It is not that bad …
think about density groups

Android OS versions
Each previous major version support would cost you at least +20% of time (applicable to iOS too)

It should be different

How much is that to build
• Core functionality can be done for 40% of time, features will eat the rest (animations, shadows…)
• Effort is approximately the same for iOS and Android
• Do one after another instead of 2 at same time
![Page 31: 10 things to consider when choosing a mobile platform (iOS or Android)](https://reader035.vdocuments.us/reader035/viewer/2022070302/547dc05e5806b5b35e8b45e2/html5/thumbnails/31.jpg)
Conclusions
• Sometimes it may be worth to start with Android
• In many cases iOS is still a platform of the first choice to prove your concept
• It may take a lot time, so select wisely…
