[Editor's Note: This is part five of a five part series of must-have apps.]

If you didn’t know, or couldn’t tell, I’m a huge iOS fan. I currently use an iPhone 4S, which I absolutely love. I’ve been using iOS since my first iPhone, a 3G a few years ago.

Over that time, I’ve used quite a few apps, some good and some not so good. There are several apps I use on a daily basis, but here are 5 that I don’t think I could live without.

1. Bible

This app has been on my home screen since day one. I’m able to have my Bible with me anywhere I go, and not have to worry about carrying anything more than what’s always in my pockets. Having the app on my home screen also helps keep me accountable to one of my other favorite features, reading plans. Many times I try to make excuses about not spending time in the Word, but it’s a lot harder for me to do that when I always have my iPhone with me, and can study literally anywhere I am. If you don’t have this app, get it now, because the best thing about it is it’s free!

2. Tweetbot

This is the best Twitter client for iOS. Period. I’ve tried every other major client out there, and haven’t found one that matches Tweetbot’s features, as well as its elegance and ease of use. The UX and UI are incredible, and they really epitomize how an iOS app should function, and what it should look like. Tweetbot costs $2.99, but that’s definitely money well spent.

3. Evernote

If you’ve been reading this blog for any period of time, you’ve probably heard of Evernote. It basically allows you to capture anything anywhere, and then have that information available to you anywhere else. I use it to draft blog posts (including this one), store ideas I may want to come back to later, or capture pictures that I want to be searchable. Yes, Evernote can even make the text in pictures you take searchable. This is another free app, so there’s no excuse for not giving it a try.

4. Instapaper

Do you read a lot of blog posts (ahem, ChurchMag)? Then you definitely need Instapaper. It allows you to save articles for later reading, either on the web, or via the app on your iOS device. When reading with the app, it pulls out all the text and formats it for easy readability, a feature that I use for nearly every post or article I want to read. The app is $4.99, but well worth it in my opinion, especially since it’s developed by a single person, Marco Arment.

5. foursquare

Yes, I do love to checkin. I know there are many folks out there who either don’t get it, or are afraid of it, but I don’t fall into either of those categories. foursquare is my checkin app of choice. I love fighting for mayorships of popular places with my friends, and earning badges. Sometimes I can even snag discounts or special deals at restaurants or other businesses. This is another free app, so give it a shot!

What are your favorite iOS apps?
