Ask HN: How do you monitor competitors in your industry?

Hello everyone, I'm looking for effective ways to track competitors in my role as a Chief Product Officer at a start-up. We have several competitors, and I'd like to keep tabs on their progress and product updates. Currently, I just have their apps installed on my phone and occasionally visit their websites for new information. I feel there must be more efficient methods to stay informed. What tools or strategies do you recommend?
