What’s new

Everything we’ve added to Satura, newest first. The core stays free, private and offline - always.

More reliable colour-vision tests

v0.7.1
  • Both colour-vision tests now show their colours on a fixed neutral background, so a dark theme can't tint what you see and skew the result.
  • Clearer wording about how sign-in works (a 6-digit email code, no password).

New guides, a What's-new page, and a steadier offline app

v0.7.0
  • New practical guides: living with red-green colour blindness, protanopia vs deuteranopia, and how reliable online colour-blind tests really are.
  • This page - see what's changed in each release, in plain language.
  • Behind the scenes: the whole app is even more dependable offline after you install it.

Sync your library across devices, plus an advanced vision test (Pro)

v0.6.0
  • Pro: turn on cloud sync to keep your saved-colour library in step across every device you sign in on. It's off by default and your library always stays on your device too.
  • Pro: a new advanced colour-vision screening that arranges colours to suggest which confusion axis your results lean toward - with optional per-eye testing.
  • Your test results are now saved on your device so you can look back at them.

Back up and restore your whole library - free

v0.5.0
  • Export your entire saved-colour library to a single file, and restore it on another device or a fresh install. Free for everyone, nothing uploaded.
  • Restoring merges sensibly with what you already have and tells you exactly what it imported.

Simpler, more reliable sign-in

v0.4.0
  • Sign in with a 6-digit code emailed to you, instead of a magic link - which now works properly in the installed app on iPhone and iPad.
  • Added an optional way to support Satura with a one-off tip (it unlocks nothing - the core stays free).

Pro unlock, and shareable result cards

v0.3.0
  • Unlock Pro with a single £10 payment - no subscription - for an unlimited library, exports and full palettes.
  • Share your colour-vision result or a palette as a tidy image card straight from the app.

A correction filter, everyday tools, and a saved library

v0.2.0
  • A new filter recolours photos and your live camera so confusable colours separate out - not just simulation, but help.
  • Quick tools: match-or-clash, a contrast checker, an eyedropper, palette-from-photo, and a side-by-side 'show a friend what I see'.
  • Save colours with your own names and notes, then search, edit and export them - all on your device.

Satura launches

v0.1.0
  • Identify any colour from your camera, a photo, or a value you type - with the name read aloud if you like.
  • Simulate protanopia, deuteranopia and tritanopia, and take a quick private colour-vision screening.
  • Free, private, and works offline once installed - no account needed.
