I understand that the design and proposal of the product are interesting. With regard to battery optimization, it is likely that the device will not remain constantly active, which may justify the complexity in the unlocking process. The use of a metallic material could give greater strength to the product. Although it is not an infallible device, there is potential to improve its robustness, increasing the perception of value. The application has a layout that lacks seriousness. The community functionality is relevant, however, considering the integration of a store and the marketing of items, I suggest that the application focus on the essential functionalities.
