What's the story behind your product?

Belly Clock's answer:

As a Muslim, I fast a few times throughout the year. However, I've never come across an app that caters to Islamic fasting or more especially, tracks the different times of the Islamic Calendar when a person should fast. I wanted something comprehensive for myself with the hope of helping other Muslims enjoy their journey too and encourage them to fast beyond the obligatory days. Why not throw in other fasting methods that most apps and websites don't cover?

Which are the primary technologies used for building your product?

Belly Clock's answer:
