Nullun – Battery Screen & Status Bar Studio

Nullun is an Android app for creating customizable battery screens and status-bar visuals for entertainment, creative posts, conversations and social content. Set any battery level from 1% to 100%, choose Android- or iPhone-inspired styles, switch between Normal and Low Power modes, add ready-made or custom messages, and preview the result before export. Nullun Pro adds Status Bar Studio with controls for carrier name, LTE/4G/5G, signal strength, Wi-Fi visibility, synchronized battery information, app name, notification text and premium backgrounds. Creations are generated locally on the device. Pro is a one-time purchase with no subscription. Why do startups need this tool? Nullun helps founders and creators prepare controlled battery and status-bar visuals for product presentations, tutorials, social content and creative mockups. Instead of relying on whatever battery, signal or notification state happens to be visible, they can configure those visual details intentionally.
