Gravity

Strflow

Gravity

There is no free version or trial, and the iPhone, Mac and Android apps are separate $9.99 purchases.
iCloud sync covers iPhone, iPad and Mac only; the Play listing says it is not available on Android.
There are no folders or tag manager by design, and the developer says he turns those requests down.
The site lists no Windows, Linux or web version, and the Mac app needs macOS 15 or later.

Strflow

The App Store listing covers iPhone, iPad, Mac and Apple Vision only; there is no Windows, Android or web version.
Sync and backup between devices need Strflow Plus; the free plan keeps notes on one device.
End-to-end encryption applies only when the user has turned on iCloud's Advanced Data Protection.
Private tags are limited to Strflow Plus, and the roadmap still lists OCR, voice recording and a calendar view as planned or under consideration.

Gravity

One stream, newest first: All notes sit in a single list with no folders. New notes go on top and older ones sink; swiping right, or pressing R on the Mac, moves a note back to the top.
Markdown and checklists: Headings, bold, italics, lists, links and quotes show formatted, and a line starting with "- [ ]" becomes a checklist that can be ticked from the stream. Notes are saved as plain Markdown text.
Colon tags and offline search: Starting a note with a word and a colon, such as todo: or idea:, gives it a color of its own. Search covers every note, archived ones included, and works offline.
Quick capture: On the Mac, Option-Space opens a capture panel from any app. On phones, a home screen widget and the share sheet create a note at the top of the stream.
On-device storage with optional iCloud sync: Notes are stored on the device with no account and no analytics. iCloud sync between iPhone, iPad and Mac can be turned on; Android backs up to a chosen folder instead.
Export and command-line tool: Notes export as JSON or Markdown. A gravity command-line tool for the Mac lets scripts and AI agents list, search, add, edit and archive notes.

Strflow

Chat-style timeline: Notes are typed into a message box and sent, which builds a chronological timeline. Adding tags creates separate timelines for individual topics.
To-do timeline and reminders: Checklists are collected into a dedicated Todo timeline. A note can be scheduled for a future date; it stays hidden until then and arrives with a notification.
Capture from anywhere: Notes can be added from the share sheet, from widgets, through Apple Shortcuts actions, or on the Mac with a keyboard shortcut that opens a quick note panel.
Rich text and attachments: The editor handles inline and block formatting, checklists, links between notes and link previews. Images and other file types such as PDFs and videos can be attached.
Encrypted iCloud sync: Strflow Plus syncs and backs up notes through iCloud, encrypted with the iCloud Keychain. With Apple's Advanced Data Protection turned on, the data is end-to-end encrypted.
Markdown export and Spotlight search: All notes can be exported as Markdown. Notes, tags, link previews and attachment file names can be found through Spotlight on Mac, iPhone and iPad.
