I just launched my first product: Trello Reminders.
It's goal is to allow Trello users to set reminders on cards and receive email notifications when the time is up. I hope to evolve it over time to become an even better extension that helps Trello users, especially when it comes to reminders.
It's been a long way getting to this point and still I feel there's a lot of stuff lacking in this version.
Please, provide suggestions to help me improve and reach out to potential customers.
