happiness tracker
built for noticing.

A two-minute evening check-in that captures your daily energy, the activities behind it, and four mindful lenses on why the day felt the way it did. Over a few weeks, the patterns become a map for designing more happy into your life on purpose.

The basics

What is a happiness tracker?

A happiness tracker is a small daily ritual. You log how the day landed, capture what made it that way, and let the patterns surface over time. The good ones aren’t asking you to summarize your mood with a single emoji. They’re capturing four small things (energy, activities, why, and how each one felt) in under two minutes.

Lantern is the happiness tracker designed for the day you’re actually having. No streaks. No badges. No advertising-driven nudges. Just a quiet evening check-in, and after about two weeks, a patterns view that reveals what really fuels you, and what really drains you.

How it works

How the happiness tracker works.

Four small steps every evening. The first time takes two minutes. After that it’s faster.

01

Set today’s energy.

One slider, 1 to 10. The lantern dims or brightens with you. That single number is the spine of every pattern Lantern will eventually surface.

NOTE

First quiet morning all week. Sun came up over the bridge.

02

Log what made the day.

Add the activities that mattered, mark each as a giver or drainer, then tag four mindful lenses (Who, Where, What, Things) so the tracker can later see what really moved you.

Watch the patterns emerge.

After about two weeks, your tracker has enough data to surface the patterns: top givers, top drainers, your best day of the week, the cues that actually predict a great one.

The fields

What a good happiness tracker actually records.

Four small fields, captured in the moment, in under a minute. That’s the recipe.

01

Energy

A 1–10 sense of how alive the day left you. Plus a −3 to +3 score per activity that moved it.

02

Activity

What you actually did. Autocompletes from your past, so re-logging the recurring stuff takes one tap.

03

Lenses

Who, Where, What, Things. Four mindful angles on why the day felt the way it did.

04

A one-line why

The sentence you’ll thank yourself for noting. Specifics live here, not in tag taxonomies.

The patterns view

The happiness tracker that talks back.

After two weeks, Lantern starts surfacing patterns automatically. Not because you asked it to, but because they were always there in your data.

  • 30-day heatmap Each day a square. Warmth maps to energy.
  • Top givers and drainers Ranked by average impact across all your logs.
  • Day-of-week shape Saturday isn’t actually everyone’s best day. Find yours.
  • Pattern cards “Mornings with a run land +2.4 higher than days without.”
  • Cues, not nudges A quiet suggestion when the data is strong enough. Never push.

Different on purpose

Why Lantern is a different happiness tracker.

Most wellbeing apps are built for the wellbeing app’s metric. Streaks, opens, daily nudges. Lantern is built for one thing: helping you see your own life more clearly.

FAQ

Common questions about a daily happiness tracker.

Is Lantern a mood tracker or a happiness tracker?

Both, but the framing matters. Mood trackers tend to ask "how did you feel today?" which is useful but lossy. A happiness tracker, in our sense, captures the activities and lenses behind the feeling, so the patterns can tell you which parts of your life are actually fueling you.

How long does the daily check-in take?

About two minutes for a full entry: energy, four lenses, a one-line why. Re-logging an activity you already have on file takes seconds because the field autocompletes from your past.

How is this different from journaling?

A journal is a story. A happiness tracker is a dataset. Lantern is built to give you both: the small note for the narrative, the structured fields so the patterns can surface over time.

When will I actually see patterns?

Around day 10 to 14 of regular logging. Some patterns surface earlier if they’re strong (a recurring activity that always boosts or drains you). Real day-of-week and time-of-day signal needs about a month.

Do I have to track sleep, movement, and food?

No. The optional body check-in is off by default. Turn it on in Settings if you want to see how those three predictors line up with your daily energy.

Is my data private?

Yes. Lantern is private by default. We never sell, share, or train on your data. Export to Markdown or CSV any time.
