Hey Product Hunt!
We've been working on Whistle for months. It started when I was training for my first triathlon and tried using ChatGPT to build a plan. It worked, but it took a ton of manual back and forth. So we decided to build something that just knows you from the start.
We're two indie developers from Vienna, and Whistle is our attempt to build the fitness app of our dreams. Hope you enjoy it as much as we loved building it.
Would love to hear what you think!
