Idea to app store in just 1-day.

With over 140,000 users and zero ad spend, instaspacer is an example of how product/market fit happens when you think about solving small problems that matter, well.

Instaspacer for instagram

The problem

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.

Existing solutions

At the time, tools existed on the web, and we found out users wrote captions into their phones, copying and pasting text across apps. We found it users were frustrated with this experience and wanted something simpler.

Our solution

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 1-day to build the basic app on both iOS and Android, so we opted for Flutter as our development framework.


The outcome

Within a few short months instaspacer has found itself on over 140,000 active 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.

Below is an example of content created about instaspacer by the community.
