You're designing an app. Open it in Prototo and see it the way it was meant to be seen on your phone, in full fidelity. Prototo is a viewer for native prototypes. Tap a link and the design opens full-screen on your device, with the detail that flat mockups and screen recordings can never capture: ⢠Real Liquid Glass: genuine system materials, not screenshots faking the look ⢠Real gestures: swipe, scroll, drag, and tap with true native response ⢠Real haptics: feel every tap and transition the way people actually will ⢠Real navigation: native nav bars, sheets, and transitions FOR STAKEHOLDERS, REVIEWERS & CLIENTS Stop reviewing designs as static images or laggy videos. You hold the actual feel of the product in your hand, how it moves, how it responds, how it sounds. You'll give sharper feedback because you're experiencing the real thing, not imagining it from a picture. FOR DESIGNERS Preview your own work on-device as you go. See exactly how your prototype behaves with real materials, real motion before anyone else does so every reviewer sees the same high-fidelity preview. No builds to distribute, no TestFlight invites to chase. WHY PROTOTO Design tools render an approximation of native apps. Prototo displays the real thing, using the same native interface components your shipping app will. What you preview is what your users will feel.

Verdict
The clearest difference is update cadence: Prototo at every 3 days against RatePilot's every 6 weeks. RatePilot's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
