Today’s insight
for Allen, Reva’s first user
You’ve absorbed 192 TSS over 4 active days. TSB is −9.6 (tired) and HRV at 48 ms is below your 7-day baseline. Today: keep it Zone 2 only — skip the intervals.
Built in public
“I’m building Reva because I was tired of opening five apps every morning to piece together my sleep, recovery, and training. It starts as my n=1 pilot — open journey, open data, open build.”

Today’s recommendation
Generated 6:32 AM
HRV is 12% below your 7-day baseline. Walker et al. (2024) found Zone 2 cardio improves recovery 19% faster than full rest after low-HRV days. We’ve queued a 45-min easy ride.
