Guide
One app to track sleep, mood and nutrition — together
The usual setup is three apps: a sleep tracker, a mood journal, a calorie counter. Three subscriptions, three logins — and zero connections between the things that most obviously affect each other. This guide covers what a combined tracker actually gets you, how Lamplit does it, and which dedicated apps are still worth it.
Why together beats separate
Food shapes sleep
Late meals, alcohol and caffeine show up in your night — but only if the app that knows what you ate is the app that knows how you slept. Separate apps each see half the story.
Sleep shapes mood
Short nights surface in tomorrow's mood, often with a delay. A mood journal alone records that you felt low; paired with sleep data, the pattern becomes visible and actionable.
One data set, real correlations
When sleep, mood and meals live in one place, cross-domain analysis becomes possible — Lamplit's Genie surfaces these patterns and cites peer-reviewed research when it explains them.
How Lamplit covers all three
Nutrition
Log meals from a photo with macros and micros, scan barcodes, estimate full nutrition for recipes, and get personalized calorie and macro targets — with a real free monthly allowance.
Sleep
Import sleep automatically from your watch or ring via Apple Health / Health Connect (Pro), or log it manually — duration, quality and trends over up to 12 months.
Mood & journal
A three-step mood check-in and three guided journal prompts — under five minutes a day, and enough substance for real pattern detection.
The connections
Cross-domain insights link the three: how eating windows affect sleep, how sleep affects mood, what your data actually supports — with citations, not vibes.

Honest alternatives — including keeping a stack
A combined tracker isn't automatically the right answer. Here's the honest landscape:
Bearable
The closest single-app alternative — symptom-first, built for chronic illness, with mood, food and sleep factors. Deep logging, but charts you interpret yourself and no AI.
Exist
The indie correlation engine: syncs sleep, activity and mood from other services and finds statistical patterns. No native food logging and no coaching, by design.
A wearable + its app
Oura and Whoop cover sleep and recovery beautifully, with shallow meal and mood companions — and $69–359 a year on top of hardware. Lamplit imports their data rather than competing with the sensors.
Apple Health / Health Connect alone
Free and already on your phone — a genuine aggregator, but no journaling practice, no guided anything, and no analysis that explains what the numbers mean together.
The classic three-app stack
Sleep Cycle + Daylio + Yazio is a fine stack if you want best-in-class depth in each domain and don't need them connected. Expect roughly $120+ a year and three sets of ads or upsells.
