Mobile App Tools (SDKs) Simplified: How to Choose the Best For Your App

For some, the world of mobile SDKs (Software Development Kits) is fascinating, perhaps even straightforward to comprehend. But for many, it’s like going down the rabbit hole. So many types, versions, functions and categories to sift through – serving different needs – like analytics, advertising, attribution, user engagement, customer self-serve (like chatbots), monetization…you get the idea. The more you start looking, the deeper and deeper you get.

To provide a point of reference, SafeDK 2018 data shows that the average number of SDKs in an Android mobile app is around 18 – and usually higher in gaming apps. 

So, let’s cut to the chase. Does your app really need that many SDKs? How do you figure out which types you need and which ones will best serve your app product’s objective?

That’s why we’ve put together this simple (or at least simpler) guide to help you identify where to focus your app SDK selection efforts – or, at the very least, provide a starting point. We’ll go through the top 3 types of mobile app SDKs:

  • Mobile App Attribution
  • Mobile App Analytics
  • Mobile App Engagement

Top 3 Types of Mobile App Tools

1. App Attribution SDKs

If you’re doing app marketing (which we hope you are!), it’s critical to know how effective your efforts are and which aspect of the marketing is working best. Not only is this important for obvious monetary reasons, but it keeps you from wasting valuable time and energy.

This is where a mobile attribution tool comes in. Having an attribution SDK in place helps to attribute an app install to the source of user acquisition and the marketing campaign on a single platform. You can see exactly which ads on which channel delivered which users, right down to the exact campaign creatives those users see. By keeping track of the attribution source, you’re able to optimize budgets to identify which source is bringing the highest quality users and adjust accordingly. 

What factors should you evaluate when selecting the right mobile attribution tool for your mobile app?

  1. Attribution methodology
  2. Dashboards & reporting
  3. Retargeting attribution
  4. Uninstalls reporting
  5. Fraud detection
  6. Integrations with self attributing networks (like Google Ads, Facebooks etc.)
  7. Platform pricing based on your needs & budgets

As for how many you need for an app, you’ll want to pick one attribution SDK that best suits your needs, based on the pricing and usage.
