Chalkee is a home screen widget app that lets users draw chalk-style messages for each other, appearing directly on the recipient’s lock screen. It launched five months ago and hit 10K downloads last month, currently sitting in the Top 100 for Social Networking across 30+ countries.
The entire content strategy runs through two Instagram accounts and one format: a dual-screen demo showing a message drawn on one phone appearing instantly on another.
They don’t need to use their faces, or to hire creators. No faces, no creators, just two lock screens and the moment the message lands.
We covered the same format when it drove Lovelee to 21.8M views and Lovio to 42M. Chalkee is running almost the exact same playbook.
The first account, @ponta_apps, launched in February posting entirely in Japanese. It accumulated 9.8M views and validated the format before the team pushed it to a wider audience. The breakthrough came on March 6, hitting 3.1M views with a hook that translates to “my friend’s morning. how to make it a little better.”
The tutorial shows a message written on one phone appearing instantly on the other. The whole concept lands in two seconds.
A few months later, the English account @chalkee.app launched in May. In barely over a month it has already crossed 9.1M views, outpacing the Japanese account’s total in a fraction of the time.
The hooks shifted too. Where the Japanese account led with a tutorial angle, the English account leads with emotion. “I just wanted to be the first thing they see today” hit 3.5M views on June 5.
“They were thinking of me and I didn’t even have to ask” hit 4.8M views on June 11.
The format stays the same across both accounts. What the English account added was an emotional hook to sit on top of it, and that combination traveled faster than the tutorial angle ever did alone.
Running the concept in Japanese first, then moving it to English once the format was proven, is not something most apps think to do deliberately. Chalkee’s numbers make a case for it.
