I built Nullun around a simple idea: small status-bar details can completely change how a screenshot or visual feels. With Nullun, you can set any battery level from 1% to 100%, choose Android- or iPhone-inspired styles, 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, synchronized battery information, app name, notification text and premium backgrounds. Everything is created locally on the device. There is no subscription — Pro is a one-time purchase. I’d love to hear what you think, especially which status-bar controls or creative use cases you’d like to see next.
