Translation Project

Friday, August 26, 2011

Make It 3D is becoming more and more popular around the world. At this time, Make It 3D have been translated into English, Korean, Japanese, and Chinese (simplified). I believe that there should be a lot of people who want to use Make It 3D in their own language.

  1. If you want to use Make It 3D in your language,
  2. And, you are familiar with English,
  3. And, you want to help people to use Make It 3D in your language,
  4. And, you are willing to help me translation project
Then, please click following link to download the English script.
Feel free to check the script out.

It doesn't need professional translations. Translation will be really nice if you are familiar with Make It 3D. For my case, translation took 1.5 hours.
I will pay $15 after translation. If you want to help this project, please contact me first at photo3d.apps[at]

Italian, German, French translations are needed ASAP.
Other languages are also needed.

Taking screenshot, Japanese language support

My Japanese friend already translated texts used in Make It 3D into Japanese before I released the app; however, a few days ago, I found Japanese texts were not included in the app. I am so sorry to all users in Japan (and my friend). Japanese texts are included in v1.34 which was released on today.

Another story, today, one of users pointed out that taking a screenshot is impossible because the screen of the app goes backward when the back key is pressed (DOWN) (Screenshot can be taken by pressing back key and power button simultaneously). That is my another stupid mistake. Changing screen backward should be done when the back key is released (UP). I haven't realized although I did have difficulties when I took screenshots (I did it anyhow). This back key issue will be solved in v1.35 which will be released in a week.

So, please send me email when you find weird things in the app. It helps a lot.
Thank you.

How much money did I make from the Android Market for the First month

Thursday, August 18, 2011

It is already been one month since I published Make It 3D on the Android Market. I think many people want to know how much money did I make so far from the Android market. So, here is my story.

For the first month (Jul 18 ~ Aug  17)
  • Total downloads: 6851
  • Active installs: 3205 (46.8%)
  • Average rating: 4.405 out of 5 from 42 users
  • Revenue from mobile advertising (admob): $3.88
  • PRO version sales: $3.99 * 18 copies =  around $72 (there is exchange rate issue) 
* For those who don't know my app
- Make It 3D is an Android app that makes anaglyph stereoscopic pictures

The number of downloads and active installs
6851 downloads for the first one month is not bad. The number of active installs is 3205. This number means 46.8% of users who downloaded Make It 3D still have it (53.2% of downloaders uninstalled it).


Mobile advertising (Admob)
Admob runs click-based advertising campaign. It means admob gives me money when user clicks the banner on the top of my app. I earned $3.88 from 92 clicks. It is around $0.04 per click. People said that it starts to make meaningful amount of money when downloads are over 200,000
  • Impression: 22,604
  • CTR: 0.41% (percentage of clicks over impressions)
  • Total clicks: 92
  • Revenue: $3.88

PRO version sales
Eighteen users bought PRO version so far. I made full refunds to the first four customers because I found huge bugs in the PRO version. Therefore, actual sales are 14* $3.99 = $55.86 and Google will take 30%. Since I blocked PRO version purchase almost 10 days (Jul 22 ~ Jul 31) to fix bugs, it is almost one copy per day. Not a bad record for the first month.

Income total
  • PRO sales $3.99*14*0.7 = $39.1
  • Admob: $3.88

Not big money. But, good thing is my download/active install rates are slightly increasing. I realized marketing is also very important. I am trying several tips to increase download rate. I will post these tips when it shows something.

Any suggestion or comments are welcome!

Next update for the PRO version (actually downgrade)

Sunday, August 7, 2011

Still, there are problems in the auto align function of the PRO version. I know what the problems are and what should I do.

The main problem is diversity of Android smartphone. It is almost impossible to make an app that can run all Android devices since every Android phone has different hardware (CPU&RAM) capacity. A function can be run on a device but it may not be run on other devices. On the other hands, for the i-phone development, if a function works on an i-phone, it will definitely work on all other i-phones.

The auto align function, the main feature of the PRO version, needs huge RAM. If 1600x1200 pictures are selected for auto align, required memory is more than 17MB (3[RGB]channels and 3[left,right,result]images) which is OK on my Galaxy S (and high-end devices). However, I am sure that some phones may not allow to use this amount of RAM.

I have struggled to solve this resolution related memory problem; however, my conclusion is that it is almost impossible to deal with all different devices for an individual developer (not a full-time programmer either) like myself. So, I decided not to support higher resolution (max 1600x1200). This is a disappointing decision for me too. But, I don't have any option at this time. I will lower the price too.

* Finally, I decided not to remove HD option.
