Ratings and reviews

I haven't actually tried it yet, but I downloaded it, and it's like downloading two gigabytes of data, which is probably all of the information that it uses. It should be more than efficient on a modern device, especially with an NPU and a high-powered processor. All the negative reviews are probably from people who don't have the most recent phones, phones that don't have NPUs. On the S25 Plus, with a 4.5 GHz processor, a GPU, and an NPU, replay started 1 -1.5 seconds VERY FAST!! SLOW

Not sure why this app has so few downloads and reviews so far, but it's one of the best offline ai's I've used. It runs smooth as butter on my device. It has so many options, features, and models to choose from. Upgrading to premium is optional, the app still works great without it. The upgrade is a one time purchase and pretty cheap at around $12 USD. The features you get from premium are more than worth it I'd say.

Pretty fast and good once you get used to it. I have paid for the pro version, which adds customisation prompts. I would however like a way to export chats, and a dedicated memory area where you can save specific information for referencing by the model.
