Thumbframe

Read full description

Thumbframe turns your iPhone or iPad into a sketchbook for app ideas. Screens are stacked, not drawn: pick ready-made blocks like a navbar, a list or a tab bar, and they snap into place. Nothing to align, no pixels to push. BLOCKS, NOT PIXELS • More than 40 blocks for real app screens: navbars, lists, cards, forms, sheets, dialogs, tab bars and more • The first tap picks a block, each further tap goes one level deeper • Shared components keep a tab bar or a header the same on every screen STATES AND LINKS • Variants hold the states of a screen (empty, loading, an open sheet) and store only what changes • Link buttons and list items to screens or states • The preview turns it all into a clickable prototype HAND IT OVER • Share a screen as an image • Export a spec in Markdown that describes structure, states and navigation, ready for your team or a coding agent • Share a clickable HTML prototype that runs in any browser • Or everything as one package, together with the project file PRIVATE BY DESIGN • No account, no cloud, no tracking • Your projects stay on your device; export them as a file whenever you like Thumbframe is made by Studio Merkas in Stuttgart.
