СметаПросто is a productivity application designed for construction professionals, including craftsmen and small teams like electricians and plumbers. It enables users to create estimates directly on-site using their mobile devices. The app allows customization of pricing and volume inputs, automatically calculating totals for various projects such as apartment renovations and roofing. Users can access a built-in directory of tasks and prices, ensuring they can input their own pricing or select from pre-defined tasks for accurate estimates.

The application offers features such as project-specific estimates, client management, and the ability to provide discounts on estimates. Users can save and send completed documents directly from their phones, including their company details. The app operates offline, allowing access to project data without an internet connection. A construction calculator is included for volume calculations, while a subscription model is in place for continued use beyond the first month.
