In some countries, it's become possible to leave your wallet at home while you go out for dinner and drinks or to do the shopping, thanks to payment apps using the NFC chip in your phone. — dpa

No one thinks twice about pulling their smartphones out to check the time, do some calculations, set an alarm or call someone these days. But less than three decades ago, you would have needed four different and not-so-portable devices to do all of those tasks.

Just how many devices has the smartphone replaced in our lives? Here's a far-from-comprehensive list of things your phone has replaced.

Wallet: A growing number of stores around the world allow people to pay by holding their phones over a special reader at the checkout and using their Google Pay or Apple Pay account. The NFC technology used is usually the same that's found in bank cards to make contactless payments. An NFC chip is standard in newer smartphones; iPhones have offered it since 2015's 6 model.

Spirit level: Is the picture frame crooked? In the old days you needed a spirit level, now you just need your phone. Android users can download one of many apps offering this capability, while iPhone users have had the capability built into the iOS since version 7.

Tape measure: Any iPhones after the 6s can scan their surroundings and measure objects. Just hold up the camera as if you're going to take a picture and define the start and end points of the object you're trying to measure. Several measurements are possible, such as the height and width of a plant or special shapes like a rectangle. Google offers the AirMeasure app for those who without an iPhone.

Video game console: Modern chips and fast internet make smartphones appealing to game developers. The A14 chip used in the iPhone 12 is said to be over 3 gigahertz, while Nintendo's Switch is only about 1 gigahertz when playing games. As long as you have fast internet access and a newer smartphone, you have access to, and can play, thousands of video games by subscribing to platforms such as Steam.

Dictionary: While the technology for simultaneous translation is not yet there, you won't be left unable to communicate as long as you have a smartphone. Google's free Translator app can translate a menu, for example, just by using the camera function. According to the manufacturer, such capabilities are offered in 94 languages.

Remote control: No longer do you have to get up to change the TV station when the remote control has gone missing: Televisions that are connected to the internet can be controlled with your smartphone and your home internet connection. Samsung, for example, offers the Smartthings app that allows you to control smart devices, from the dryer to the TV. There are also apps for universal remote control.

Pedometer: Fitness devices were all the rage for a while, counting your steps and nudging you to hit your health goals. Now, your smartphone can do that too: For Androids, there is the "Google Fit" activity tracker, while for iPhones there's the "Health" app that's already included since iOS version 8. Both apps count steps, and measure and store distances covered when walking or running. If you prefer an external solution, the Pacer app works on both systems.

Heart rate monitor: There's no need for a smartwatch to take your own pulse - there are various apps that can do that. With Preventicus Heartbeats, you just put your pinky on the phone camera; the app maker promises that your pulse can be measured using video signal. – dpa
