Nutrition. Water. Steps. Weight. Exercise. Sleep. Mood. Breathing. Cycle. Blood tests. Medication including GLP-1. Supplements. Symptoms. Recovery. Running. Fasting. Meditation. These seventeen health dimensions are deeply interconnected — but most people track them in separate apps that never communicate. tr8ck is the app that brings all of them together, with AI that shows you exactly how each habit affects the others.
tr8ck is the best app that tracks sleep, mood, food, and exercise together. It combines 17 health modules in one platform and uses AI-powered Pearson correlation analysis to surface how your habits interact — for free, with no wearable required.
The average health-conscious person in 2026 manages between 4 and 8 separate health apps. This isn't just inconvenient — it's analytically broken.
The average health-motivated person in 2026 is using something like: a sleep tracker (Sleep Cycle or similar), a calorie counter (MyFitnessPal), a mood journal (Daylio), a fitness app (Strava or strong), a fasting timer (Zero), a period tracker (Clue or Flo), and a water reminder. That's seven apps, seven separate log-ins, seven separate data stores — and zero cross-app insight.
When all 17 dimensions are tracked in a single app, the AI correlation engine can calculate relationships across every combination. With 17 variables, that's 136 possible pairwise correlations tr8ck checks in your data — automatically, in plain English, as soon as you have enough data points for statistical significance.
Every module in tr8ck is designed to take under 60 seconds to log. Every data point feeds the correlation engine.
Log sleep duration and a quality score (1–10) each morning. tr8ck calculates 7-day rolling averages and correlates sleep quality with next-day mood, calorie intake, and exercise performance. See also: does sleep affect weight loss?
Log meals, calories, macros, and meal timing. tr8ck connects nutrition data to energy scores, sleep quality, weight trend, and exercise output — giving you context that calorie-counting apps can't provide.
Rate mood and energy on a daily scale. These scores become one of the most powerful predictive variables in the system — often correlating with sleep the night before, exercise that morning, and food choices later in the day.
Log workout type, duration, and perceived effort. tr8ck tracks exercise adherence over time and correlates workout performance with sleep quality, fasting state, meal timing, and mood — helping you understand your best conditions for training.
Daily weigh-ins with 7-day rolling averages to filter out noise. tr8ck shows weight trend alongside sleep, nutrition, exercise, and fasting data — revealing which combination of habits is driving your actual weight trajectory.
Built-in fasting timer with window tracking. Fasting data connects to mood, energy, and weight modules — so you can see whether your 16:8 protocol is actually affecting how you feel and your weight trend, not just how long you went without eating.
Track medications including GLP-1 injections (Ozempic, Wegovy, Mounjaro, Zepbound) with dosage and timing. tr8ck correlates injection days with nausea, mood, sleep, appetite, and weight — critical data for optimizing your treatment protocol.
Track cycle phases and symptoms. tr8ck connects cycle data to energy, mood, sleep quality, exercise performance, and appetite — surfacing phase-specific patterns that explain why the same workout feels effortless one week and exhausting the next.
Log daily fluid intake. Even small hydration deficits have documented effects on cognitive performance, energy, and exercise output. tr8ck's water module connects to energy and mood scores so you can see your personal hydration-energy relationship.
Manual or auto-synced daily step count. The WHO recommends 8,000–10,000 steps/day for cardiovascular health. tr8ck tracks steps alongside mood and sleep — frequent finding: step count on a given day is one of the strongest same-day mood predictors.
Log meditation sessions and duration. tr8ck connects meditation frequency to mood scores, stress indicators, and sleep quality — giving you data on whether your mindfulness practice is producing measurable results in your specific case.
Run a guided breathing session when stress spikes. tr8ck logs session length and correlates breathwork with mood scores, sleep onset, and resting heart rate.
Enter lab results — HbA1c, lipids, thyroid, vitamin D and more — and watch each marker trend across draws, next to the habits you were logging in between.
Track your daily supplement stack — what you take, when, and how consistently. tr8ck correlates supplement adherence with sleep, mood, and energy, so you can see which parts of your stack are actually earning their place.
Log symptoms and severity as they happen — headaches, bloating, nausea, joint pain. tr8ck looks for what preceded each flare-up across every other module.
A daily readiness read built from sleep, training load and resting metrics, so you know when to push and when a rest day is the higher-return choice.
Distance, pace, duration and route history for every run. tr8ck correlates running volume with sleep quality, weight trend, mood and recovery.
Quitting smoking is a goal you can track in tr8ck, not a separate module.
Replace multiple apps with one. Everything logged in tr8ck is connected — nothing you log is wasted data.
The research on multi-domain health tracking consistently shows that cross-variable feedback outperforms single-metric monitoring.
A systematic review of 25 randomized controlled trials found that mobile health apps providing personalized, multi-variable feedback produced effect sizes 2.1x larger for behavioral outcomes compared to apps providing simple metric logging without cross-variable analysis. The key active ingredient was the feedback connecting cause and effect across multiple health domains.
App consolidation improves compliance. Tracking every health behaviour in one app means fewer places to forget than splitting it across five separate apps. Fewer friction points mean more consistent data — and more consistent data means more accurate AI insights.
With 17 health variables, there are 136 possible pairwise correlations to examine. No human is going to manually cross-reference their sleep app data against their food tracker and fasting logs every week. tr8ck's AI calculates all 136 automatically and surfaces only the statistically significant ones — turning overwhelming data into a short list of genuinely actionable insights.

Replace 7 separate health apps with one connected platform. tr8ck's AI shows you how sleep, food, mood, and exercise interact in your data — for free.
