Lumo is a minimal iOS app that reflects your screen time through mood and atmosphere — not charts or warnings. It doesn’t block apps or tell you what to do. It simply shows how your phone usage feels, so you can notice your habits without guilt. No numbers. No pressure. Just awareness.

FocusRise turns your focus time into a living city. Unlike traditional focus timers that simply count minutes, FocusRise visualizes your consistency by creating buildings for every completed session. What makes it stand out? • A uniquely visual reward system — your city grows as you stay focused • Failure is visible too — unfinished sessions become half-built structures • A calming, minimalist UI designed to reduce friction FocusRise makes focusing feel productive, tangible, and personal.
