WITU vs Apple Watch Ultra 2
Apple Watch has the most powerful app ecosystem and an on-demand single-lead ECG. But it's an expensive smartwatch with no continuous ECG and no blood-test integration.

| Blood tests | Yes — AI parser for lab reports | No |
| Materials | Sterling silver 925 · natural agate | Titanium + silicone |
| Ecosystem | 5 devices, one shared core | Watch + the iOS ecosystem |
| Accuracy in sport | Chest-strap ECG monitor, 99.6% | Good, but optical |
| Sleep analysis | Ring + bracelet, 5 phases | Basic tracking |
| Battery life | up to 7 days (bracelet) | ~36 hours |
| Price | from $399 one-time | from ~$799 |

What to choose
Need an all-in-one smartwatch? Apple is unrivaled. Need a jewelry-grade tracker with medical-grade optics, long battery life, and blood-chemistry context without being tied to iOS — with real, continuous ECG available in the ecosystem via the Patch? That's WITU's niche. Many people wear both.
WITU focuses on health, not smartwatch features — hence the different price and battery life.
