Petr Nálevka is the founder and lead developer behind Urbandroid, a small Prague-based Android app studio known for practical health and utility apps. Over the past decade he has focused on software that helps users sleep better, manage circadian rhythms and reduce nighttime screen glare. His best-known title, Sleep as Android, combines a smart alarm with sleep tracking, snore detection and integrations for wearables and home automation platforms. Twilight Pro and Mindroid PRO Unlock round out a concise portfolio that targets mobile wellbeing and app monetization needs.
Urbandroid’s work is notable for user-focused feature sets and long-term support rather than flashy marketing. Sleep as Android has been adopted by millions and is frequently cited in discussions about smartphone-based sleep tracking and anti-snoring tools. Twilight helped popularize blue-light filtering on Android before that feature became common in system-level settings. Petr maintains an active presence with users via the community page and support email ([email protected]), and continues to iterate on existing titles rather than pursuing a broad product catalogue.
