Read full descriptionHide full description
Flux is a system insights app for people who care how their device behaves over time. Instead of live dashboards and constant numbers, Flux focuses on patterns, drift, and change β the quiet signals that usually get lost in real-time noise. Track how your device evolves throughout the day and across longer periods, with carefully designed visuals that prioritise clarity over clutter. What Flux shows you: - Battery behaviour and long-term drift - Connectivity changes (WiβFi, cellular, Bluetooth) - Thermal state patterns - Background activity trends - Timeline-based system events Designed to feel different: Flux avoids the typical system monitor aesthetic. No flashing charts. No aggressive colours. No unnecessary alerts. Privacy-first by design: Flux does not collect, track, or sell your data. All analysis happens locally on your device. Built for today β ready for tomorrow: Flux is designed with future features in mind, including widgets and deeper long-term insights, while staying fully compliant with Appleβs platform guidelines.
