### 5/5 — This is the best app. Nuff said.

*2026-08-23, version 4.1*

Quite awesome and fully featured. My most used app.

### 5/5 — La meilleure

*2025-01-07*

La meilleure application pour contrôler mon imprimante avec octoprint ! Simple et efficace.

### 5/5 — Beautiful and simple app

*2024-09-21, version 4.0.10*

I’ve tried a lot of octoprint apps and this is my favorite by far. Very easy to use and clearly takes advantage of ios design norms, probably implemented in swift.

### 5/5 — Love Polymer!

*2024-07-27, version 4.0.10*

I’ve been using this app for years for 3D Printing at home, super helpful to control the printer via OctoPrint when you need to quickly access. It’s got a fantastic UI, top work from the developer!

### 5/5 — This is the best app. Nuff said.

*2024-06-03, version 4.0.10*

Quite awesome and fully featured. My most used app.

### 4/5 — Gute App - Aber Cam tut nicht mehr.

*2024-04-15*

An sich gefällt mir die App gut. Habe sie nun ca 3 Jahre genutzt. Allerdings tut die Webcam seit einigen Wochen nicht mehr. In anderen Apps funktioniert diese noch problemlos. Ausserdem dauert es manchmal etwas lange bis die App mit dem Drucker eine Verbindung hergestellt hat.

### 3/5 — Nice app but stopped working

*2024-04-07, version 4.0.10*

Nice app, and worked fine when I was running OctoPrint in a Debian VM, but would refuse to connect when I moved over to a dedicated OctoPi instance

### 3/5 — Beautiful but stale

*2024-03-21, version 4.0.10*

I love this app’s design and simplicity, but its feature set is really lagging behind the free and open-source OctoPod app and plugin. If I could wave my hand and have Polymer support WebRTC streaming (“new stack”), DisplayLayerProgress, Cancel Objects, iOS Live Activities, and push notifications, to name a few, I’d certainly use it over the OctoPod app, which I simply don’t find to be as “nice.”

Any of these on the roadmap?

### 3/5 — Was good, no updates in a year though.

*2024-03-17, version 4.0.10*

No notifications or Live Activities support makes this tough to recommend dropping $10 on.

### 4/5 — Missing one item

*2023-12-17, version 4.0.10*

Does not have an app for Apple TV like OctoPod, which I can check on the printers if I’m watching TV. besides that it works very well with my iPad and iPhone. Thanks.
