You can do most anything on ur phone now. My phone is used for probably 95% of the things I used to do on computer I would guess, thus my computer time is reduced probably by that amount or close to it.
Random example the other night I wanted to see those satellites that run in a "train". Downloaded one of the many free apps that tracks them in about 30 seconds or so. Held my phone up to the stars using the free "star chart" to see where they were going to be relative to the few stars I could see. That app let you see all the stars with names on your phone as you hold it up towards the sky. Went out at the right time and took video of them with phone (very dim here where I live due to light pollution).
I wonder if there is an app that lets you see infrared that woudl let you see them better? Everything starts like that, "I wonder if there is an app that lets you do X" and nearly all the time there is already an app for that and most of the time they are free.
There are a lot of fake ones, but you need a thermal sensor for it to work properly.

You can hack a webcam to do it though.
The European Space Agency's "Teach with space" video series explains how to convert a webcam to view objects in infrared light.
A few years ago, there used to be an inexpensive camera that had infrared mode but with certain clothing, it would produce a remarkably realistic see-through effect. The feature was dropped rather quickly.
