Share the viz in three steps! 1. Write your dive log and report the ocean conditions 2. Fellow divers share their logs as well 3. Everyone's logs are aggregated into a live view of the viz at each dive site! --> The Joy of Participating With so much automation, AI, and tech around us - it's easy to forget how joyful participating in something can be! The Viz App is a chance to get involved with your local viz reports! The Viz App isn't just about dive site reports though. It's chock full of things to make logging your ocean adventures a fun time. --> Water Visibility & Ocean Conditions Water visibility and diving conditions are mysterious and hard to forecast. That's why the Viz App gives real divers the ability to share real reports with each other. Using an app allows everyone to contribute their reports in a standardised way. It makes it possible to show diving conditions in a completely new way. --> Dive Sites 3-Day Trend Lookup the 3-day trend and live conditions. Organised by dive-site & region. See the viz, surge, siltiness, temperature, and more! --> Photo Sharing and Critter Spotting Upload your photos with blazing fast speed. Scroll through your personal logbook to see the highlights of all your best shots from underwater. See the incredible pictures uploaded by fellow divers and snorkellers. "Like" their logs and show thanks for reporting the viz as well as their excellent photos! --> Join the Top Contributors To anyone who has every logged the viz... we all appreciate you! The list of top contributors for each dive site helps recognise those who love sharing the viz with each other. Adding logs, including photos, and tagging critters all earn some contribution points. "Liking" someone's log as well as getting "Likes" also earns some points --> Personal Stats with Incredible detail When back on dry-land, take your day-dreaming to the next level by reliving the highs and lows of your past diving adventures. Track your weekly activity with a unique and inspiring heatmap of your entire year! See the coldest and murkiest dives you've ever toughed out. Remember the days with perfect viz when you spotted every critter. Relish your sense of accomplishment when you look back on the number of dives you've completed in the past month & year. --> Thanks for giving it a go Hope you enjoy the app and find some good viz out there! I’ve been working on an app to make it easier to share the viz with others. The Viz App is a personal passion of mine, and there is no other company or investor involved. Thanks for giving it a try, and PLEASE let me know if you have any suggestions or feedback of any kind! I love diving and snorkelling in Sydney - Gordy's is my goto and Shelly is my fav! When the viz is bad, I go surfing instead!
