I want a straightforward flashlight application that runs natively on both iOS and Android. The core requirement is general brightness in steps control handled through a single button operation. The light will start off at the dimmest level and, with each button prese, increase brightness. Up to 5 steps will be used. A simple voice command hook (e.g., “brighter”, “dim”, “off”) would be a welcome bonus if it can be implemented without bloating the build. Beyond brightness, the only extra I need is a timer so users can set the light to switch off automatically after a defined interval for each brightness period. In addition, there is a user programmed timer. For example, a user presses and holds the button. The light will stay on for a second and then flash. Continuing to hold the button another 4 seconds after the flash and then release will keep the light on for 5 times that period, so 20 seconds in this case. SOS and strobe modes aren’t necessary at this stage. Please keep the interface is basically a single button use similar to the BeeBRT flashlight that is being developed. More details on this after NDA signed. Minimal: one main screen with the button, and (if feasible) a small mic icon to trigger voice control (such as "button push and hold for x seconds". Feel free to choose the framework—native Swift & Kotlin, Flutter, or React Native—as long as performance is smooth and both stores will accept the submission. Deliverables: • Compilable source code for iOS and Android • Release-ready builds (TestFlight and APK/AAB) • Brief setup/read-me so I can recompile, adjust icon assets, and publish The app is simple by design, so code clarity and quick start-up time matter more than fancy visuals. I would like to make this as an app that will either have a monthly subscription or a one-time purchase cost as well. If purchased or even downloaded, I would like to obtain a valid email for later marketing use. In terms of revenue, I am willing to share 10% app store revenue in exchange of lower app cost development.
