About Us

Our Story

Our name comes from the Chinese proverb “行百里者半九十”: the last tenth of the journey takes half the effort. In that hundred-li journey, the final ten li are five kilometres — the stretch that gives 5KM its name. It’s a reminder to give the finishing touches the attention they deserve.

We bring that care to software: removing friction, refining interactions, and making small tools feel right, down to the last detail.

Our Mission

We create apps and AI skills that make everyday life easier, with care in every detail. We believe excellent tools should be:

• Minimal: Simplifying complexity for effortless use
• Efficient: Enhancing productivity and saving valuable time
• Comfortable: Bringing joy through thoughtful details

Our Philosophy

• Small yet Beautiful: Pursuing refinement over comprehensiveness
• Steady Growth: Maintaining rhythm like a marathon runner
• User-Centric: Polishing every detail through real experiences
• Open Sharing: Growing together with independent developers
