v0.5.0 - Welcome aboard

This version is all about first impressions and daily habits.

Added an onboarding flow for new users - a quick walkthrough that explains the basics and lets you configure your timer preferences right away. First-time experience matters, even for a timer app.

Daily goal tracking is the other big addition. You can set a target number of Pomodoros per day and the app tracks your progress. It’s simple, but seeing that progress bar fill up is surprisingly motivating.

I also reorganized the settings page - it was getting a bit crowded after all the features from v0.3.0. And fixed a bug where toasts weren’t auto-dismissing properly.
