Strong, Hevy, and Jefit are great for logging sets and reps. But none of them tell you why Tuesday's session destroyed your sleep, or why morning runs leave you in a better mood than evening lifts. tr8ck does.
Start free →A standard workout tracker is best for logging exercises, sets, and reps. tr8ck is the better fit if you want training plus 16 more health modules — sleep, mood, medication, nutrition, fasting — with AI that shows what your workouts actually did to your body. Free covers 4 modules; Pro is $4.99/mo, Premium $6.99/mo adds AI insights.
You can see your bench press increasing — but can you see how it's affecting your sleep quality? Your mood two days later? Your energy on rest days?
Intensity, timing, and workout type all affect sleep architecture differently. Evening HIIT often delays sleep onset. Morning strength training may improve deep sleep. Workout trackers don't capture this connection.
The mood benefits of exercise are real but vary by person, type, and intensity. Some people feel great after heavy lifting; others feel drained. tr8ck tracks which workouts actually improve your mood and for how long.
Without a $300 Oura Ring or WHOOP, there's no HRV data. tr8ck uses your sleep quality scores, next-day energy ratings, and mood logs as a proxy for recovery quality — no hardware required.
