Most health apps throw 50+ metrics at you and call it insight. Ensta gives you one number that matters: your energy, 0 to 100, like a battery for your body. It pulls sleep, HRV, and stress from the wearable you already own, forecasts your energy 24 hours ahead so you can plan hard work for when you'll have the fuel, and explains why your energy shifted instead of just reporting that it did.
Hey everyone, We built Ensta because our health apps were great at making charts and terrible at answering the one question we had every morning: do I have the energy for today, or not?
So we made the whole app about a single number. Ensta reads sleep, HRV, resting heart rate, and stress signals from whatever wearable you already wear, and turns them into an energy score from 0 to 100. A battery percentage for your body. It also forecasts your energy 24 hours out, so you can put demanding work on the days you'll have the capacity for it and ease off when you're running low.
No new hardware. It works with the devices you've got, and it's free on iOS and Android. We'd love honest feedback, especially on the energy predictions. And we're curious: what's the one health number you actually check, and which ones do you just ignore?
The hardest part by far was the recovery and energy calculation itself — turning raw signals into two numbers you can actually trust. Sleep, HRV, resting HR and stress come off different wearables noisy and inconsistent, so a lot of the work went into weighting them correctly: how much a rough night should pull recovery down, how stress and resting HR feed into the energy score, where each signal earns its place in the model.
On top of that sits the "why your energy shifted" layer — tying each change to an actual cause instead of just flashing a new number. Keeping it on the wearable you already own, and free, was deliberate: no barrier to just trying it. The 24h forecast is the part we're least sure of, so honest feedback there is gold. What's the one health number you actually act on, and which do you tune out?
