Ask HN: What did you build or launch in April?

We've had a lot of fun in the past showing off your current projects. Folks get some publicity, some feedback, and some ideas for their own projects. So, if you built or launched something in April, here's your chance to show it off with a description and maybe a link. I want to read about what you've done this last month!

  • My co-founder and I launched our progress tracking tool for educators. It allows teachers to print out assignments that can be scanned via fax. We do the scanning and grading on our end automatically and spit the results out in analytics.

    Check it out at http://kiteedu.com !

  • We launched http://dialog.gs/ into private beta a week ago.

    Dialoggs is a social conversation network that can be used in a number of ways. See my explanation at http://amirmalik.net/2012/04/27/introducing-dialoggs if you're interested.

    With ~100 users (~20 active/day), it's been great iterating on the product and seeing user feedback first-hand. Our app is incomplete with obvious bugs, yet we still launched. People love it and understand that we're human, and it's still a work-in-progress.

    Don't wait for perfection that may never come, just launch.

  • I opensourced a ruby-based bulk domain look up tool just like LeanDomainSearch but designed for home user. http://github.com/joenorton/domainblob

  • The Personal MBA Guide to Small Business Infrastructure

    https://infrastructure.personalmba.com/

    I wrote the guide, produced the PDF using a nice third-party template with a few custom modifications, and wrote the entire sales app from scratch. This project is the first time I've used Stripe and Mailgun. The entire project took less than a week, and is on track to net five figures in the first month of sales.

  • Lanched pgXplorer (http://pgxplorer.com). pgXplorer is an open source desktop GUI client for PostgreSQL database.

  • Released http://irepl.im (Scheme REPL for iMessage), and then started to work on a more serious side project of mine http://mathwake.com

    Quite like the idea of this thread - I've started to try and release something every two weeks until I find something that I really want to put all my time into.

  • We launched our iPad travel magazine, Overnight Buses Travel Magazine. iTunes link: http://itunes.apple.com/us/app/overnight-buses-magazine/id49...

    Its a long-form travel magazine. Our second issue is coming out in July and next up is gaining some advertising. Should be fun.

  • Added Siri support to my Reddit Notifier app for OS X:

    [Mac App Store]: http://itunes.apple.com/us/app/reddit-notifier/id468366517?m...

    [video]: http://www.youtube.com/watch?v=oDQfqpzQfLA

  • I moved a couple of thing that were tools on my own site onto their own domains. Both just fun projects, but still, they made it out of my brain and into the world :)

  • Major redo of http://www.onehandkeyboard.org/ ... Wordpress, blog posts for patio11-style content generation, etc.

    Also shipped a much-improved version of the Mac app itself... but that's still waiting for review from Apple. So I suppose that doesn't count for April :0

  • Started working on and launched Everyminder, a web app to handle infrequent maintenance tasks I always forget about: https://everyminder.com/

    It's currently pretty basic, but I have lots of neat stuff on my todo list -- should be a fun ride.

  • It was my first project! Nothing big really, just a little 1 MB windows form in VB that streamlines making an internal template. Still, it's exciting to make something my coworkers appreciate.

    (I don't have it anywhere to share, and since it's VB I'd be a bit ashamed to, sorry)

  • I played around with the OpenTok API (http://www.tokbox.com/opentok/api) and built Chat Envy: http://chatenvy.com

  • I started a company that names new startups and products - http://www.nomvilla.com. It's going okay so far, but I'm working on a name-logo-business card package.

  • I started learning D3 by recreating Tufte's epic "2004 MLB Baseball Season" graph.

  • Just launched Briarpatch yesterday (a way to share and follow bookmarks): http://briarpat.ch/hot

  • I've opened Hevibyte to new sign ups. It's secure sneakernet. http://www.hevibyte.com

  • We have launched Wifi Protector - www.wifiprotector.com , super-easy to use VPN service to protect you on unsecured networks. Any feedback?

  • Soft launched http://traxmo.com - time tracking, task management & invoicing.

  • Soft launched http://mindcast.com -- spatial memory and bookmarking system.

  • www.dabble.it - A location based journal. Leave digital postcards wherever you are. iPhone and Web app
