Single-stream capture
Write every new thought at the top of one stream without choosing a folder, title or tag first.
Minimal notes organized by attention
Gravity is a minimal notes app for iPhone, iPad, Mac and Android. It is built around Andrej Karpathy’s append-and-review method: capture each thought in one stream, periodically review older notes, and bring back only the entries that still deserve attention.
The app is designed for quick capture rather than filing. Notes remain on the device, with optional iCloud sync between iPhone, iPad and Mac. Gravity does not require an account and the homepage describes a one-time purchase model with no subscription; the supplied pricing page does not provide a current price. Android sync is presented as a beta-list option on the site.
Core features
Quick capture
On mobile, type and press Return twice to save. The Mac capture panel opens with Option-Space, and the home-screen widget and share sheet provide additional entry points.
Rescue and resurfacing
Swipe right on iPhone, iPad or Android, or press R on Mac, to move a note back to the top. Each note records when it was written and how many times it has been rescued.
Offline search
Search is performed on the device, works offline and shows results as you type. It can match word beginnings, search inside longer words for terms of three or more letters, and ignore accents.
Note actions and archive
Swipe left to archive, delete, share or copy a note. Archived notes have a separate page and can remain included in search.
Prefix-based filtering
Use prefixes such as todo: or read: to give notes a color and filter matching entries on mobile; Mac users can also narrow search with a tag.
Practical use cases
Everyday brain dumping
Capture short thoughts, reminders and ideas as they occur without deciding where they belong. The stream is suited to people who want one place for work and personal notes rather than separate notebooks.
Tasks and follow-ups
Write an unfinished task, recommendation or reference while moving through the day, then review the stream briefly and rescue only what remains relevant. Prefixes such as todo: and read: can help filter these entries later.
On-the-go capture
Use the iPhone, iPad or Android capture box, widget or share sheet for links and copied text; on Mac, open the capture panel over the app you are currently using. This keeps short inputs out of email drafts or scattered messages.
Research and working notes
Keep a running stream while reading, watching or working. On Mac, Option-Shift-Space adds to the last note, while search can retrieve a name, command or reference later without requiring a folder structure.
Lightweight personal review
Review older entries to notice recurring ideas or unfinished intentions. Notes that do not matter immediately can sink rather than requiring a cleanup session, while search preserves access to older material.

FAQ
How does Gravity's append-and-review method work?
Gravity uses an append-and-review workflow. Add each thought to one stream, review older entries from time to time, and swipe or press a shortcut to rescue anything that still matters back to the top.
How do I capture a note quickly?
On iPhone, iPad and Android, open the app, type in the capture box, and press Return twice, or use the add button. On Mac, Option-Space opens a capture panel over another app; Return twice or Command-Return saves the note.
Can I search old or archived notes?
Yes. Search runs on the device and works offline, with results appearing as you type. It can search archived notes unless that option is switched off, and supports prefix searches such as todo: and read: on supported devices.
Which platforms and sync options are supported?
Gravity is available for iPhone, iPad, Mac and Android. Optional iCloud sync is available between iPhone, iPad and Mac; Android sync is presented as a beta list on the product site.
Does Gravity require an account or subscription?
No. The site describes Gravity as requiring no account and having no subscription. The homepage says notes stay on the device, with optional iCloud sync for Apple devices; the product site does not provide a price in the supplied evidence.
