For those with smaller phones with only 8 GB of storage or not there are two alternatives to installing apps you may want to be aware of; Instant Apps, and Progressive Web Apps. I won't cover Instant Apps here, because they are only for certain phones, and that is between the device maker and Google. Plus the installation process is really confusing.
The other method, which is a bit clearer, is Progressive Web Apps. Anyone running Chrome on Android can do this. Search for your service in the Google app. Click on the listing for the website. The site should ask you if you want to add it to your homescreen. Answer Yes. You now have the web page, as an app, in your app listings. The size should be less than 1 MB.
Not all Progressive Web Apps ask to be added to the homescreen. You can save the web page to the homescreen, and that accomplishes the same thing. And you will get some functionality.
The difference between a web site you just saved to your homescreen, and a web site that actually installed a progressive web app, is one you can see in your settings. Go to settings, go to apps. Wait a bit for the size of your apps to populate. The progressive web apps, are the apps that are less than 1 Mb in size you've installed to your device. Do not confuse these with apps like your note taking app and your calculator app, that come installed onto the device from the manufacturer.
So I have had success getting these Progressive Web Apps onto my device. I've given up on Instant Apps because I am no longer using the device that Instant Apps are compatible with. You can also visit
outweb.io on your device and see what they have available.

This does not sound like much. But keep in mind that one can use Flipboard for news, as opposed to using Google Play Newsstand or Currents, iHeartRadio for music, as opposed to any built in apps and Instagram goes without saying. Twitter is a bit tricky. You can go to mobile.twitter.com and just add it to your homescreen. I should have asked me upfront, and normally when a site does not I have no guarantee it actually installs as PWA but this one does. Telegram make sure you go to Telegram Web.
Rule of thumb is that if you add a website to your homescreen and you do not get an actual icon, but instead a letter that is the first in the name of the site, you probably did not install a progressive web app, but just a link to the homescreen.
So with the aforementioned list of web services, for around 1.6 MB, a user can gain access to like 1 GB worth of applications. You just need to make sure that Chrome is installed, and it is up to date. I say 1 GB because your average app is going to balloon to 200 MB as soon as you start using it on a regular basis. The savings through Instagram and Twitter alone make this worth exploring.
