I may be biased as I'm the founder, but I've got to share the word about how useful you're going to find this tool once you start.
ProdPad is a tool for product managers and their teams. It helps them gather ideas and customer feedback, prioritize them and turn them into specs that can be sent to development, and create a roadmap.
It's a massive time saver, and is hooked into all the tools that teams commonly use, including Slack, Google Apps, JIRA, Trello, Dropbox and more. And at the end of the day, it'll help you build the right things and create products that your customers will love.
ProdPad is used by 10,000s of product managers around the world, building all sorts of products, whether digital, hardware, or service-oriented.
