We decided to build a simple MVP, focussed on solving just the core problem, with no other features. We set a tight timeframe of just 2-days to build the basic app on both iOS and Android, so we opted for Flutter as our development framework.
Instagram users LOVE their captions. It's a space for them to express what their photo is all about. But, they cannot add whitespace to create the look they want. So they resort to using dots, dashes and other ugly to characters to push their hashtags away from sight.
Within a few short months instaspacer has found itself on over 300,000 devices and users keep it on their phones 80% of the time, which is an incredibly high rate.
Zero has been spent on marketing and advertising, yet the app continues to grow due to the amount of sharing it receives from its social audience.
Solve a real small problem, very well. Don't worry about lots of features. Find the core.
Improve something that exists already, but remove the friction from the experience.
Products that have product/market fit sell themselves with little effort.
