Hey Product Hunt! I'm Mateusz, the maker of Calma Color. Calma Color is a color-by-number app for a quiet break. Each tap fills a numbered area with color, a soft ASMR sound and gentle haptic feedback. You can add rain, ocean or a campfire in the background, or switch the sound and haptics off. A few things to try: - Pick a cozy illustration and choose Calm, Balanced or Deep detail. - Turn a photo into your own coloring page. Processing happens on your phone; your photo is never uploaded. - Replay a finished piece and share it as an image or a short video. No account is needed, and you can color offline with artwork already on your device. There are no streaks to lose or timers to beat. It's free to start on iPhone and Android. The free version has ads outside the coloring canvas. Premium is a one-time purchase that removes all ads and unlocks the standard library, standard sounds and unlimited photo pages. If you give it a try, I'd love to know: how do the sound and haptics feel on your phone, and what kind of artwork would you like next? Thanks for taking a look. I'll be here to answer questions!
