About Asympta Writing
Asympta Writing is a quiet, infinite canvas for handwritten notes, sketches, 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 paper with moving leaf shadows, an open sky with drifting clouds, or a night sky with stars • Listen to wind, sea ambience, or summer-night insects and frogs 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.
What’s new
Version 1.1.2 · Updated October 10, 2026
More comfortable writing, with a quieter Night Sky. • Fixed accidental long lines caused by palm touches on iPad. Using Apple Pencil now switches finger writing off and remembers the setting, including after pauses and reopening the app. • Long-press the drawing tool to turn finger writing back on. Two-finger pan and pinch-to-zoom remain available. • Finger writing now has a blue or gray dot beside On or Off, with larger, clearer status text. • Softened the continuous Night Sky insect ambience so frog calls and quieter details are easier to hear. • Night Sky background playback now glows with a gentle yellow dot, like a firefly, when enabled.
