Need a mobile app icon set designed in one consistent style

We're finishing the interface of a mobile application and need a complete set of icons used across every section — navigation, settings, profile, notifications, and the main functional screens. Right now the app uses a mix of icons from different sources, and it's starting to look inconsistent: stroke width, corner radii, and visual weight all differ from one screen to the next. We want a single, cohesive icon language, so the product finally feels like one designed thing rather than a patchwork of borrowed pieces.

The set needs to support both the light and dark themes already built into the app, so every icon should be prepared as two versions, or designed to adapt cleanly to both backgrounds without losing contrast at small sizes. We also need files exported and organized for direct use in development: correct raster sizes for the platforms we target, plus editable vector source files so icons can be resized later without redrawing from scratch.

We're open to discussing the number of icons, reference styles, and the tool you prefer, but by the end we expect:

— a unified visual style across the whole set (line weight, grid, corner rounding);
— separate light and dark theme variants for every icon;
— clean export in platform-ready sizes plus editable vector sources;
— files organized and named clearly enough to hand straight to developers.
