GPT question, if anyone has experience that could help…

So I’ve been using ChatGPT 3.5 for a little while now in helping me brainstorm a sci-fi story I’m working on. Overall, I love it and it’s been amazingly helpful. But…and this “but” is bigger than my ex-wife’s…it’s has two major issues. First, it has no memory, so any tweaking of previous ideas have to be fully explained to it [i]again[/i], and considering we’ve working out species evolution and traits across serval worlds, starship drive types, weapons characteristics, defensive measures, and several other details, that’s [i]a lot[/i] to have to re-explain to it. Second, it gets “confused” a lot with math related issues. For example, yesterday I was working out water properties for a world with 33% more gravity and an atmospheric pressure at sea level of 17psi, and then asked several follow up questions. It could never keep straight if the freezing point of water was positive or negative 20 degrees C in those conditions. Likewise it was never sure if Helium4 and Hydrogen4 were the same thing or completely different when talking about the interior of a star.

So, does anyone know of an iPhone app for GPT that’s is better with math and science and has a memory for previous conversations? Free would be nice, but a reasonable subscription fee would be worth it. I’m looking at Genius with its $15 a month fee.

Oh, and vocal interface is almost a must…having a conversation is so much easier than typing it all out.

You know you can make ChatGPT remember stuff by configuring custom instructions right? It's accessible by clicking your username in the drawer tab to the left, and then choosing settings (or maybe custom instructions is separate). Then you can type in what you want the bot to remember and what to respond with; this only works for new chats so your current chat won't be updated.

Sadly though, LLMs aren't that great with math as they primarily trained on text. Even if you paid for ChatGPT Plus or used a free alternative like Co-Pilot (formerly known as Bing AI), you'd still be at a disadvantage. I'm not sure of any apps on Android nor iOS that can have a LLM that's proficient with math sorry. Oh right...I don't know if custom instructions are even a thing for the mobile app, but it's available on the website.
