## What is mo?

Still building formations only in your head?

mo-sim is a formation design app for choreographers. It lets you simulate dancer movements and stage formations in sync with music — so the picture in your head becomes a moving picture on your screen. Play the song, and dancers actually move on the canvas.

Whether you're working alone, sharing with your team, or finalizing before showtime — mo-sim helps you show what words can't describe.

-----

[Start free. Unlock more, once and for all.]

mo-sim's core features are all free to use. No account needed — just download and start designing. When you're ready to unlock advanced features, there's no monthly subscription. A single one-time purchase, and they're yours forever.

[Craft every detail, right in your hand]

Set each dancer's entry timing, stop points, movement path, and facing direction. Zoom out to see the whole stage, or zoom in on a single dancer. Batch-edit multiple dancers and scenes at once, cutting down hours of work that paper or PowerPoint would demand.

[Compare ideas side by side]

Not sure which version works best? Create multiple formation drafts in parallel and compare them on the spot (Parallel Scenes). Attach reference videos, rehearsal footage, and notes directly to each scene — keep your entire creative process in one place. Save your go-to stage layouts and team rosters as presets, so you can start your next piece in seconds.

[Built for every kind of stage]

From professional choreography sessions to school dance clubs, theater rehearsals, and group performances of every kind. Replace your paper notebooks with a digital canvas, free up time to focus on what matters — the ideas — and cut down on rehearsal time and studio costs.

[Bring out your best creative work with mo-sim]

Every choreographer has been there: the vision is clear in your head, but words and gestures aren't enough to share it. mo-sim was built to lower that wall — so you can spend less time explaining movement, and more time creating it.

### 2/5 — Too confusing

*2020-02-20*

Although I love the concept of this app and have been looking for something like this for a long time, I wasn’t very satisfied with the results. The app is really confusing, and some of the buttons are in Japanese even when the selected language is English. Also, I can’t figure out how to get any of my “people” to move at the right time. I’ve tried literally every button. While the idea is great, this app wasn’t very well thought out.

**Developer response:** already open English ver!

### 4/5 — English plz

*2020-02-04*

I like this app, but it’s not in English, so it makes it harder to use

**Developer response:** Operation in English is now possible!

### 2/5 — No english

*2019-10-13*

Could be nice but it is not in English so can’t use it

**Developer response:** Operation in English is now possible!

### 2/5 — Good idea but

*2019-09-11*

Seems like a good app, but it’s all in Japanese with no option for any other languages. It makes it very hard to use.

**Developer response:** Operation in English is now possible!

## Version history (last 5 releases)

### 1.7.8 — 2026-06-14

Fixed an issue where audio or video playing in other apps (such as YouTube background playback or Picture in Picture) would stop when you used this app. You can now check your moves and formations comfortably while playing music or video in another app. Thank you for using mo-sim!

### 1.7.0 — 2026-05-23

Thank you for using mo-sim.

[New Feature: Bulk Scene Deletion]
Long-pressing a scene and tapping the delete button now enters checkbox mode. You can select multiple scenes and delete them all at once.

[New Feature: Bulk Parallel Scene Deletion]
When a scene has multiple parallel variants, you can now select which ones to delete from the management menu and remove them all at once.

[New Feature: Lock Parallel Scene]
A new "Lock" option has been added to the parallel scene management menu. When locked, tapping the scene will no longer cycle through parallel variants. A lock icon appears on the cell to indicate the locked state.

[New Feature: Chapter Function]
You can now group consecutive scenes into a single chapter. Grouped chapters are displayed as a hexagonal cell and can be collapsed or expanded with a tap. This makes it easier to organize long formations. Chapters can be dissolved at any time.

### 1.6.8 — 2026-05-17

Thank you for using mo-sim.

[Improvement: Display Position Preserved During Screen Rotation]
When switching between portrait and landscape, the area you were viewing now stays centered on screen. Previously, the view position could shift after rotating — now it transitions smoothly at any zoom level.

[New Feature: Close the Track Panel with × Button]
A × button has been added to the track settings panel that appears when you tap the movement button. Tap it to instantly close the panel.

[New Feature: Choose Grid Movement Units]
Tapping the grid button now opens a panel where you can select the movement unit for dancers: 0.5, 0.25, 0.125, or Free. The default is 0.25. This makes fine-tuning formations more flexible than ever.

### 1.6.4 — 2026-05-12

Thank you for using mo-sim.

[New Feature: Playback Speed]
You can now change the playback speed in 9 steps: x2.0 / x1.5 / x1.0 / x0.985 / x0.9 / x0.8 / x0.7 / x0.6 / x0.5. Audio, video, and dancer movements all change speed together, while pitch is preserved.

Tap the speed button near the waveform to open the speed panel. Changes take effect immediately even during playback.

[Improvement: Track Button UI]
When the track settings panel is open, the move button is now highlighted with a border to indicate it can be tapped again to close the panel. Also fixed an issue where the move button label would appear dimmed when tracks were set to OFF.

[Bug Fix]
Fixed an issue where dancers would jump instantly when switching scenes in track range mode instead of animating smoothly.

### 1.4.9 — 2024-10-29
