Status: MVP Finished ✅

Why

• when I work out, I normally keep my plan and progress in a personal discord server or a simple text file.
• but that makes the logs hard to read/track
• I also use a metronome from google by literally googling "metronome" and using the google provided metronome
• I also don't really keep track of the rest times
• so to solve all of that, I made this
• it's a simple desktop app that keep track of my workouts, workout logs, rest times and metronome

Goals of this project

• make something that I want to use ✅
• actually finish a project and not abandon it ✅
  • by aggressively cut down on scope and complexity
• learn intuition behind client side development (it's all about state management!) ✅
• use LLMs extensively during development to get more practice using LLMs ✅
• learn about egui, sqlx ✅

Next Steps

• actually use the app and see where it's needs improvement
• statistics?
• something for the home page?

AI usage note

• so I wrote this project with AI writing about 70~80% of the code

Some insights from using AI

• AI is very good at basic simple stuff (forms, pagination for client side development and SQL for "backend" development) and this project was a good showcase of that
• AI is terrible at writing good abstractions so if you let it go wild, you write a bunch of slop
• if you poke it and prod it right, AI can make you super fast. Without AI, this would have taken me several weeks even months from trial and error

Models used

• Gemini 3.1 Pro (around 95% of the time)
• Claud 4.5 Opus (5% of the time when Gemini randomly failed)

AI integration tool

• Jetbrains official AI plugin with the AI Ultimate plan
  • IDE: IntelliJ IDEA with Rust support

Techniques used for AI code generation

• coming up with a high-level plan
• splitting up the plan into small tasks (just in my head)
• defining method/function signatures and scaffolding for the AI
• directing AI towards samples of code it can reference that was of good enough quality that can be reused
• aggressively starting new chats for every task and not using long-running conversations
