## What is Asympta Writing?

Asympta is a calm space for handwriting, words, and ideas, with natural sound and gently changing light.

• Write and draw with Apple Pencil, or add typed text with an adjustable size preview
• Organize your writing into separate Spaces and return to earlier thoughts on a spatial canvas
• Choose a paper scene with moving leaf shadows or an open sky with drifting clouds
• Listen to wind or sea ambience with an independent volume control
• Enable background playback in the sound controls to keep ambience playing on the Home Screen and while your device is locked
• Use the eraser, move and focus tools, and export your canvas as a PNG image

The free plan includes every canvas tool, local storage, up to three Spaces, and iCloud sync when your device has an available iCloud account. You can use the canvas offline without an Asympta account.

One non-consumable lifetime purchase unlocks Asympta Pro: unlimited Spaces, optional Google Drive backup, merge and recovery between your existing iCloud and Google Drive accounts, and two one-time discounted App Store invitation slots. iCloud sync itself remains free. The purchase does not include additional iCloud or Google Drive storage.

Google Drive connection is optional and uses only the app data scope. Invitation links open Apple's App Store redemption flow, where Apple displays the local price.

Asympta contains no ads, third-party analytics, or cross-app tracking.
