about haenaegi

Haenaegi is a small app made to support calm, focused study sessions. It does one thing well: helps you stay with your work. Your timer syncs seamlessly across Apple devices, so you can start on your iPhone and continue on your iPad or Mac without thinking about it.

Haenaegi started as something mingeee built for himself. It began as a simple experiment—a way to explore whether a timer, thoughtfully designed and carefully crafted, could be something people would actually want to use. What started as a small personal project slowly became the app you’re using today.
