The app works forever. For each hour, the bot opens a new instagram hashtag which is available the list of hashtags in an array.
Then it likes 25 most recent posts of the hashtag and add 7 comments after the 25 likes. After that the app waits for one hour then it will do the same thing again forever.
Note: Instagram likes and comments are limited that's why we put limited likes and comments for each hour. The bot likes 600 posts and 168 comments for each day. The time between likes is 15s.
You should just provide your instagram username and password inside the source code and done. Note: the app is only developed for educational purposes not for spamming on instagram.
