Show HN: Swap-a-Doodle, a cross-platform social drawing app

Hi, all. OP &#x2F; owner &#x2F; founder here.<p>I’m finally launching a product that’s taken me years longer than I’d anticipated to complete. It’s a much bigger project than anything I’ve done before. My first app was the first battery indicator on Android, back in 2009, which was very successful by my standards (I didn’t have a college degree at the time and made way more money from it than I’d ever made from a job.) I also have a free instrument tuner on the Play Store.<p>Swap-a-Doodle aims much higher, and was quite an undertaking for me. It’s a cross-platform app (Android, iOS, and the web) for social drawing. I knew nothing about computer graphics when I started out, and just a bit about web programming. I learned so much along the way. I’m sure I’ll learn a lot more as the app grows.<p>The front end is written in Dart. The back end is written in Go and runs on App Engine, with Compute Engine for the websocket servers for live drawing (sharing a canvas with a friend to draw together at the same time). The Android and iOS apps are fairly small wrappers around the web app.<p>Feel free to ask questions. I’m of course open to feedback, or I wouldn’t post here — but I do feel somewhat vulnerable in this surreal moment of finally launching, so please keep that in mind and try to be kind if you do have criticism, and maybe frame it as “something that could be even better,” if that’s not too much of an ask. Thanks!

Here&#x27;s an example of something really adorable made collaboratively by two people. The first person sent the first part to the second person, who used the Doodle-on-Doodle feature to add to it and make an even cuter story out of it.<p><a href="https:&#x2F;&#x2F;www.swapadoodle.com&#x2F;d&#x2F;5288420972691456" rel="nofollow">https:&#x2F;&#x2F;www.swapadoodle.com&#x2F;d&#x2F;5288420972691456</a><p>I think 9× is the best speed to watch it at. (I&#x27;m still thinking of adding a way for the author of a Doodle to change its default speed.)

Dude that&#x27;s awesome. Congrats! I like its simplicity and minimal interface, with no shenanigans. Just a plain ol&#x27; drawing app that lets you share. Great stuff :)

This is awesome. Fun and easy to pick up. Swapped-a-doodle with my technologically inept mom without a cinch. I was surprised how quickly she responded :)

This is cool and really easy to use! I love how it captures mistakes you make (the undo actions) when sharing it.

Fun! The basic feature feels like a cross-platform&#x2F;device way of doing the iOS Messages drawing feature.
