Built by Habit Lovers, for Habit Builders

We believe small, consistent actions are the foundation of every meaningful life change.

Our Story

Dail was born in Tokyo in 2024 when our founder Kenji couldn't find a habit tracker that was both scientifically grounded and genuinely pleasant to use every day. Every app was either too complex or too shallow.

So he built one. Simple enough that checking in takes 10 seconds. Meaningful enough that the data actually changes how you behave. Over the next year, a small team of designers, behavioural scientists, and engineers joined to build what Dail is today.

We're based in Meguro, Tokyo — a neighbourhood known for its quiet riverside walks and independent coffee shops. It's the kind of place that makes you want to build better daily routines.

Our Values

Six principles that guide everything we build at Dail.

✨

Simplicity First

Every feature earns its place. We remove friction relentlessly so tracking feels effortless.

🔬

Science-Backed

Our features are grounded in behavioural psychology and habit formation research, not trends.

🤝

Human-Centered

People are not machines. We design for real life — with setbacks, busy days, and imperfection.

🔒

Privacy Respecting

Your habit data is yours. We never sell it, share it, or use it for advertising.

🌍

Globally Accessible

Habits matter everywhere. Dail works in any language and on any budget — including free.

🚀

Continuous Improvement

We ship updates every week based on user feedback. We're always getting better — just like habits.
