### 4/5 — Cool-ish App

*2025-04-08*

The app is neat, however it drains battery in the background like crazy because of the model loaded in the RAM. Also the lack of having and storing multiple chats, inability to upload files and images, not having an option to drop in a Google API key or use DDG search makes it kinda lame. Neat idea though.

### 5/5 — Good app, but not working on ipad m4

*2025-04-06*

My platform is an iPad M4(2024),the model never output anything. My ipad is becoming a bit hot, so there must be something going on, but the ui or something is broken I guess...

### 2/5 — Problem Google captcha

*2025-04-06, version 1.1*

Ist bestimmt eine nette Alternative, aber was soll das mit dem unnötigen Google captcha um es im playground nutzen zu können? Das funktioniert zum Beispiel nicht bei mir, vielleicht weil ich ein Pihole als Sicherheit in meinem Netzwerk habe?
Bei mir kann und möchte ich keine Google Services nutzen lassen, hier wird definitiv Datenklau betrieben. Schade, deinstalliert und beim ersten Test/Versuch durchgefallen.

### 3/5 — C’est cool

*2025-03-19, version 1.1*

Je trouve que c’est presque bien, il n’y a pas la prise en charge du français car quand on commence un prompt en Français il me met trois petits points, que quand je commence en anglais puis Français ça me répond en français, puis peut faire crash l’iPhone du à la taille du modèle, testé sur 15 pro max

### 4/5 — Fonctionne partiellement

*2025-03-09, version 1.1*

Application qui fonctionne partiellement car elle redirige sur un site server pour discuter avec une AI en se justifiant que l'espace n'est disponible pour le modele local qui pèse 8Gb. 
L'AI sur le site fonctionne mais autant utilisé safari directement. 
Merci au développeur car je connaissais pas ce modèle.

### 4/5 — Amazing, but I would love RAG

*2025-03-02, version 1.1*

This app is sleek and visually impressive. Leveraging a top-notch model with both MoE architecture and meticulous training, the performance is outstanding. However, incorporating features like Retrieval-Augmented Generation (RAG), multiple system prompts for versatile personas, and seamless integration with Apple Shortcuts would elevate it to an essential tool for every iPhone user.

### 5/5 — This app is surprisingly good

*2025-02-26*

I use it for everyday general knowledge questions as well as a “customer support” resource when I have questions related to a product.

### 5/5 — LLM not working

*2025-02-11*

I get to the download screen, put my phone away, and when I open it the chat pops up. I try to text it something, but all I get back is “…”. Not sure if I am alone in this. I am rooting for this app! Please fix if possible.

### 5/5 — A solid AI for offline use

*2025-02-11*

This AI will answer any question you can throw at it, even completely offline. Would be super useful in a survival or disaster situation where Internet service is out.
