I need to develope an Android application prototype for my project.
I am planning to create a saving goal planner which can calculate either 1) how much do I have to save per month to reach the goal? or 2) How long will it take for me to reach the goal given my monthly saving budget. The annuity formula for future value will be used for the calculation.
For more details, I have uploaded 'formula and design example' document and sample excel calculation for this application.
Lastly, I need developer who can comfortably communicate either in English or Korean.
