### 1/5 — Captioning and Translation not working on even g2 realities mentraOS 3.0

*2026-08-18*

MentraOS 2.0 or whatever the previous update was worked quite well; the transcription of my target language was good, and punctuation and diarisation was relatively high quality. The translation function lacked translation for my target language, but I expected that to be fixed with MentraOS3.0.

However, mentraOS3.0 with my Even realities g2 is not working at all. Neither transcription nor translation appear to be even connecting properly. Specifically, the translation and transcription text is not showing up in the miniapp nor the glasses UI. Instead it keeps saying connection lost.

### 3/5 — Seems really great, waiting for G2

*2026-04-19*

Good but can improve

### 1/5 — iOS on boarding issues

*2026-04-15*

there is no way for me to use the product out of the box because the pairing set up. I see everything connected to via Bluetooth and then within the app it says open settings to pair and wait till it is connected. I do that but nothing updates on the app there's no other button to press other than open the settings again it's very frustrating. I look forward to hearing back from the Dev team. I will be following up with a GitHub issue.

### 1/5 — Garbage app (for now)

*2026-02-10*

It could be a lot better than the first party garbage. But this is all we got as early adopters.

### 5/5 — Great for translations

*2026-01-24, version 2.2.15*

I moved to my wife’s native country without knowing the local language. I got a pair of Even Realities G1, and I was very disappointed with the software experience on it. The translations never worked great. With MentraOS I was able to follow the conventions that were happing when we visited my wife’s relatives. Only time I had issues was with poor internet connectivity, but not much MentraOS can do about that.

### 5/5 — Much quicker startup

*2026-01-14*

The biggest hurdle with the standard G1 software is the number of steps to go through before captioning will happen. With the Mentra, you just start te app, wait few seconds for the initial connection and ready to caption. Awesome! And it captions multiple languages at the same time. I speak both Dutch and English and you can just mix it up and voilá.

### 5/5 — Best Smart Glasses App

*2026-01-14*

Best smart-glasses app I’ve used so far. Clean and fast.

### 5/5 — Great SDK

*2026-01-10*

I used the Mentra SDK to build apps for smart glasses. It's really very seamless and intuitive.

### 5/5 — Happy for an open source option

*2026-01-08*

There’s still some bugs, but it’s early for this team. Excited that they’re keeping the entire operating system open source. Keep up the good work!

### 4/5 — Runs smooth

*2026-01-06*

Mentra runs smoother than the Even Realities OS. It can get slow if you're running too many of their miniapps at the same time. though
