Capture your life.
One thought at a time.
For centuries, the world's greatest minds kept journals. Now, you can preserve your journey in just 15 seconds a day—by simply speaking.
Free download. No commitment. Your memories stay private.
The ancient practice that changed history.
Marcus Aurelius wrote his Meditations in a journal. Leonardo da Vinci sketched his ideas. Benjamin Franklin tracked his daily virtues. Your story matters just as much.
See how far you've come
Looking back at where you were a year ago reveals growth you never noticed day-to-day. Your struggles, victories, and quiet moments—all preserved.
Leave something behind
Your children, grandchildren, and loved ones will treasure these glimpses into your life. What you thought, felt, and experienced—in your own words.
Understand yourself deeply
Patterns emerge when you record your days. You'll discover what truly makes you happy, what drains you, and who you're becoming.
Journaling, without the friction.
The barrier isn't desire—it's effort. We've removed it.
Just speak. We'll write it.
No typing. No blank pages. Just hold the button for 15 seconds and speak your thought. AI transcribes it beautifully, removing "ums" and capturing what matters.
Time-travel through your life
Every morning, see what you wrote on this exact date in previous years. Watch yourself evolve. Rediscover forgotten joys. Remember how you survived hard times.
Your personal historian
Ask your journal anything. "When was I last this happy?" "What worried me in 2023?" AI analyzes your entries and reveals insights you'd never find on your own.
Your story, your vault
These are your private thoughts. Everything stays on your device. Optional encrypted iCloud backup. Face ID protection. No company reading your entries. Ever.
Pass it down
Export your complete journal anytime. Share it with family, print it as a book, or archive it for the future. Your legacy, in any format.
One entry. One moment.
Not a novel. Just one thought about today. The constraint makes it sustainable. You'll actually keep going—and that's what builds a life story.
15 seconds. That's your entire commitment.
If you can send a voice message, you can build a lifetime archive.
Open the app
No login screen. No blank page staring at you. Just one button, waiting for your voice.
Hold & speak naturally
"Today I realized..." or "I'm grateful for..." or just "Tough day, but I survived." Say whatever comes to mind. Release when you're done.
Your story is saved
AI transcribes your words, removes the "ums," and archives this moment forever. Done. Tomorrow, you'll capture another thought.
Your words. Your device. Your control.
We believe your thoughts should stay private. That's why One Thought Journal stores everything locally on your device. No servers storing your entries. No algorithms reading your journal. No accounts to create or manage.

Will I actually stick with this?
That's what makes this different. You've failed at journaling before because it required too much effort. This takes 15 seconds of speaking. If you can text, you can do this. The one-entry limit removes decision paralysis. Most people who start are still going months later.
Is my data really private?
Completely. Your journal entries never leave your device unless you choose encrypted iCloud backup. No company servers. No one reading your thoughts. Face ID protection. You can export and delete everything anytime. Your story belongs to you alone.
What if I miss a day?
Life happens. You can go back and fill in missed days anytime, or just skip them. This isn't about perfection—it's about capturing what you can. Even 200 entries over a year gives you 200 moments you'd otherwise have forgotten.
Can I share my journal with family and friends?
Absolutely. Export your entire journal or specific date ranges and share however you like—email it, print it as a book, or save it to share with your children someday. Many users create annual exports as keepsakes for their families.
What if I don't know what to say?
Start simple: "Today was hard" or "Had coffee with mom" or "Feeling grateful." Over time, you'll find your rhythm. The constraint of one thought makes it easier, not harder. You're not writing a novel—just capturing a moment.
How much does it cost?
The app is completely free. All features are included at no cost—AI transcription, search, insights, export, everything. No subscriptions. No in-app purchases. No hidden costs. We believe preserving your story shouldn't cost money.
