I need a simple, cost-free Android application that lets me point my phone at any supermarket barcode and instantly see three pieces of data pulled from an Excel sheet: the quantity I still have on hand, the current selling price, and any ordering details I have stored. The app must work entirely offline while I’m on the shop floor; I’ll only reconnect when I swap in a refreshed dataset. Here is the flow I’m after. I export my stock report every morning to Excel, drop the file into a predefined folder (or upload it through a small admin screen), and the app overwrites yesterday’s data. When a barcode is scanned, the item record is located locally and the three fields display in a clean, readable layout. I’m open to any no-code or low-code platform—AppSheet, Glide, Kodular, MIT App Inventor, or something similar—as long as you can hand over the editable workspace so I can maintain the project myself. I selected Natural Language Processing as the preferred AI add-on because I’d like the option to query the database by voice later (e.g., “How many packs of spaghetti are left?”). A basic implementation or a clear path for that capability will be appreciated. Deliverables I expect: • The Android APK and the editable project file from the chosen no-code platform. • A short guide showing where to place the daily Excel file and how the columns map to the three displayed fields. • Any custom scripts or functions you create so I can build upon them for future voice-query features. If you have built similar barcode or inventory tools, let me see a quick demo come with ready platform and build simple program within 2 day
