This time you'll get acquainted with Time Profiler and learn about the various panes and settings of an Instruments trace. * * * This is a companion discussion topic for the original entry at [https://www.raywenderlich.com/4065-practical-instruments/lessons/2](https://www.raywenderlich.com/4065-practical-instruments/lessons/2) ---

Nice video series! Just an FYI, [part 2 (Instruments 101)](https://videos.raywenderlich.com/courses/74-practical-instruments/lessons/2) doesnā€™t include the sample project in the materials, just PDFs. So the part at the end of the video about launching and exploring Instruments a little doesnā€™t make any sense. ---

Ah good point @jeffremer! I kind of imagined people could just use whatever app theyā€™re working on currently, but it would make sense to include a demo app for them to look through. Iā€™ll try to fix that this week! ---

Hi, Iā€™m using Chrome. Tried with chrome on mobile as well as my laptop. Note: Iā€™m able to get the play button for Part 1 and Part 3 but not for Part 2. ---

@karthikship Have you tried Safari instead? It works without issues for me there. ---

Hi @karthikship, Part 1 and 3 of this course are currently freely available to watch. Part 2 (and other episodes) require a subscription. There was a bug that prevented the play button from showing up, which when clicked should show that youā€™ll need a subscription to watch (it has since been fixed). Please give it another try and let me know if you experience any further issues or contact our support staff ([https://help.raywenderlich.com/contact](https://help.raywenderlich.com/contact)) . Regards, Roel ---

Ha ha @luke_parham, the ā€œprofileā€ icon is not a wrench, it is a caliper, a tool to measure precisely small distances. ---
