The previous Advanced Tip Calculator is simply an extracted version from the Advanced Financial Calculator. It doesn’t have a good usability. So I redesigned the tip calculator over the weekend and release it as donationware. There are both free-ads-support version “Tip Calculator Donation Free” and paid version “Tip Calculator Donation”. The ads revenue and sales revenue from both apps will be COMPLETELY donated to some non-profit/charity organizations to help people in need (such as fighting with AIDS or cancer, post-catastrophe reliefs, helping people in poor countries). And I will post receipts with the amount when it happens.

It was a great day today. Just in one day, we sold 27 copies of apps. For many other popular apps, this number is way too small. But for us, it was a great improvement. Most of the sold apps are Advanced Ruler Pro because we just released an minor update this morning. As the only camera ruler on the Android market, it certainly has the advantage.
Starting with the first app Advanced Financial Calculators, it was a bumpy ride to sell on Android market. The Android market is much less mature than Apple store. The infrastructure is not very good. Developers cannot even view their own paid apps’ comments if they are using a dev phone. No real-time statistics update, no reporting tool, no proper way to response to users’ comments, 325 chars limitation to app description. And the most importantly, the market size is much less than Apple store. After a few days after I realized the reality, I treated the dev. work as doing something fun rather than making money. However, I do have a believe that one day Android market will pass the Apple store because of the openness of Android platform, just like PC passed Mac many years ago. That’s when Android developers can really seriously make money.
I also want you know, the sales from all our apps till the day before yesterday (about two month period), excluding the 30% taken by Google, has been donated to Jet Li One Foundation which will be handed over to the victims of China Yushu Earthquake, a 7.1 earthquake with a stunning death toll of more than 2200, leaving thousands of people homeless in an extremely cold place. Those people need the money most. You can find a receipt below. I covered the amount as I am not ready to disclose how much sales we made so far. But if you purchased our apps in the past 60 days, you know that your money is on their way to help people. Let’s wish one day that they can build stronger buildings which will not collapse and innocent students will not be buried.
