try rubbing your ear lobes a little to warm them up, I find that if I'm a little cool it has a little trouble detecting the pulse. You could also try to moisten your lobes a little.

Will this work for iphone 7?

No, works only with iPhone 4 4s is a junk

Does it work with iPhone 4?

Works only with 4 4s if u buy 5 6 Or 6s is piece Of junk

will it work on iphone 5 and ipad Air?

Heart Math has a new product with the right connector for the iPhone so that you don't have to spend the extra $35.00 for the adapter.....which they don't sell. I have not tried to use the product on the iPad air. Be aware that the ear sensor for this product has a history of failure.
