Mood Spectrum
A word, not a score.
See whether you've been lower or higher than your usual, in plain language. Nothing is “good” or “bad”, and nothing is red.
Coming soon to iPhone
Notice when your days drift from your usual.
Evenline is a calm, private place to check in on your mood, energy and sleep in about thirty seconds — and to see, gently and over time, when things start to shift from your own rhythm.
- Encrypted on your iPhone
- No ads, no tracking
- No streaks
A thirty-second check-in
Tap a few things. Close the app. Get on with your day.
No essays, no scores to chase. Evenline asks a handful of gentle questions and does the noticing for you.
How's your mood?
Mood and energy are asked separately, because they don't always move together.
How did you sleep?
How it felt to you — plus measured sleep if you connect a source.
Anything stand out?
Optional. Note what you noticed — or simply say “none noticed”.
Your rhythm, not an average
Everyone's normal is different. Evenline learns yours.
After about thirty nights it knows your usual. After ninety, it's steadier. Until then, it says it's still learning instead of guessing.
Timeline
See what moved together.
Sleep, mood, energy and life events on one calm timeline, with every note labeled by where it came from.
These changes happened around the same time. They don't show what caused what.
Sleep
Reads your sleep. Never writes.
Connect Apple Health or an Oura ring, or just tell Evenline how you slept.
Companion · optional
Bring in someone you trust.
Share only what you choose with a partner or family member. They can add what they notice; you review it first.
Your plan
Your own words, ready when you need them.
Write down your early signs and what helps while you're feeling well. Evenline shows it back; it never adds advice.
Made to be gentle
Honest about what it knows — and what it doesn't.
No streaks, ever
Missed a day? That's fine. Nothing resets and nothing nags.
Missing isn't “fine”
If there's too little to go on, Evenline says so instead of filling the gap.
Together ≠ caused
When things change around the same time, that's all it claims.
Not a diagnosis
Evenline notices changes. It doesn't label you, and it isn't medical care.
Private by design
Your journal stays on your iPhone.
Check-ins, notes and your plan are encrypted on your device. You don't need an account. Nothing leaves unless you choose to share it.
