Know Your Energy, Balance Your Stress
Delivered engagement. Coralsoft designed and built this product end to end; figures below retain their evidence level.


What was in place before we started.
Welltory uses heart-rate variability — measured with the phone camera or a wearable — to estimate energy, stress and recovery. It syncs data from 1,000+ apps and wearables to build a fuller picture, and is free with an optional Premium subscription. With 16–17M+ users and collaborations with Harvard Medical School, Johns Hopkins and ASU, it turns HRV into readable insight.

Each constraint, and what we did about it.
The insight isn’t another step count — it’s capacity: how much energy you actually have today, and whether to spend or save it.
Outcome, with the source of every figure.
By turning HRV into a simple energy battery with stress and sleep context, Welltory gave people a real signal of capacity — so they could spend energy on good days and recover before the empty ones.
How it was sequenced.
