Before you order

Do I pay for the app on top when I buy hardware?
Yes. The devices measure, the app turns that into readiness, a sleep picture and a coach. Health Pro costs €4.99 a month whichever device you wear. If you pay monthly, it is part of the instalment until the device is paid off.
Do I need an Apple Watch?
No. Gearstack reads what your device already measures. Anyone wearing no device at all takes the strap or the band.
When does the hardware arrive?
Both devices are in preparation. On the waiting list you get a message as soon as delivery and shipping are settled, with nothing to pay upfront.
What is the difference between strap and band?
The strap is most precise during training, measured across the chest. The band tracks heart rate continuously and delivers HRV and sleep stages every night. Together they cover training and everyday life.
