COMPARE
Waga vs Omi
Both keep a thought when your hands are busy. They are not the same object.
Omi
A separate wearable you add so something else can catch the note. Choose it if you want that extra device and you do not want a cap.
Waga
A cap you are already wearing. You say the thought. The phone stays in the pocket. Alia, on iPhone, keeps the note after. No subscription.
Omi fits when you want a separate device. Waga fits when the cap is already on your head.

Same job, different object
Both are for the moment your hands are busy and a thought still shows up. That is the whole overlap. The difference is what you have to add to your day.
Omi is a separate wearable. You put it on so something else can catch the note. That is a fair choice if you want that extra device and you do not want a cap. This page does not guess at its price, battery, or features.
Waga is a cap you are already wearing. You say the thought. The phone stays in the pocket. Alia, on iPhone, keeps the note after. No subscription. Pick it if the cap was going on anyway.
Questions people ask
Which one is more hands-free? Whichever one is already on you when the thought shows up. A device you forgot at home is not hands-free.
Do you need both? No. They are two ways to catch the same kind of sentence. Choose the object you will actually wear.
Does this page list specs? No. Specs change, and inventing them would not help you choose the job.
