One of the funny things about modern bits of tech that we all use every day, like the iPhone, is that they often contain features that we don't even really know about.
Apple jams so much into its phone nowadays that you might be overlooking some simple settings and features that could be incredibly useful, so we've gathered a handful of potentially helpful examples.

White noise for concentration
Your iPhone can actually produce soothing background noise whenever you like, with a few quick taps.
All you need to do is head to Settings, then tap on Accessibility and then on Audio & Visual. From here, tap on Background Sounds.

You'll be able to turn background sounds on and off, select what sort of noise is played (from rain to simple static) and edit the volume, which is so handy.
Measure things easily
A few years ago Apple added a new app to iPhones, one that is built into all iPhones now - Measure.

This handy app is a great way to do some measuring if you don't have a physical ruler present. It uses the iPhone's camera system, and takes depth measurements to ensure that it can give you accurate readings.
It might not be something you'd want to rely on for construction but, in a pinch, it's a superb backup for taking quick measurements.
Customise your silent mode
While it used to be a more simple block for all noises, silent mode is now more customisable on iPhone, letting you choose which contacts penetrate through its veil.
Advert
To let someone ignore your silent mode or focus options like Do Not Disturb, just head to your Contacts app and tap on a contact.
Once you see their details, tap Edit at the top-right of the display, then tap on Ringtone. Here you'll see a toggle to turn on Emergency Bypass.
If you turn this on, you'll get sounds and vibrations when this person contacts you, which is ideal for those who you know need to get through in emergencies.
Track your activity using just your iPhone
While having an Apple Watch, Fitbit or any other sort of wearable might be ideal for those on a major fitness journey with goals, your iPhone can do a lot more than you might realise.

If you open up the Health app you'll see that your phone is actually tracking your activity in way more detail than you might first assume, including mapping your whereabouts and keeping count of your step count each day.
This data is local and private, and it can be a huge aid if you're trying to get into better shape - plus it's a great way of reflecting on what you got up to in a busy week.
