title: Comparison between TestFlight Live, QuincyKit and Crashlytics
body: <p>I am going to launch my app on the AppStore and I would like to keep track of crashes and fix them as soon as possible. If possible, it would be nice to collect also some additional information about user activity and other useful stuff.
  In order to do so, I have looked for some crash reporting tools and the most interesting ones I have found are: <a href="https://testflightapp.com/sdk/live/" rel="noreferrer">TestFlight Live</a>, <a href="https://github.com/TheRealKerni/QuincyKit" rel="noreferrer">QuincyKit</a> and <a href="http://try.crashlytics.com/" rel="noreferrer">Crashlytics</a>.</p>
  
  <p>Among those three, QuincyKit should be the lightest one but the other two seem to be quite interesting since they provide more sophisticated reports and other interesting stuff.</p>
  
  <p>My goal is to have as many information as I can on any issue the user can experience, but at the same time I don't want to make the app slower or consume more resources.</p>
  
  <ol>
  <li>In your opinion and from your personal experience, which of these tools is the best one (taking into account my goal and my needs)?</li>
  <li>By using TestFlight Live or Crashlytics I would make my app too slow?</li>
  <li>Is there a risk to overload the device?</li>
  <li>Reports provided by QuincyKit are precise enough? How many information can I retrieve from them?</li>
  </ol>
  
  <p>Thanks!</p>
  
  <p><strong>Here is what I decided:</strong></p>
  
  <p>I am using Crashlytics for crash reporting (yes, it seems to be really great) and TestFlight for tracking user activity (checkpoints are really useful to find out what users generally do and figure out what the tendency is).
  I followed the instructions written <a href="http://www.grahamdennis.me/blog/2012/10/21/how-to-disable-testflights-crash-handlers/" rel="noreferrer">here</a></p>
