Byaj Book – Interest Calculator, Loan Management - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?


What was the most challenging aspect of developing mobile app?

Just as the world is not small, the same in the case of mobile apps. You have plenty of things to choose from before starting. There are numerous development frameworks and platforms to choose from. Sometimes it becomes difficult for developers to choose the right option. We wanted our UI to be so simple and elegant that anyone from 13yr to 65yr can use it easily without any hurdles.

We are a Bangalore-based startup consisting of three friends, graduated from IITM in Computer Science in the year 2019.

Name a few of your favorite apps and reason you love them.

Instagram , unique idea and simple UI.

How long have you been working on this app?

2 months.

What need of the user did you have in mind when developing this app?

Often we give loans to our friends or colleagues when needed but either we write it in a notepad or save it somewhere on phone, which can be easily lost or even one can forget about it after some time. We wanted to overcome this hurdle of managing informal loans and get timely interest on them.

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

With ByajBook, users can manage their private loans or debts with friends, family, and colleagues. We provide an integrated interest calculator and also automated SMS and reminder notifications. Our biggest strength lies in our simple-to-use UI and the fact that it's 100% Free. We have made our digital ledger two-way where both the involved parties can see the loan details which stands out amongst the other apps in the market. We are very proud that in a very short span of time, we've made it live on the play store.

What are your future plans and expected features of the coming new versions of this app?

We are working on our IOS store listing and adding automated payments via the UPI option.

Assuming new users of your app are reading this page. What do you want to ask them to do (contact you about X, Share the app, etc.)?

We want honest opinion from our users which will drive us to work hard towards achieving our goal. If users can rate us on the Play Store or share the app with friends and family, it would be of great help.
