Get freedom from your phone’s obvious limitations. Use Proto.io, made by Proto.io, a Productivity app on your PC or Mac with BlueStacks, and level up your experience.

Proto.io’s mobile viewer feels like a clean, straight-to-the-point way to check prototypes without hauling around a laptop or opening a full editor. It loads shared projects fast, and the new layout is easier to understand at a glance. The big win is the On this device section, which replaces the old offline switch. Now it is obvious which prototypes are saved locally, so testing still happens when the connection drops, on the train, wherever. It even checks for updates when it gets signal again, so nothing is stuck out of date.

There is a visual screen browser that shows all the prototype screens, which makes hopping around a flow painless. Need to jump three screens ahead or backtrack to an earlier state for a quick check? Just click the thumbnail and it swaps instantly. Navigation feels snappy, tapping hit areas is precise, and the whole thing stays out of the way so the prototype is the focus. It is very much a viewer, not a place to edit, and that clarity helps.

Running it on a PC with BlueStacks works well too. Mouse clicks map to taps, scrolling is smooth, and the bigger monitor makes the screen browser extra handy. The redesign trims clutter, labels are clearer, and little UX touches cut down on the “where is that again” moments. Simple, reliable, and ready for quick feedback loops with teammates or clients.

BlueStacks gives you the much-needed freedom to experience your favorite apps on a bigger screen. Get it now.
