Problem:
Heroku app gives you 500 hours dyno hours of service for free & 1000 dyno hours of service for basic plan. Which is not enough for a month or production. If you want to keep awake your Heroku app you can use Kaffeine but the problem is that your Heroku app will not be able able after 15th-21st of each month because they offer you to set 30 minutes interval.

Solution:
