Figma
Mobile Wireframe UI Kit

Mobile Wireframe UI Kit is a Figma freebie.
The Mobile Wireframe UI Kit includes a complete set of medium-fidelity components for mocking up mobile app ideas. It covers Android and iOS UI elements like nav bars, tab bars, keyboards, alerts, inputs, FABs, and more. A Kalam handwriting font version is also included for lower-fidelity wireframes. Great for ideation, prototyping, and team alignment before investing in full designs.
Before you start: To customize iOS components, you’ll need to install SF Pro from Apple.
