What's on your mind? Work, rest, self-care — or skip entirely.

Reflect

Look back across days, weeks, or months whenever you're curious.

04
✨

Notice patterns

Subtle insights surface — only when you want to see them.

Daily check-in

How are you feeling — right now?

One tap, one breath, one honest answer. Sola's check-in takes less than fifteen seconds, so the moment doesn't slip past you.

  • Five expressive moods, no numerical scales
  • Check in as often or as rarely as you like
  • Optional notes, never required

Tagging & context

Give your moods a story.

Was it a long meeting? A walk in the park? A quiet evening at home? Add light context with life-area tags and feeling words — or don't. Sola works either way.

  • Eight life areas: work, rest, self-care, fun, and more
  • Curated feeling words you can tap or extend
  • Add your own — Sola learns your vocabulary
Reflection and insights in Sola
Reflective insights

AI that whispers, never shouts.

Once a month, Sola quietly looks at your check-ins and offers a gentle observation. No diagnoses. No urgency. Just a softer way of seeing yourself.

  • Monthly summaries you can read or ignore
  • Visual mood flow across weeks
  • Always optional, always clearly labeled
Monthly insights — your month at a glance
Letters to your future self

Send a note forward in time.

Write something today — a hope, a worry, a small reminder — and choose when it returns to you. A week, a month, a year from now. The future you will thank the present you for it.

  • Schedule letters for any future date
  • Sealed until the moment they arrive
  • A quiet thread of self across time
Letter arrived — open when you are ready

Sola isn't here to fix you. It's here to help you notice what was already true.

Private by default

Your inner life stays yours.

Sola was built privacy-first, not privacy-as-an-afterthought. Your check-ins stay on your device — we don't offer a cloud backup for them, and we can't read them.

Questions

The honest answers.

Is my data really private?
Yes. Your check-ins stay on your device — we don’t offer a cloud backup service for them. We can’t read your check-ins, and we never will.
Do I have to check in every day?
Not at all. Sola is built to be picked up whenever it’s useful and ignored whenever it isn’t. There are no streaks to break, no penalties for skipping. Some people check in three times a day; others, three times a month.
Is Sola free?
The core app — daily check-ins, tagging, history, and basic insights — is free forever. A small optional subscription unlocks AI reflections, advanced patterns, and unlimited future letters.
How does the AI actually work?
Sola’s reflective insights look at the patterns in your check-ins — moods, contexts, feeling words — and surface gentle observations once a month. It runs on-device whenever possible, and we clearly label any feature that uses cloud AI. You can turn it off entirely.
Is this a replacement for therapy?
No. Sola is a self-reflection tool, not a clinical product. If you’re struggling with your mental health, please reach out to a qualified professional. Sola can sit alongside that work, but it’s not a substitute for it.
Can I export my data?
Anytime. Export everything as JSON or PDF, or delete it all in one tap from Settings.
What devices does Sola work on?
Sola runs natively on iOS 16+. There’s no web version yet — we wanted to ship something deeply native first.
