress is read as recovery (stroke, TBI) or maintenance (progressive conditions), and can mark that day-to-day ups and downs are expected. Insights follow that choice.
📊
Caregiver insights
