Cross-Platform Price Tracker App

I need a straightforward internal app that lets our country managers key in current prices or a price range for every product we sell, then instantly makes those numbers visible to the sales team. The same code-base should compile for iOS, Android and load in any modern browser so nobody is left out in the field.

Core workflow
• Country Managers log in and enter or edit prices once a week or bi-weekly or as frequently as they like. Leave it flexible
• Sales reps open the app and see those figures laid out in a clean, sortable grid. They can flip the time selector to view prices for today, this week, or the last two weeks without downloading a separate report.
• No fancy analytics—just fast loading, clear typography and a search bar so a rep can find an SKU in seconds.

Tech notes
A lightweight cross-platform stack such as Flutter, React Native with Expo, or an Angular/React SPA plus a small REST-ful or Firebase backend will suit us fine; I am open to your preferred toolkit as long as deployment to the App Store, Google Play and a web sub-domain is covered.

Deliverables
– Source code and build instructions for iOS, Android and Web
– Simple admin panel for price entry and user management
– Grid view with filter by day / week / bi-weekly
– Authentication tied to our company email domain
– One-click export to CSV for finance

Hand-off is complete when I can install the mobile builds on test devices, open the web version in a browser, and verify that a weekly price update entered from the admin side shows up immediately in the sales grid. Show More
