Reely vs RocketSim
RocketSim is a Swiss-army companion for the iOS Simulator: it records App Store-ready clips with device bezels and touch indicators, and adds network inspection, design comparison, deep-link testing and more — but you record and polish each clip yourself. Reely does one thing: your agent drives the feature and outputs a finished, auto-zoomed, captioned reel. Pick RocketSim for everyday recording plus debugging breadth; pick Reely when you want the marketing reel made for you.
Reely vs RocketSim, at a glance
| Feature | Reely | RocketSim |
|---|---|---|
| What you get | Finished auto-zoomed, captioned reel | Bezel / touch-indicator recording you assemble |
| How it’s made | Agent drives the feature from a spec | You drive the Simulator and record |
| Auto-zoom | Automatic, toward each step | Not automatic (manual framing) |
| Captions | Auto-authored from your flow | Manual |
| Touch indicators | Rendered from real driven interactions | Yes (a RocketSim strength) |
| Debugging tools | No — reels only | Yes — network, deep links, design diff, etc. |
| Brand theming | Theme-from-app | Manual backgrounds & bezels |
| Agent / CLI | Built around MCP + CLI from day one | CLI + agent skill (recently added) |
| Pricing | Pay once ($89–$129) | Subscription (~$99/yr range) |
A workshop vs a single sharp tool
RocketSim is a tool you keep open all day: record clips, inspect network traffic, test deep links, compare designs pixel-for-pixel. That breadth is its strength. Reely is deliberately narrow — it makes the demo reel and nothing else, but it makes it end-to-end with no manual steps. They’re not really substitutes so much as different jobs; many teams would happily run both.
Recording vs authoring
With RocketSim you still perform the flow and frame each shot. Reely authors the reel from a declarative Flow Spec: it drives the SwiftUI feature inside `withAnimation` so real native transitions play, captures pre-action rects, and auto-zooms toward each interaction. You get the cuts, zooms, and captions without recording a take.
Both speak “agent” now — but differently
RocketSim added a CLI and an agent skill, which is great for scripting captures. Reely was designed spec-first from the start: the run_reel MCP tool is the primary interface, so the same agent that wrote your feature can produce the reel in the same conversation. The difference is RocketSim automates recording; Reely automates the whole reel.

- You need network, deep-link, or design debugging
- You’re happy to record and frame clips yourself
- You want manual control over each recording
FAQ
For making demo/marketing reels, yes. Reely generates the finished reel automatically. RocketSim is a broader Simulator companion (recording plus debugging) where you drive and edit captures yourself.
Reely renders interactions from the real driven flow, so taps and gestures are visible in context. RocketSim’s touch indicators are a manual recording feature.
RocketSim’s skill automates recording; Reely automates the whole reel — driving the feature, auto-zoom, cuts, and captions — from one prompt. Different scope.
Absolutely. Many teams keep RocketSim for day-to-day inspection and use Reely specifically to produce polished demo reels.
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.
