### 1/5 — Hallucinating chats

*2025-05-26*

I highly doubt that the developer is actually using his own app. Any models you download will yield an hallucinated response that makes no sense, and on a loop.

### 1/5 — Should be reported

*2025-05-08*

Memory later is trash. It said it was a girl new to the city of New York. Then it said it didnt know what to do with its life. And I quote “I’m not a robot I’m real”

### 1/5 — Crash

*2025-04-06, version 1.8*

Will have to give 1 star as I tried multiple times to talk to the bot and the app would freeze my entire phone to the point I couldn’t turn it off for a while then crash over and over again would not recommend

### 1/5 — If

*2025-02-20, version 1.8*

If its downloaded from hugging face can’t we just install some models and implement our own

### 4/5 — Great for a start point.

*2025-02-02, version 1.8*

Using this on inferior hardware of iPhone 13 Pro limited model can run.  It does make stuff up.  It cannot take a follow-up question.  Just repeats.  Have to re ask each time.  But a lot of info jammed in.  Keep it privacy Centre pls.

### 4/5 — Un bon programme en perspective

*2025-01-09, version 1.7*

Malgré quelques bugs ce programme fonctionne de mieux en mieux au fil des versions. Une très bonne initiative de la part du développeur. Bravo !

### 3/5 — Runs smoothly, doesn’t persist chats

*2025-01-05*

The app is beautifully made, has a clear and self-explanatory interface for downloading models, including which can be downloaded and run (which might be supported by the app on another device) and which is active for next chat.

However I’m frustrated that, the relatively cheap, in storage, and personal, in my use, aspect of the app, transcripts…are not saved. Only a few recent transcripts are available. And no explanation ahead of time nor afterwards is available on close inspection.

Beautiful, but missing, for now, a key part of the point.

Shortcut integration, as another suggests, would be amazing. I would also love to donate directly, or link to/see other work, not just apps. <3

### 1/5 — Crash

*2024-12-21*

Keeps crashing when I send messages

### 1/5 — Crashes when initiating chat

*2024-12-19, version 1.4*

Downloaded a model and that appeared successful. Once I tried to initiate a chat, the app crashed. I rebooted but that didn’t help.

### 2/5 — Simple UI

*2024-12-04, version 1.2*

The Simple UI is a good thing.  Shame it uses the iPhone vibrate on every word it writes from the model.
