Jose is one of the best programmer teachers out there.
This course went to a good start, ran into issues with the datepicker.
Other than that, great course to get started making profitable websites/apps
By Neil Dhand
really enjoyed learning the api
By Jochgem van Delft
Very messy App set up and not very well prepared. Also no explanation when he is coding.
By Cristian Caratti
A very interesting and real-world project with the possibility to scale up the app in the future.
The teacher is friendly and everything is well explained.
By Suzanne Atkinson
Slow start to the topic at hand, but instructor seems passionate about teaching. Three videos in and he hasn't really started with any content just reviewed how advertising works on websites
By Luis Betancourt
I liked the course, it taught me how to tie adds into any app, and create some revenue. Im happy to see how simple it is and I'm looking forward to generate some passive income.
