3 Must-Have SDKs for Mobile App Developers
Are you developing mobile apps? Here are 3 SDKs which we have found extremely helpful in deploying and debugging our PicCollage app for iOS/Android, which has been downloaded more than 5 million times.
- Testflight helps you deploy iOS apps to your test users.
- Crittercism helps you find and debug crashes.
- Flurry Analytics helps you monitor your app and understand user behavior.
Testflight:
Here we see the summary for a test release of PicCollage, showing how many minutes each person spent testing the app, and how many checkpoints were hit. This allows us to understand whether our app is sufficiently tested, and whether the test coverage is sufficient.

Crittercism:
Here we see a screenshot from Crittercism, showing how the number of crashes has gone done over time, as we fixed some bugs in our Android app:

In addition, Crittercism lets us know which what percentage of users see crashes, which is a very valuable metric to focus on.
Flurry Analytics:
Here we see the estimated age distribution of the users of PicCollage, from Flurry Analytics:

In addition, Flurry allows developers to define their own events, allowing for tracking of what features users are using in the app.
