About

Keru

Read full description

Most habit apps make you feel behind. Keru does the opposite. Every morning, Keru gives you one intention. A single, concrete thing to focus on today. Every evening, you check in. That's it. No streaks. No scores. No guilt if you miss a day. Just a quiet, daily practice that helps you move in the direction that matters to you. How it works Choose a focus area, something you want to work on in your life. Keru uses AI to suggest three intentions each morning, tailored to your focus area and where you are in it. You pick one, or write your own. In the evening, you reflect. Did you show up? Did you try something? That's enough. Your Journal Every intention and every reflection is saved in your Journal. A personal record of the small steps that add up over time. How Keru is different Most productivity tools reward output. Keru rewards presence. It's not about doing more, it's about doing what matters, one day at a time.
