If you're like me, and have a non-jailbroken iPhone based on principle (or at least for while the warranty is active) yet are a tad cash strapped, the App Store can either be your best friend, or your most confusing enemy. There are a ton of free apps and games, and not just lite versions, that are actually awesome. Finding them in the madness of the App Store can be a challenge though, so here are a few ways you can find some quality guilt-free entertainment for your iOS device. Note, this list is primarily useful for finding apps for the iPhone and iPod Touch, not necessarily for the iPad or desktops.
The Top 25 List
Beyond the obvious looking at what's on the top 25 list for free games, be sure to read the descriptions for the games and the developers that are on the list. A lot of times, developers release multiple free games at a time, or put multiple games up on sale for a limited while and that's usually mentioned in the game description. For example, right now, Donut Games is making 3 of their games free each day for a week. Every day it's a different game that they make free and some of them are actually entertaining, even if they haven't made it to the top 25 list.
Free App Tracker
Free App Tracker is a free application that tracks every single price change that happens in the App Store. It's pretty useful for seeing games that have fallen in price, or have become free. It sorts information pretty intuitively. You can see which apps have become free sorted by recent, popular and random (for if you're feeling lucky) as well as which apps have dropped in price (sorted in the same 3 categories). If you find an app you like and you want to download, it links you directly to the app's page in the App Store. The other interesting feature in Free App Tracker is if you think an app is going to become free in the near future (think Angry Birds Seasons), you can add it to a track list. The track list will notify and show you both, if the app of your choice has been discounted or has become free. Pretty cool paisa vasool. Another application that does exactly the same thing is Free App Genie. I like the interface of Free App Tracker better but if you like the interface of Free App Genie more, you're not losing out on functionality if you choose to use that instead.
Tracking price drops and new freebies
Free App A Day
You'll see a lot of Free App A Day apps on the Top 25 list. Free App A Day is an awesome service which makes apps free for a day at a time. It's like iTunes' free single, music video, video rental of the week feature. Sometimes, after the apps become free they stay free, but a lot of times they go back to being paid apps. Some awesome apps that have been free in the past are Deathworm (usually costs $0.99, approx Rs. 45) and Ovenbreak (usually costs $1.99, approx Rs. 91). Free App A Day is available in the App Store for free but usually its games and apps are on the top 25 free list also.

So there you have it. These are three pretty efficient and easy ways to score some decent free apps. If you know of any others, mention them in the comments section below. In the meanwhile, enjoy downloading free stuff legitimately!
