About a week and a half ago, developer Dennis Vogel introduced a Kickstarter campaign to raise funds for a Mac productivity application. And just as interesting, it's also a program that already exists.
Vogel is the developer of a number of useful apps for iOS (and even for the Mac), including the Index Card writing app for iPad and iPhone.
He is also the author of NumLock, an app that enables the number lock on the MacBook or Apple Wireless keyboard, turning 9 alpha keys into a block of number keys (the 7-9 keys are a part of the set). It's for touch-typing numbers as with a numeric keypad, which are available on full-size keyboards or as a stand-alone hardware option.
I have a working prototype of the app (unsigned) that I've been sharing with my friends. I'd like to make NumLock freeware and share it with the world, but need your help to make that a reality.
What the money is for: I'll donate my time to develop and support the app. Your backing will help cover out-of-pocket costs, including the following:
Membership to the Apple Mac Developer Program (required to sign the app)
Delivery of the app signed with a Developer ID certificate. This makes the app more secure, as the Mac OS X Mountain Lion Gatekeeper feature can verify that the app is not malware and has not been tampered with
Hosting of the app for download
Snazzy NumLockApp.com domain fees (easy to remember!)
Help desk and knowledge base hosting service fees.
He's more than made his original goal, but if you want to join in, please check it out here.
For an assortment of older Kickstarter campaigns with a Mac angle — all with less-than productive intent — there has been the Homeworld 3 game and the GlowWormz stickers for the MacBook Pro.
