I already have a fully-functional multi-function cooker driven by an ESP32. What is still missing is a polished Android / iOS companion app built with Blynk (or an equivalent low-code IoT platform) that lets users manage the appliance from their phone. Scope of work The firmware side is finished, so your focus will be the mobile layer: creating intuitive screens and linking them to the existing ESP32 endpoints over Wi-Fi or BLE. The app must allow real-time control of temperature, cooking modes and scheduling, while also displaying live and historical energy-consumption data. All features already exist in the controller; the job is to surface them beautifully and reliably in the app. Deliverables • Complete Blynk project file and source exported to my account • Branded Android & iOS builds ready for store submission • Clean, well-commented code / templates so I can extend features later • A short hand-off document explaining widget mapping, authentication, and how to change graphics or texts Acceptance criteria 1. Each target function (temperature, mode, schedule, energy) must read and write values to the ESP32 without lag or dropouts. 2. UI follows basic branding guidelines I will supply (logo, color palette). 3. Both platforms build without errors in their latest stable SDK versions. If you have previous Blynk projects that integrate with ESP32 hardware, let me know; it will help me verify that you can hit the ground running.
