Ran into sort of an ugly problem last night pushing version 2 of my latest app MoneyPhone into production. I did all of the testing for the app on my desktop computer and used Chrome Dev Tools to make sure everything looked good on mobile and tablets. However, after pushing my V2 update/redesign to my server, I quickly found that the new version of my site looked awful on small/low-res laptops such as my 11 inch Acer Chromebook. Whoops!

So, today I’m getting started with ngrok so I can make sure to test my app on actual devices during development and avoid making the same mistake next time around. If you don’t know what ngrok is, it is a tool for exposing your local webserver (http://127.0.0.1:5000 or just http://127.0.0.1 etc.) to the greater world wide web.

Conclusion: You I need ngrok.
