7 EXTREMELY USEFUL ANDROID APPS YOU MUST HAVE

Plenty of Android apps are available in Google Play Store. But every Android app doesn't have high-end smartphones like Samsung Galaxy S6 to accommodate lots of apps. Many of us are frustrated with the lack of internal memory and all. Hence, we avoid junk apps as we are always limited to install apps which are very useful.  Here, I am sharing 10 Android apps which are extremely useful.

I haven't included highly popular Android apps like Facebook and Whatsapp because you already have them installed on your Android phone. Note that the list given below is purely based on my Android experience. So, pardon me if you find any app not extremely useful.

1. C CLEANER
Android apps have a bad habit of depositing junk cache which eat up the internal memory of your smartphone. So it's necessary to clean up your phone regularly to free up internal memory, otherwise you may run out of memory any time. C Cleaner from Piriform is considered as one of the best apps to free up your internal memory.

Here are some features of C Cleaner:

  • Remove junk safely to speed up your phone.
  • Clear app cache, unwanted folders, clipboard content, old call logs etc.
  • Streamline your Android device.
  • Easily uninstall unwanted apps.
  • Free from annoying ads and clutter.
  • Small size.

Reasons may be various, but we always want to note down some points or list in our smartphone. Many phones already have inbuilt note taking apps, but usually they are not well crafted. Google Keep is a colorful, but simple note taking app from Google itself. It has a simple interface and it's a breeze to use.

Here are some features of Google Keep:
  • Add lists, notes and photos.
  • Labels to quickly organize notes.
  • Colorful and simple user interface.
  • Share your notes and ideas with friends.
  • Set location based reminder.
If you are looking for a note taking app with more functionalities then you may choose Evernote.

3. ES FILE EXPLORER
In order to manage your photos, videos, documents, apps and files, a file manager is a must for Android smartphones. Many smartphones come with preloaded file explorer apps which have limited functions and features. If someone ask me which is the best file manager for an Android phone, I would say it's ES File Explorer.

Here are some features of ES File Explorer:

  • Manage your files with several options like cut, copy, paste, delete, send, hide etc.
  • Manage your installed apps.
  • Built-in RAR and ZIP support.
  • Manage your smartphone files with your PC.
  • Cloud support.
Alternatively, you can also choose popular file managers like this too. 

4. XENDER
Transferring a big media file from one Android phone to another one through connectivities like Bluetooth is a painfully slow process. Here, Xender comes to help you because it uses WiFi/hotspot of your phone (no internet data) to transfer files within few seconds. I had already posted a blog post defining how to use Xender.

Here are some features of Xender:
  • Transfer everything including apps.
  • Supports group sharing up to 4 devices.
  • Supports cross-platform transfer.
  • PC support.
  • No USB, no internet and no data.

Ebook reading is considered as a part of smartphone life. There are many ebook readers in Google Play Store and I prefer UB Reader. Usually, ebook readers read only files in epub format but UB Reader can read books in both epub and PDF format. Hence, UB Reader can act as ebook reader as well as PDF reader and you don't need to install two apps for these purposes.

Here are some features of UB Reader:
  • Open epub/pdf files from file explorers.
  • Highly customizable with font size, brightness, page orientation etc.
  • Integrated file browser to import ebooks.
  • Allows you to add shelves.
  • Available in 12 languages.
Alternatively, you can also go for ebook readers like Aldiko Book Reader.


Writing in smartphone becomes simpler with Google Handwriting Input. This app from Google is extremely useful and is a boon for non-English people. For example, my mother tongue is Malayalam and writing Malayalam with the keyboard was a tedious job because this language has many letters. With Google Handwriting Input, I can write Malayalam by simply moving my fingers.

Here are some features of Google Handwriting Input:
  • Support 82 languages.
  • Writable with or without a stylus.
  • Compliment for touchscreen typing.
  • Input emojis by drawing.
  •  Support printed and cursive writing.
7.  TWILIGHT
We are used to look into our smartphone for a long time for purposes like chatting, browsing, reading etc. Looking into a smartphone for a long time, especially during night time causes strain in our eyes. This strain may eventually leads to sleeping problems. Twilight is a small Android app which protects your eyes from strain. You can read my blog post about Twilight from here.

Here are some features of Twilight:
  • Make your night reading more pleasant.
  • Works according to the sunrise and sunset time of your location.
  • Simple user interface.
  • Small size.
  • Also available for PC. 

I find these seven apps are extremely useful for me. There are also many other useful Android apps. Share them with us using the comment section.
