My app has gone viral and I grew from 1k users (take 5months) to 100k user in 5 days

I've always dreamt of building an online side business where I can build once and sell to millions. I love that business model but have never dreamt that I can achieve that, given that I am not a programmer in my career. I have been following side hustle school and some other business podcast for the past years as a drive and motivation to create my own business. 

Over the years, I've delve a little on to web development using WordPress and in the hope of earning some money from that. I learnt in the hard way but is a good learning story and journey. I realised that what you put all your efforts building and excited for doesn't mean anything for anyone else and also learnt the importance of UI UX. 

Fast forward to 5 months ago (July 2024), I've came across several low code app builder. With the help of the low code tools in combination with chatgpt, I've finally launched my first mobile app - Rolly: AI Money Tracker.

But the business challenges doesn't end here, but it's just the beginning. I got no experience and skills on marketing but I've got my drive and passion that keep propelling me forward. By keep listening on people sharing their journey, looking at different apps to brainstorm etc, I've managed to now grow my user base from 1k (in 5 months) to 100k (in 5days). What's happening was my app somehow got viral in Vietnam when people are getting interest funny comments from my AI during entering the transaction and it has been sharing around in the social media and even featured on the news. What a crazy journey as the inflow of users has been too sudden, my server has been down for a few times until I progressively upgrade it until it got stable these couple of days.

As for my advice to people dreaming the to be entreprenuer - Don't overthinking about all the problems you will face before starting. You will encounter hundreds of problems along the way and you just need to solve them one by one. You will never start if you think about what's not working and there will never be an answer for everything - even I don't have an answer for everything now.
