Michael Seid has built Text Nina, a simple text-based to-do list service that uses Twilio SMS, allowing users to easily remember tasks without having to download an app. The service operates with just a few lines of code and is designed to be unintrusive, using a phone number interface instead of traditional app features. As the CTO of Naytev, Seid aimed to create an alternative to list apps that are often cluttered and overwhelming, by providing a clean and simple solution for managing tasks.
