A little thought.
A whole universe.
Some thoughts arrive quietly.
Give them a place to stay.
enough to begin.
Less organising.
More being.
An idea on a walk. A sentence you don’t want to lose. Something to remember when the time is right. Spark starts with a single thought.
What if the best ideas
need a little room?
Open a book before
opening another tab.
Take a walk
after lunch tomorrow.
Sample thoughts, for illustration.
Your thoughts.
Your little corner.
Your library is kept on your iPhone. No public feed. No advertising. No account to create. Voice can use cloud transcription, and subscriptions use Apple and RevenueCat—we explain that in plain language.
Read the Privacy PolicyA few things to know.
When can I download Spark?
Spark is being prepared for release on the iPhone. It is not yet publicly available on the App Store. This website introduces the app as it is being built.
What can I do with a thought?
Write it or dictate it. Keep it in your personal space, find it with local text search, edit it, share it, or archive it. Spark can bring thoughts back through reminders and resurfacing notifications, with your permission.
Does everything stay on my iPhone?
Your thought library is stored on your iPhone. Voice transcription prefers on-device processing, but audio can be sent to OpenAI when local transcription is unavailable. Apple and RevenueCat process subscription information. The Privacy Policy explains these boundaries.
Does Spark sync my thoughts across devices?
Spark does not currently provide its own cloud backup or cross-device sync for your thought library. Your iPhone’s backup settings may include local app data. Keep copies of important thoughts before changing devices or removing the app.
What is Spark Pro?
Spark Pro is an optional subscription that supports Spark’s continued development. Existing thought tools remain available. The app shows the plans, local prices, and any trial you are eligible for before you confirm a purchase with Apple.
