Sorry, submit where? I don't get what you mean by submitting, you mean on HN? Doodledocs is the only one. Apps I've made over my lifetime are a lot less than I'd wanted to but here they are:

1. an ios app called Wordpin (I made it for a person who really wanted it)

2. an ios app called SIVT (psychology research thingy, it was a lot of fun)

3. A computer graphics engine (2012, still one of my best memories, Doodledocs is a close second): https://www.youtube.com/watch?v=PH6-dLvZEiA -- it was for a course but I spent a lot of time in it

4. Unfinished things like: https://melvinroest.github.io/Interactive-Neural-Networks/

5. Way too many scrapers (I like data), the most fun one was a scraper that scraped a website in order to get a restaurant reservation (it was really tough getting in and I knew a foodie who really wanted a reservation there and I wanted to try out Selenium for any excuse imaginable)

6. Some games: one in Unity3D, one in GameMaker (with the scripting engine obviously) and one in Game Salad

7. A lot of websites, small websites most of the time but they add up. I remember I made a CRUD app that tracked all hackathons in The Netherlands. I liked making the app more than tracking all the hackathons.

I suppose that's about it.

Oh, 8. Doodledocs.com
