Challenges we ran into

Everything looked sorted, initially. We made 3 different parts i.e. MediTime, the key app, and the weather forecasting app, and later agreed to combine these 3. The 3 apps work perfectly well on their own. We discovered difficulties at the time of combining them and were unable to integrate them properly. We were also unable to fix this problem because of the time constraint, as well as we were unable to incorporate a few other items we expected, such as adding a few amazing APIs that could customise our app. 
Even, we couldn't incorporate it with our app because it was a paying chatbot, the assistant chatbot we created.
Overall, due to a lack of awareness about API integration with our applications, we faced these problems.
But as any person learns from his/her mistakes, we did as well. Got to hear a lot from the judges and coaches who kept coming out of the tables wondering if we were having any big logistical challenges and proceeded to inquire for us.
It was a great experience learning and exploring .
