To make your smartphone more handy

[Author]
Egg-On-Egg.com was founded in 2011. It has provided unique and useful apps since then.
I want to extend a big thank-you to all customers.

Now I think the Egg-On-Egg's mission has been accomplished, and have desided to provide all works for FREE.

Each Egg-On-Egg's app has been refined on a steady basis, so I beleave you'll be satisfied using them still now. Let me know good news and bad news about the apps from here on out. I'm looking forward to seeing it :)
