Your diary, goals, health and accountability, in one private app.
Write in your own words and get one good question back. Plan for what gets in the way, see your health data alongside your days, and share your progress with your therapist if you choose. Built on published research on goal setting and reflective writing.
Write it your way, and get one good question back.
Entries in your own words, typed or dictated. The AI replies with one open question.
Work toward what matters, and plan for what gets in the way.
Choose a focus (health, mindfulness, sleep, habits or studies), name the obstacle, make one if–then plan, check in, then keep it or set it aside. You commit every goal; the AI never sets, ranks or commits one.
See your health data alongside your days.
From Apple Health or Health Connect: sleep, steps, active energy, workouts, mindful minutes, resting heart rate and heart rate variability. Each source only with your permission, and you can disconnect it.
Share your progress with your therapist, if you choose.
Link to a therapist or counsellor on MendAI Companion with a code they give you. Choose what is shared in Diary's permissions, and stop at any time.
One question at a time.
Choose the AI's tone at sign-up and change it any time. Give it a name if you like — Sage, Wren, Echo, Pip, Ada, or your own.
Nothing you write is sent to the AI model before the app tells you who receives it and asks.
Reflect
Turns a thought over and looks at it from another side.
Unpack
Notices what was passed over quickly, and gently asks about it.
Action
Reads the entry against your goal and suggests one small step for today.
Write, plan, see your health, and share if you choose.

Check-ins
Your own account of how a goal is going. Nothing is computed from them.
Set aside
A goal can be set aside without being marked as failed. Its history is kept.
Bloom
A picture of your recent weeks on the home screen. Never progress, a score or a streak; never ranked, compared or shared. No streaks, scores, levels, badges or percentages anywhere in Diary.
Share what you choose. Stop at any time.
Diary is complete on its own. If your therapist or counsellor uses MendAI Companion, you can link to them with a code they give you and choose what is shared, one category at a time. You can stop at any time.
