Easy to use. I don’t use the app. It stores 200 total readings for 2 users on a clear screen. Time, date, easy to set. It’s validated for accuracy and it’s extremely accurate. It was tested against 2 other accurate ones. Very cool feature lets you know your arm is in the right position : the heart lights up in blue- that’s when you are in the correct position. You have 5 seconds to get your arm positioned which is plenty of time. The cuff fits well, lets you know if it was too loose, or if you moved during taking the reading. LCD is easy to read. Look straight at it and there are no overlapping numbers. I’m dyslexic and have no issue with the LCD. Great compact carrying case. Directions are clear. Excellent value for it on sale! Detailed instructions in English and French pero no en español. Por qué no? Definitely recommend. It’s very quiet, you forget it’s on. UPDATED TO NOTE: it says to put it 1/2” from inner wrist crease. But not to cover the bone that protrudes on outer wrist. I would suggest going by the bone because 1/2 ” from inner crease covers that bone on me. Do the wrist test :)Muchas gracias, OMRON!
