    I’m looking for a straightforward mock-test app that my students can open, select a test, and start answering Multiple choice questions. Each test must be timed (I chose “Yes” for timed tests), and once the countdown reaches zero—or the student hits submit—the app should immediately display their overall score, a breakdown of right and wrong answers, and any explanations I provide. Because I selected “No, feedback at the end,” nothing should pop up after each individual question. The interface can stay minimal; speed and clarity matter more than elaborate graphics. A simple way for me to upload or edit the question bank (CSV import, small admin panel, or even JSON in the code) would be very helpful, but I’m open to whichever method you can b...

The project is strictly for iOS, so everything—from the UI layout to payment handling—must follow Apple’s Human Interface Guidelines and the latest App Store policies. I already have a product catalog and basic brand assets; what I need now is an end-to-end native solution in Swift.

    I need a single, integrated application that lets me run both sides of my business—restaurant and retail—from one place. The must-have features are real-time stock management, streamlined order handling, and clear profit tracking. The system has to process both restaurant tickets and shop orders seamlessly, including bulk requests. For fulfilment I rely on in-store pickup and a simple delivery workflow, so the app should coordinate pickup queues, assign drivers, and update delivery status in real time. A dashboard that shows live inventory, automatic deductions when items are sold, low-stock alerts, and daily profit snapshots will complete the workflow.

    Hi there! Hope you're doing well. I have a hobby-grade RC truck (thinking Traxxas Stampede or a similar 4WD model) and I'd love to turn it into something I can drive remotely over the internet — not just the usual short-range radio control, but actually control it from another country, with minimal delay. The basic idea is to swap out the stock RC receiver for a Raspberry Pi (or something similar), so instead of a normal remote, I could control it through a simple web page or app from anywhere with an internet connection. A few things I'm hoping you can help with: Getting the Pi talking to the truck's existing motor controller and steering servo Setting up a low-latency connection (something like WebRTC) so the controls feel responsive even over long distances A s...
