Reely vs Motionfly
Motionfly and Reely both turn one prompt into a finished video with no timeline — but they make different things. Motionfly is a web AI tool that generates a launch/App Store video from your screenshots, 3D mockups and AI voiceover, for any platform. Reely drives your real SwiftUI feature in the iOS Simulator and captures a reel of the actual app in motion. Pick Motionfly for a narrated, cross-platform launch trailer; pick Reely when the demo has to be your real, running iOS app.

| Pricing | Pay once ($89–$129) | Free to start; paid credits / subscription |
Real app footage vs generated motion
This is the whole difference. Motionfly never runs your app — it assembles a polished video around the screenshots and 3D mockups you give it, animates them, and lays an AI voiceover on top. Reely does the opposite: it builds an iOS harness, launches your real SwiftUI feature in the Simulator, and drives the actual navigation and state inside `withAnimation` so genuine native transitions play. The reel is your real UI in motion, not an animated approximation of it.
Two kinds of “one prompt → video”
Both tools skip the timeline and keyframes, and both start from a prompt — so on the surface they look similar. But the artifact is different. Motionfly produces a launch/explainer trailer: narrated, music-backed, mockup-driven, and platform-agnostic, great for a Product Hunt or App Store splash. Reely produces a product demo reel: the real feature, auto-zoomed toward each interaction, dead air cut, captioned. One sells the idea with synthesized polish; the other shows the thing actually working.
Why a real running app matters for iOS
Mockup animation can’t show a gesture resolving, a sheet presenting with the system spring, or the exact spacing of your shipped UI — it shows a stylized stand-in. For an evaluator or an App Store viewer judging a native app, that fidelity is the point. And because Reely captures from the live build, when your UI changes you just re-run it and get a fresh, accurate reel — no re-prompting to match the new screens.
Pay once vs free-to-start credits
Motionfly is free to start and then moves to paid credit/subscription plans as you generate more. Reely is a single purchase ($89 Solo, $129 Studio) with lifetime updates. If you produce iOS demos regularly, paying once is usually cheaper than buying generation credits over time.

Which one should you use?
Choose Reely if…
- The demo has to show your real, running iOS app
- You want native gestures, transitions and exact UI fidelity
- You’re demoing a native iOS / SwiftUI feature
- You’d rather pay once than buy credits or subscribe
- Your AI agent already builds the feature — let it make the demo
Choose Motionfly if…
- You want a narrated, voiceover-driven launch or explainer video
- You’re covering multiple platforms (iOS, Android, web, SaaS)
- You’re happy with screenshots + 3D mockups instead of live capture
- You want a slick App Store trailer fast, without a running build
- You don’t have — or don’t want to capture — the real app
FAQ
They overlap — both turn a prompt into a finished video with no timeline — but they make different things. Motionfly generates an AI launch video from screenshots, 3D mockups and voiceover; Reely captures your real running iOS app. Choose by which artifact you need.
No. It builds an animated video around screenshots and 3D mockups with AI voiceover. Reely drives your actual SwiftUI feature in the iOS Simulator, so the reel shows the real UI in motion.
If you want a narrated, cross-platform launch trailer, Motionfly. If the preview should show your real iOS app’s real interactions, Reely. Some teams use Motionfly for a launch trailer and Reely for the in-app demo.
Reely is a one-time purchase ($89–$129) with lifetime updates. Motionfly is free to start with paid credits/subscription beyond that, so the cheaper option depends on how many videos you make.
Let your agent make the reel.
Reely turns your iOS feature into a clean, auto-zoomed, captioned sizzle reel — no recording, no editing, no Simulator wrangling. Pay once.
