iOS demo video comparison

Reely vs MotionflyShow the real app — not an AI approximation.

Motionfly builds a launch video from uploaded assets and generated motion. Reely drives registered SwiftUI actions so the screens and native transitions come from the running build.

Mac app · Agent skill · No recording session

The straight answer

Start with the job, not the feature list.

Motionfly and Reely both turn an agent request into a finished video without requiring a timeline, but they create different artifacts. Motionfly generates a cross-platform launch or explainer video from your prompt and uploaded screenshots or screen recordings, adding 3D mockups, animated text, AI voiceover, music, and sound effects. Reely drives a registered SwiftUI feature in the Simulator and captures the real app state and native transitions. Pick Motionfly for a narrated launch trailer; pick Reely when the story must be repeatable footage of the running iOS build.

Where the workflows really split.

The practical differences you will feel every time you need a new demo.

01

Real app footage vs generated motion

This is the central difference. Motionfly does not drive a live app flow; it assembles a polished video from your prompt and uploaded screenshots or screen recordings, then adds mockups, animation, and narration. Reely builds an iOS harness, launches the SwiftUI feature in the Simulator, and drives registered navigation and state actions so genuine native transitions play. The resulting footage is tied to the current build rather than reconstructed from supplied assets.

02

Two kinds of “one prompt → video”

Both tools can produce a first cut without requiring a timeline or hand-authored keyframes, so on the surface they look similar. But the artifact is different. Motionfly produces a launch or explainer trailer: narrated, music-backed, mockup-driven, and platform-agnostic. Reely produces a product demo reel from the running feature, auto-zoomed toward each interaction, with dead air cut and authored callouts timed to the flow.

03

Why a real running app matters for iOS

Generated mockup motion cannot reproduce every state change, sheet presentation, or spacing detail from the shipped build unless those moments are supplied as assets. Reely records them from the running feature. When the UI changes, the agent can re-run the same Flow Spec and recapture the current screens, interaction geometry, and timing marks before rebuilding the edit.

04

Published pricing vs a free starting point

Motionfly says you can create a first video free without a credit card, but it does not publish paid tiers, generation limits, or renewal terms on its public marketing site. Reely publishes one complete plan at $9.99 monthly or $89.99 annually. Until Motionfly publishes or presents paid terms in its product, a reliable long-term price comparison is not possible.

Choose for the job you actually have.

Reely

Choose the generated workflow if…

  • The demo has to show your real, running iOS app
  • You want real SwiftUI state, transitions, and exact UI fidelity
  • You’re demoing a native iOS / SwiftUI feature
  • You prefer predictable, publicly documented pricing
  • Your AI agent already builds the feature — let it make the demo
Motionfly

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 to build from uploaded screenshots or screen recordings
  • You want a slick mobile launch trailer without a running build
  • You do not want an agent to drive the real app

Pricing, without the fog.

Reely

Every feature. One plan.

$9.99/month or $89.99/year. One plan with every feature included.

Motionfly

Their pricing

Free to start with no credit card. Paid prices, generation limits, and subscription or credit terms are not published on the public site.

Motionfly markets dedicated App Store Preview workflows, but store acceptance still depends on Apple’s current content and technical requirements.

Questions, answered.

They overlap because both can turn a prompt into a finished first cut without requiring a timeline. Motionfly generates a launch video from uploaded screenshots or recordings, mockups, animation, and voiceover; Reely captures a repeatable flow in the running iOS build. Choose by which artifact you need.

Motionfly’s web workflow can use uploaded screen recordings, but it does not drive a live app flow. Its separate desktop recorder is currently advertised as coming soon. Reely drives registered SwiftUI actions in the Simulator and captures the result from the running build.

Choose Motionfly for a narrated, cross-platform launch or explainer video built from supplied assets. Choose Reely when the central proof should be a repeatable recording of the real iOS feature. App Store submission requires a separate check against Apple’s current preview rules.

Reely publishes $9.99/month or $89.99/year with every feature included. Motionfly is free to start, but its public site does not disclose paid prices or limits, so a reliable ongoing-cost comparison is not currently possible.
