What you can do with BrightLog

NAME WHAT YOU FEEL

BrightLog gives you a three-level feelings wheel: 7 core emotions, 41 shades, 82 precise words. Proud. Defeated. Hopeful. Overwhelmed. When you can name it, you can work with it. Not sure where to start? A gentle wizard walks you there.

YOUR DAILY MOOD, IN ONE TAP

Open, tap how the day felt — Awesome, Good, Not sure, Bad, Terrible — and get on with your life. Add a note, a photo or a voice memo if you want to. One mood a day, no pressure, no streak-guilt.

A DIARY THAT HOLDS THE WHOLE MOMENT

Write freely, or speak and let your words land in the entry. Attach photos, videos, voice notes and documents. Add a follow-up note later, when your perspective changes — because it does. Search everything instantly. See your month at a glance in the calendar.

A SECRET DIARY, WITH A REAL LOCK

Some days you need to write the thing you would not say out loud. App Lock keeps your journal behind your fingerprint, face unlock or device PIN — the diary with a password you kept at fourteen, except now you cannot lose the key. Your secrets stay on your device.

QUESTION THE THOUGHT (CBT)

BrightLog includes a proper CBT thought record: what happened, what you thought, the facts for, the facts against — and how it looks now. It is the same seven-column model therapists use. Learn to spot the 16 unhelpful thinking styles that quietly run the show.

A POT FOR THE GOOD THINGS

Gratitude deserves its own place, not a checkbox. Save a sentence, a photo or a video to the Gratitude Pot. Once you have ten, BrightLog greets you with one each day — a small ambush of something you had forgotten.

SMALL STEPS, REAL HABITS

Turn what matters into tiny daily actions. Start from nine evidence-based ideas — better sleep, small actions that lift mood, reshaping thoughts, stepping toward what scares you — or build your own. Check in with one tap. Keep a gentle streak, with one forgiving freeze a month.

SIT WITH IT

A meditation timer — 5 to 30 minutes, eleven calm soundtracks (rain, ocean, campfire, forest) or silence, and sixteen on-screen prompts for breath, body scan and grounding. It works offline. No voice, no guru, nobody telling you to breathe deeper.

INSIGHTS THAT ARE ACTUALLY ABOUT YOU

Sign in and BrightLog quietly summarizes your month and your year in your own language: what kept coming up, what changed, and one small thing to try next. Five views — Story, Heatmap, Trend, Wheel and Mood, which lays a whole year of your days out as a grid of color. Export any of it as a PDF.

WALK IN PREPARED

Before your next session, build a six-part summary from any date range and take it as a PDF. Your therapist gets the pattern, not just the worst day. Still looking? The Experts tab finds psychologists, psychotherapists and counselors near you, ranked by distance, never by who paid. Thirty quiet badges mark the milestones — for journaling, gratitude, consistency. No leaderboards, no sharing.

PRIVACY, PLAINLY

Your entries live on your device. There is no BrightLog server that receives them — we never see what you write. Backups go to your own Google Drive, not to us. AI insights are optional and only ever send the text you ask BrightLog to analyze — never your photos, voice notes or files.

Your diary stays on your phone

BrightLog is built so we can't read what you write — not as a promise, but as the way it works.

  • We never see what you writeYour entries are saved on your device. There's no BrightLog account holding your words, and no BrightLog server that receives them.
  • Backups go to your cloud, not oursBack up to your own iCloud or Google Drive with one tap. It's your folder — we can't open it.
  • Lock it with your face or fingerprintApp Lock adds Face ID, Touch ID, fingerprint or your device passcode on top of everything else.
  • The AI only ever sees what you hand itMonthly and yearly insights are optional. Only the text you ask us to analyze is sent — never your photos, voice notes, documents or files.
  • Anonymous usage statistics onlyWe count things like how often a screen is opened, so we know what to improve. We never collect what you write.

Frequently asked questions

Does BrightLog read my diary?

No. Your entries are stored on your device, not on a BrightLog server, and we never see what you write. The only text that ever leaves your phone is the text you explicitly ask the AI to analyze for a monthly or yearly insight — never your photos, voice notes, documents or files.

Is BrightLog really free?

Yes. BrightLog is free on the App Store and Google Play, with no in-app purchases, no subscription and no paid tier. Every feature described on this page is included.

Does BrightLog work offline?

Yes. Your diary, mood check-in, the Gratitude Pot, goals, thought records, the meditation timer and the Feelings Wheel all work with no connection at all. Only the optional AI insight needs the internet and a sign-in.

Do I need an account?

Not to write. Install BrightLog and start journaling right away. A sign-in is only needed for the optional AI insights and for cloud backup to your own Drive.

What is the feelings wheel?

Most apps give you five faces. BrightLog gives you a three-level wheel — 7 core emotions, 41 shades, 82 precise words — so you can move from “bad” to the word that actually fits: defeated, anxious, overwhelmed, hopeful. A gentle wizard walks you there if you're not sure.

Can I back up my diary and move it to a new phone?

Yes. Back up to iCloud on iPhone or Google Drive on Android with a single tap, and a monthly automatic backup keeps it current. Restore everything on a new device whenever you need to.

Does BrightLog collect any data about me?

Only anonymous usage statistics — for example how often a screen is opened — so we can see what to improve. Never the content of your entries, your photos or your voice notes. You can read exactly what is collected in the privacy policy.

Can I share what I've written with my therapist?

Yes. BrightLog can build a report over any date range — mood and emotion trends, triggers, thought patterns, what shifted and points to discuss — and you can share it as a PDF or copy it out. It's generated only when you ask for it.

Can I delete everything?

Yes, at any time, from inside the app — your entries, your media and your backups. Nothing is kept behind. The account-deletion page walks through every step.
