2018/6/7. 3rd app... What should I make for 3rd app? I have some ideas for making apps. But what ideas is fun for me to make them?  I don ’ t do games on iPhone. Paradoxically , Games for who doesn ’ t usually play , are good ideas...  Or tools for stock investment , such like ICHIMOKU clouds , are better. But it is difficult. Or tools for construction workers , are better.  I don ’ t know what app will be great sales. So making my mind is difficult... And fun of making is more than great sales , maybe this is right.

2018/6/6.  Second App I am making second app , and it is almost completed. My second app is for Japanese workers ’ tool. And making this app takes 1 week or shorter than it. My development skill is growing up. But iPhone vs Android phone... I hope swift language can be useful for Android Phone. This movie shows that Android phone is almost better than iPhone... https://youtu.be/YMQn4bAFq8E

2018/6/5. WWDC 2018 I watched about WWDC 2018 news. Swift Programming Language will be major one. This language will be used both of macOS & iOS. This means the ratio of learning cost/reward will be lower. Or return from learning Swift is bigger.  This is what I imagine. Learning Swift is more than other machine language. Learning cost is low , and return is high. I recommend learning Swift is good investment in 5-6 years , or more. And in near future , programming is vital skill. Some people study about traditional subjects in coffee shops , but I think only 3 subjects is to study... Programming , accounting & foreign language , especially English or Chinese. I started studying from English , and then , programming. Recently , I want to start studying accounting ( Not difficult one , but for small business. ) . There are many subjects , and smart people try to take all. But focusing on programming , accounting and foreign language will be be...

2018/6/4. Avoidable competition  I am making next app , and thinking about competition. I think that competition is not to fight , but to avoid. I wonder if this is right. Some people may think this attitude as bad. But so what? In reading “ Zero to one ”, I have conviction about it. Competition makes us tired. Of course , users get benefits from competition. And users want competition situation will be kept longer.  If I want to create something , I should target monopoly situation. Monopoly is opposite side of competition. And how to get monopoly , focusing on it is more important than fighting competition.

I changed my app "Word On AR World" icon from left one to right one. Maybe some people like right one. Left icon is too artistic...

2018/6/2.  Why Bank of Japan is buying ETFs? Additional explain for my opinion… Bank of Japan ( BOJ ) is buying a lot of government ’ s bonds & domestic stocks ( ETF ) . I know buying government ’ s bond by BOJ is very dangerous for the trust of Japanese Yen. And if the trust is lost , hyper inflation is caused. Hyper inflation causes stocks ’ price higher. And if government is bankruptcy , hyper inflation is caused , too. So offsetting the hyper inflation ’ s effect is buying a lot of ETF and defending trust of BOJ. Also , defending big companies to be bought by foreign companies is additional purposes.

2018/6/2. Start Reading “ 0 to 1 ” A lot of people are tricked by some rumors , and I am , too. There are some truths which people don ’ t realize or believe another myths. In Japan , the government uses two tongues , one says the government doesn ’ t bankrupt , another says the government is suffering from short of income , so raising taxes.  What can I read from these attitudes? I feel only untrustworthy to the government. But I start to rethink about government ’ s debts. Limit of government debts https://creating-favorite-opinions.blogspot.com/2017/10/limit-of-government-debts.html?m=1 In this blog , Japanese government bankruptcy will be 2023. When total debts are over ¥1600 trillions , it will come to the end. Now total debts are ¥1100 trillions , and it took 18 years for increasing ¥500 trillions. The speed of increasing is faster than past. So I estimate 6-9 years later to the end , 2023-2026. And Bank of Japan will be ready for hyper ...

2018/6/2. Next app , I wanna make... My first app “ Word on AR World ” is available now. I don ’ t think it will be used by a lot of people. But okay. Maybe a lot of companies target on AR app. I don ’ t want to compete with them. Next app I will make is for Japanese construction people. Simple app. There are various testing methods to build asphalt roads. So I will make some tools for the methods.

Finally, my app is available on App Store! Yeah! This one step is small, but big for me!

2018/5/31. Rejected... My app was rejected because of low perfection. I know Apple ’ s judge is right. Machine language is not easy...

2018/5/30. AI never be my god... I feel that AI never be my god. I mean that AI never be perfect method for my happiness. I learned a few about AI , and I feel so.  But learning machine language ( i.e. Swift ) will be gold wing to be success. People who worry about future , have to learn machine language. Learning Swift is less costly than learning Chinese , Russian or Arabic languages. And rewards from Swift is more than learning them.  Learning Cost/Reward is important. #I am waiting Apple review for my first app... I hope it will be accepted...

2018/5/29. World economy: Some signals about disaster , but not enough... There are some signals about economic disaster , world real estate , USA subprime car loans and government bonds in EU. 1 ) World real estates Some big Japanese companies started to buy foreign real estates. They know the price is high. 2 ) USA subprime car loans This type of loans are hit by interest rates hiking directly. 3 ) Italy government bonds  There are problems about government ’ s huge debt. I focus on Japanese companies ’ action. Because Japanese interest rates is lowest in the world for long term.  I think it causes the delay for catching up to World movements. ( I cannot explain this phenomenon well. )   Slow action causes lowest interest rates or lowest interest rates causes slower action , I don ’ t know which is right. But this delay is critical  to be end buyers. ( End buyers:People who buy things at highest prices. Losers in market. ) ...

2018/5/28. Rejected... My app “ Word on AR World ” was rejected. Okay , I will retry after iOS 11.4 is released. And I realize that AR app has good combination with movies.  AR tool apps which is useful for YouTuber , I will make them! I am making next new AR app , now!
