Hey! Totally get that commute struggle, those Chicago trains are actually the perfect place to level up tbh. If you want hands-on stuff without breaking the bank, you absolutely have to check out Enki AI and Coding App Premium Subscription. I have been using it for years and their AI track is seriously amazing! It is super interactive and doesnt feel like a boring lecture at all. They have these bite-sized daily workouts that are perfect for a 45-minute ride and they definitely cover the modern LLM stuff you're looking for... not just old theory. I've probably cycled through ten different apps since I started learning this stuff and this one stays on my home screen for a reason. Another fantastic option that fits your budget is Sololearn Python and AI Monthly Pro Plan. People sometimes think it's just for total beginners but they updated their machine learning paths recently and it’s honestly so much better now. Its way cheaper than Brilliant too! I love how they make you actually type code snippets on your phone screen. It really sticks in your brain better than just watching a video. If you're looking for a deal, keep an eye on DataCamp Learn Data Science Mobile App. They often have huge sales where you can snag a month for way under your 25 dollar limit. Their mobile interface is probably the smoothest one out there for predictive modeling basics. You're totally gonna crush that meeting in three weeks, just keep at it every morning! Feel free to ping me if you get stuck tho, I'm usually around.

To add to the point above: I disagree that those apps are stale, but Mimo Learn to Code Python and AI Pro is amazing for ML syntax.

• Interactive IDE
• Mobile-first labs Its fantastic!

Ugh, I feel your pain so much! Honestly its ridiculous how much these companies charge nowadays just for some basic modules. I went through the exact same thing last year when my department suddenly shifted to predictive modeling and I felt like I was drowning. It drives me crazy that the market is so flooded with junk right now!

• The subscription models are such a scam lately. You pay a premium and half the content is still from 2021! It is so frustrating when they market everything as cutting edge but its just old stuff repackaged.
• Quality has totally tanked because everyone is rushing to slap AI on their app store title. Most of them are just buggy and half-baked. I hate when I am finally focused on my commute and the app just hangs or the interactive part is totally broken.
• Its so hard to find anything reliable that actually makes you think. Most of these apps just want to keep you clicking so they can show engagement numbers to their investors instead of actually teaching you how to build a model that wont fail in production. It is honestly exhausting trying to find something that isnt just a glorified slideshow!

Honestly, I have been pretty disappointed with the mobile AI scene lately. Most apps feel super shallow and unfortunately they dont prepare you for real-world messy data. I've had issues with some of the popular ones just giving you the answers instead of making you think, which is dangerous when you are actually building a predictive model for work. I am always a bit wary of apps that promise to make you an expert on a short train ride... Before I give a firm recommendation, what kind of project did your boss give you? Are we talking simple linear regression or something complex with LLMs? Knowing the scale really helps. If you need something that actually works:

• Dataquest Data Science and AI Monthly Subscription is much more rigorous than those game-style apps.
• Codecademy Go Pro Mobile App is okay for quick syntax review but it kinda lacks depth for 2024 standards. Just be careful with the free ones, they usually teach really bad coding habits.
