## Most critical reviews (10 lowest-rated)

### 1/5 — Inhalt nicht derselbe wie in der Beschreibung

*2026-03-13*

Leider ist in der Vorschau im App Store mehr vorhanden als in der heruntergeladenen App. Es fehlen die gelben und blauen Zielpunkte. Das war jedoch der Grund warum ich mich für diese App entschieden habe. Schade…

### 1/5 — Not smooth

*2025-10-10*

The flow is not smooth at all very jerky like it is glitching. This does not function as it should. The metronome doesn’t work. I can’t change the direction of flow. I’d like a refund

### 1/5 — Glitches

*2024-11-13*

It would be so great but it glitches, causing it to not be a smooth transition of the lines, which feels like it isn’t helping with the vertigo like it should because my brain is trying to figure out the glitching.

### 1/5 — schade

*2024-10-13*

leider läuft die gekaufte app version nicht auf meinem macbook air, wie angegeben

### 2/5 — Disappointed

*2026-06-11*

Purchased the in app purchase for the metronome sound and it doesn’t work. My sound and ringer was all the way up, my phone was not on silent and still not working.

### 2/5 — Upside down dogs

*2026-01-08*

I really was liking this app for clinic to hold kids attention. But now the animals scroll upside down no mater what orientation I hold my iPad. I tried unlocking and locking the screen orientation but it did not fix the issue. Frustrating. I wish the developer would fix this glitch.

### 2/5 — Not all features are here mentioned

*2024-05-11*

The video shows a dot for gaze stabilisation, but this app doesn't have that feature.

### 4/5 — Just the ticket for MddS

*2024-01-03*

Just what I was looking for to try and combat my MddS.
BUT - could an option please be added to change the stripe direction? And to have the app be full screen in landscape mode for my iPad?

**Developer response:** Thank you for the feedback. To change the direction of the stripes you just have to rotate your device. The orientation should be locked to make this convenient for you. Please email me at mullman@gmail.com if this doesn’t work for you. I will try to incorporate a fix for you!

### 5/5 — Great rehab tool

*2025-12-06*

This is fantastic as a tool for vestibular rehab! Is there a way to make it a 360 immersive video version—where it looks like you are in an optokinetic drum (compatible with a phone VR headset) to use for patients with MdDs?

### 5/5 — Awesome!

*2023-12-13*

My favorite OKN drum app! Great fixation target feature.
