I built a fast mood, energy, and activity tracker (trilog.app)
Fast mood tracker with week grid, but local journaling apps already saturate iOS.

Simple local-first mood tracker when Daylio and Stoic already dominate the category.

I built MoodPulse App, a small app that helps you log your mood in seconds and visualize how it changes over time.
The idea came from wanting something simpler than most journaling or mental-health apps. Many of them require long entries or feel heavy to maintain daily. I wanted something that takes just a few seconds but still gives useful insights.
What it does:
• Log your mood with a single tap (with optional notes) • Visualize emotional trends with simple charts • Track streaks and weekly patterns • Share visual mood charts with friends if you want
The focus is on speed and consistency — something you’ll actually keep using.
I’d really appreciate feedback from the HN community, especially on:
• whether mood tracking like this is actually useful • features that would make it more valuable • privacy expectations for apps in this space

GitHub-style contribution grid for screen time, but Apple Screen Time already tracks this.
Clean HealthKit viewer focusing on streaks and calendar heatmaps without subscription clutter.
Skype, Google Voice, and Dingtone already do this; Voklit adds nothing novel.
Correlates mood against Screen Time and HealthKit data automatically on device.
