A new report shows some key health features expected in the Apple Watch will no longer be included.

According to the Wall Street Journal, the new smartwatch will not includes features that track blood pressure, heart activity and stress levels.

CNET reports the reasons for the features being deleted from the watch are simple: They did not work or would have required regulatory approval. There just is not enough time to get approval for a watch that is supposed to come out in less than two months. Apple delayed the debut of the Apple Watch from March until April. It was thought the company could fix the health features that were not working properly, but it looks like they were not able to easily fix them.

Apple wanted its Apple Watch to have sensors to measure skin conductivity. This measure would help the watch monitor heart rate and stress levels. Apple ran into problems with the sensors when users had hairy arms, dry skin or wore the watches tighter than others. This led to mixed results.

Apple also wanted to test blood pressure and oxygen levels in the blood. Results proved inconsistent, and this feature had to be scrapped. Additionally, if the blood pressure measure was considered medical advice, Apple would have needed approval from the Food and Drug Administration.

Although Apple might be disappointed in the missing features, the company is trying to market the watch as an all-around device. Apple wants potential customers to know the watch can act as a supplement to the iPhone, be used as a payment method using Apple Pay and has voice-activated controls.

Wall Street analysts predict that between 12 million and 15 million Apple Watches will be sold in 2015. Apple plans to make 5 million to 6 million available during the watch's first three months.
