Nullun focuses on fast, detailed control without unnecessary complexity. It combines battery levels, power modes, ready-made or custom messages and a configurable status bar in one Android app. Users can preview changes before export, save results to their gallery, reuse recent creations from History, and unlock Pro with a one-time purchase instead of a recurring subscription.

Android users, social media creators, content creators and anyone who wants to create customized battery screens and status-bar visuals for entertainment, creative posts, conversations, mockups or social content.
Nullun by TSI Dev Studio's answer
Nullun was created around a simple idea: small details such as battery level, carrier, signal, Wi-Fi and notification text can completely change the context of a screen. The goal was to make those details easy to configure in one focused Android app, while keeping the workflow fast, local and simple.
