For me personally, like the app which has small size and helps me a lot.
small size apps dont affect performance but can save a lot of time.
here is the list-
1)Tasker- Size/around 5mb category/tools
what it does is it make your phone automate. it triggers a task on the certain action if you are android phone user then you must give a try to this app.although its paid but there is the trial version available for 7 days. you can make your own apps also with this and there are tonnes of tutorials there for this app.[contact me for help if you want to ask any question about that.]
2)Texpand- size/around 3Mb
This app worth to be on the list of Android apps. what it does is, as the name suggests it simply expand the text on the shortcut.
here is the situation- you are irritated with typing your email id again and again just add your email id in expanding and name a shortcut to it for example- my email id is xyz@gmail.com and I create a shortcut(Vijay) so when I type this shortcut it expands into my email id.
this can save a lot of our time, you can add the address to it and much more.
3)Quora-size/25mb
