Hi Product Hunt community! I'm Keith, the founder of 150bar dive log app (a not-for-profit passion project). I am excited to announce that we are launching our beta, to empower every diver to be a citizen scientist through logging their dives! WHY 150bar? It started as a personal pain point - logging dives in a book is boring. I can't upload pictures, tag my buddies, and I have to make sure my dive instructor physically stamps it. When I forgot to bring my dive log book on a dive trip, I had to resort to scribbling logs on loose pieces of paper. Also, after a dive, divers are quick to get back to their phones and cameras, rarely anyone starts logging in their log book. "Why can't someone just build a dive log app?!" I thought. Well, apparently many people have! I must have tried over 40 different dive log apps. Not surprisingly, major certification bodies like PADI and SSI have their own dive log apps too. The problem is however, they often crash or have very bad/confusing UI :( Thus, I decided to take matters into my own hands and assembled a small team of engineer and designer to build 150bar. FROM LOGGING TO CITIZEN SCIENCE As we started scoping the product, it became apparent that what we are building can grow to be so much more than a dive log, that the data contributed by divers could be used to track underwater temperature at popular dive sites over time. As a diver, I've always been saddened when I read news about the impact of climate change and how coral bleaching is occurring at an increased rate. With dive log data contributions from divers like you, we can use the aggregated temperature and depth data from thousands of dive logs to predict the likelihood of coral bleaching events at certain sites, and work with community leaders to take preemptive measures. That is why, we've made sure to get the data engineering architecture right from day 1. We are really excited to take the next step to get 150bar into more diver's mobile phones now. I really look forward to hearing your feedback on our product, and I will be around to answer any questions you might have. P.S. Given the current Covid-19 situation, even if you are not going on a dive trip anytime soon, it will be great if you can upload your dive cards on the app so you don't have to worry about forgetting to bring them on your next trip anymore. Stay safe and healthy! Best, Keith
