Track Your Mood
And Why It Changes

Daylio shows you what mood you were in. tr8ck shows you why — by connecting your mood to sleep quality, nutrition, exercise, hormonal cycle, and GLP-1 medication through AI that finds patterns in your personal data.

Quick Answer

Daylio is best for quick, low-friction mood and micro-habit logging. tr8ck is the better fit if you want mood tracking plus 16 more health modules — sleep, medication, cycle, fasting, nutrition — with AI correlations that show why your mood changes. Free covers 4 modules; Pro is $4.99/mo, Premium $6.99/mo adds AI insights.

WHAT You Feel vs. WHY You Feel It

Knowing your mood was a 3 out of 5 doesn't help you improve it. Knowing it dropped because of poor sleep, a luteal phase transition, and a GLP-1 injection day — that does.

Daylio
WHAT
Logs your mood rating and activity tags. Shows trends over time. Excellent for building the habit of daily mood logging. Can't explain what drove the mood.
tr8ck
WHY
Logs mood and connects it to sleep the night before, exercise, nutrition, hormonal phase, and medication. AI reveals the drivers. You get explanation, not just record-keeping.

Daylio's Strength Is Real

Daylio built a loyal user base for good reasons. Here's where it excels — and what it fundamentally cannot do.

Daylio — What It Does Well
  • Frictionless entry — icon-based mood selection and activity tags take under 20 seconds. This drives consistency.
  • 📈Mood trends over time — clean calendar and chart views showing mood patterns across weeks and months
  • 🎨Simple, beautiful UX — 5M+ downloads earned through genuine design quality
  • 📓Micro-journal format — optional text notes for deeper reflection
Daylio's Fundamental Gap
  • 😴No sleep connection — did poor sleep cause today's low mood? Daylio can't tell you. tr8ck can.
  • 🍽️No nutrition data — Daylio has no food module; no way to see if diet drives mood patterns
  • 💊No medication tracking — for GLP-1 users or anyone on mood-relevant medications, no correlation exists
  • 🔄No cycle correlation — hormonal phases are major mood drivers, especially in the luteal phase; Daylio is blind to this

The Insights That Explain Everything

These are the types of insights tr8ck's AI surfaces after 2–4 weeks of cross-module logging — from your own personal data

Sleep → Mood

"Your mood averages higher on days following 7+ hours of sleep than on days following less than 6 hours. Sleep quality accounts for the largest variance in your mood scores."

Cycle → Mood

"Your mood ratings drop during days 20–26 of your cycle (luteal phase). This pattern has been consistent across your last 3 logged cycles."

Exercise → Mood

"On days when you log 20+ minutes of exercise, your mood score the following day runs higher on average. The effect is strongest after morning workouts in your data."

GLP-1 → Mood

"Your mood ratings on injection days average lower than your baseline. The dip typically resolves within 24–36 hours based on your logged data."

These are illustrative examples. tr8ck surfaces insights based on your own personal logged data — patterns vary by individual.

Why Explanation Beats Recording

You Can't Fix What You Can't Explain

Daylio records that you had a bad day. tr8ck identifies that bad days in your data consistently follow nights with under 6 hours of sleep — and that this pattern is stronger than any other variable in your logged data. Now you know what lever to pull. That's the difference between a journal and an insight engine.

WITHOUT context

"My mood was 3/5 on Tuesday. Logged: worked, watched TV."

WITH context

"Tuesday low mood followed 5.5h sleep, injection day, no exercise. This pattern appears in 7 of your last 8 similar days."

Frequently Asked Questions

Daylio vs. tr8ck

What to consider when choosing a mood tracker

Is tr8ck a good Daylio alternative?

tr8ck and Daylio overlap on mood tracking but serve different purposes. Daylio is an elegant micro-journal — simple, fast, and great for habit-building. tr8ck tracks mood with the same daily consistency, but connects it to sleep, nutrition, exercise, GLP-1 medication, and hormonal cycle through AI. If you want to understand why your mood shifts, not just log that it shifted, tr8ck provides that cross-data analysis. Last updated: April 2026

How does tr8ck track mood compared to Daylio?

Daylio uses icon-based mood ratings and activity tags — typically under 20 seconds per entry. tr8ck's mood module logs a numerical rating, energy level, emotional tags, and optional notes — typically 60–90 seconds. tr8ck takes slightly longer because it captures more context. The trade-off is that each entry becomes part of a cross-variable dataset rather than a standalone log. Last updated: April 2026

Can tr8ck explain why my mood changes?

tr8ck's AI correlates mood ratings with your other health modules. After 2–4 weeks of consistent logging, you'll see insights showing which health variables most strongly correlate with mood variance in your personal data. These are patterns from your own logged history — not generic population statistics. Last updated: April 2026

Does tr8ck track GLP-1 medication effects on mood?

Yes. GLP-1 medications like Ozempic and Wegovy can influence mood via dopamine pathways. tr8ck tracks your GLP-1 dose in the medication module and daily mood in the mood module — AI surfaces whether mood patterns correlate with dose timing or injection days. Last updated: April 2026

Is tr8ck more expensive than Daylio?

tr8ck has a free plan — no credit card required. Daylio's premium is $2.99/month. For a mood tracker that also covers 10 other health modules and AI correlation analysis, tr8ck Pro at $4.99/mo (billed yearly) provides more data value per subscription. Last updated: April 2026
