I made an Android phone watercolour app called Waterwheel. This post is the pinned intro if you're new here, because Tumblr is like the only place online that keeps getting rediscovered by confused people in pith helmets.
Iiiiiif you've landed on this blog and you're wondering what I'm up to lately: I built an Android app for watercolour painters, and this is the place I keep talking about it.
Waterwheel is a pocket studio tool. Not a social app, not a subscription trap, not another RGB colour picker (actually colorlovers is great for that). It's for people who think: 'Look, is a new watercolour tube really so bad compared to a cup of coffee'.
All the bits:
Wheel - spin and compare outer and inner hues, read blend previews, and open manufacturer matches (Daniel Smith, Winsor & Newton, Schmincke, Sennelier, and more — 18 bundled catalogues so far). Warm/cool variants, harmonies, staining and granulation notes where the data has them.
Frame - camera study tools for the field: Claude Glass (circular value study) and a viewfinder with crop ratios. Handy for plein air and urban sketching when you want a second look at value and composition.
Palette - log what's actually in your paintbox and then go buy duplicates anyway, I KNOW WHAT YOU ARE. Catalogue colours or custom entries. Track what you're running low on.
Learn - short glossary and technique cards for when you're mid-session and want a distraction from overworking your piece.
Most of it runs offline on your phone (like, except the camera bit). No login. No friend lists. No data harvesting. You pay once ($4.99 AUD - less if you don't use Monopoly money) and that's it. You wouldn't believe how confusing it was finding how to do this in Google.
I'm an artist who wanted this for my own painting - not a studio, not a company. I made it because I needed a practical way to see which colours each manufacturer actually sells for a hue, and what to substitute when the tube I want isn't on the shelf.
If you paint in watercolour, sketch outdoors, or hoard half-empty tubes like the rest of us — it might be useful.

Questions welcome in asks/replies. I read them.
If you can't use Android, I'm sorry - it's Play-only for now - I'd love to do an iPhone version but I don't have an iPhone to test on. If you can, and you try it, I'd love to hear what works and what doesn't.
Thanks for being here!
