App Development Resources
I created this resource page where you can always find helpful tools, media, and resources for your app development needs. I will be continuously updating this page with useful and helpful links, so be sure to bookmark this page for future reference!
Disclosure: A few of the links below are affiliate links where, if you decide to purchase, I may earn a small commission (at no additional cost to you). I add resources to this page not based on how much I might earn from them, but on my experience with them and how helpful they might be to your app business. Please do not spend money on any of these sites unless you firmly believe they will help you and your business. – Chris
Ad Networks – currently using
Currently, I earn most of my income from advertising networks in my Corona SDK apps. After multiple attempts to find the best performing ad networks through real-world testing, these are the ad networks that I found perform the best and am currently using in my iOS and Android apps.
- Vungle – Video ad network. I like Vungle and have had very good results with them.
- RevMob – Full-screen interstitials and banner ads. Used to be my “go-to” network but has been up and down lately. Still very highly recommended.
- Playhaven – Playhaven has performed very well for full screen ads and app walls. They have some other cool features to run house ads, and other marketing tactics.
- Adbuddiz – I recently started adding this into the mix on occasion with good results.
For me, these companies have far outperformed any other ad networks both in eCPMs and overall earnings. If you’re using another network, I encourage you to try some or all of these to test your results. Just remember, it’s all about what works best for YOUR apps! And it will likely change over time!
Ad Networks – previously tested & used
I have used these advertising networks in the past with some limited success. I currently find better eCPMs and overall earnings from the list above.
- Tap for Tap – I had OK results with TapForTap and also tried their cross-promotion network. Overall didn’t perform well enough and the cross-promo network did a better job of eating into earnings that I otherwise would have had than leading to downloads. I also didn’t have any success with their credits system (where you earn taps on your apps by gaining taps to other apps). I have 291,370 credits and haven’t seen one of my banners run for months. Overall, I’d steer clear.
- Inneractive – I started using this ad moderation service when I changed development environments. I got mediocre results and found that getting paid regularly and on-time was not happening often enough. If I start to hear that payments are arriving on-time again, I may throw them back into the mix for a few tests.
- Chartboost – I tried this for a very short time with very poor results. I’ve heard others have very good earnings from them but personally did not see anything close to the other networks I’ve tested.
Ad Networks – not tested but on my watch list
- StartApp – I’ve read good things about this ad network. They have very unique ad units that tend to get more attention than standard interstitials. CPMs look to be promising (I’ve read reports of $3-$6 CPM). The bad news seems to be they don’t have support for Corona at this time. I’ll be keeping my eye on them.
- iTunes Affiliate Program – If I link to the App Store for anything (whether to my own apps to ask for reviews or to the store itself) I always, always try to use an iTunes affiliate link. It doesn’t generate a huge amount of income, but it adds up over time. You’re leaving money on the table if you link to your apps and don’t use an iTunes affiliate link.
- Zazzle – Why not sell T-Shirts and other products, right? I don’t make a ton, but it’s kind of fun and it does add up over the year. I do prefer Zazzle’s user interface and overall service over Cafe Press.
- Cafe Press – I sell T-Shirts here as well. I like CafePress, but it is dated and more difficult to use than Zazzle.
If you want to know what people are doing once they download and install your apps, you absolutely NEED an app analytics service of some kind. To be honest, I’ve done a very poor job of event tracking to date and am a bit embarrassed to even admit it. Expect future improvements and a report or two on what I learn. Corona SDK used to have some analytics built in, but they recently turned those off so we’re on our own.
- Flurry – Flurry does a great job of tracking everything from users, technical specs and demographics to specific in-app events. Recently acquired by Yahoo, it remains to be seen how it will change in the near future. Works very easily with a Corona plugin.
- Upsight – Upsight analytics help you track virtually everything in your apps. They also offer some great marketing tools.
- AppAnnie – More for app store analytics, AppAnnie has tools to monitor app downloads, revenue, rankings and store statistics. A great resource to monitor your apps and perform competitor analysis. Can also plug in your ad networks to track earnings all in one place — for a while this was working perfectly and was a really awesome resource for tracking ad income all in one place. Lately, however it has not been working properly and support tickets seem to go unanswered at worst and unresolved at best. Worth using but keep expectations low until they resolve some issues.
- DreamHost – Why do I think DreamHost is so dreamy? Because they have one of the easiest to use control panels, super simple 1-click installs, automatic upgrades, and their uptime and reliability has been far better than any other web host I’ve ever used. (And I’ve tried a few!) Whether you need a website to promote your apps, or a server to manage scripts or dynamic content within your apps you’re going to need a great web host that won’t slow you down. I HIGHLY RECOMMEND DreamHost for your web hosting needs.Click this link to get a special $10 discount on DreamHost web hosting!
App Store Optimization (ASO)
- App Store Optimization Course – If you want to learn ASO, you need to learn from the best. Gabriel Machuret is the best of the best when it comes to App Store Optimization. I highly recommend his course if you want to supercharge your ASO and rank your apps well!
- Sensor Tower – Sensor Tower helps you track daily keyword rankings for your apps and competitor apps. A great help for app marketing and keyword optimization. Be sure to check out their blog if nothing else — as they share some really great tips for developers.
- SearchMan – SearchMan helps with App Store optimization and keyword development. Super easy to use. GREAT to help you find keyword possibilities that you may have overlooked. I recently stumbled across this one and am finding it very useful.
- OneLook – This a reverse dictionary that I like to use to help me find keywords that I otherwise might not have thought of. It’s a really great tool to use in combination with Sensor Tower and SearchMan.
If you haven’t tried outsourcing yet I encourage you to give it a try. You probably struggle (like I do) with having enough time to accomplish all of your goals for one project, let alone the list of projects you’d like to see completed. You can find app developers, designers, copywriters, and people to help you do just about anything. I was surprised just how inexpensively you can find someone to help you achieve your goals!
- Odesk – I’m a big fan of hiring people from Odesk and have had 100% satisfaction thus far!
- Elance – I haven’t hired anyone off of Elance, but it’s another good option.
- Freelancer – Another great freelance option.
- 99 Designs – Let designers compete for your project and SEE the ideas before you buy!
