## What is MMS Tanks?

Just snap a photo of your sounding table and use Artificial Intelligence to extract the data into your app. The data will stay on your phone as long as you like so the app can be use offline. 

Take depth measurements and get instant calculations for volume, percentage full, and the weight in Tons. Can adjust for temperature and density as needed.  Taking a fuel tally no problem log a tank dip and the app will keep track and add the totals together and give an R.O.B for the tanks.  Import tank data from a printed sounding table in less time than it takes to make a coffee.  Option to manually enter the tank data, if you like to take the time for that kind of thing. And if you do, the app is totally free for use.  

Work on different ships, no problem organize by ship and have as many tanks as you need.  Adjust for various trim tables within each tank.  Works mostly offline. Requires internet connection only when sending scans of the tank sounding tables to the AI agent to read and import data for the app. MMS tanks does not keep any scans or data, at all, anywhere. No ads here. Like having your sounding tables in your pocket at all times.

- Fast data import from a picture.
- Reference tank capacity on the spot.
- Fast calculations with % full indication as you are bunkering.
- keep a log from the last time you sounded that tank.
- No more grease on the tables book. Let it stay on the shelf.

Simple, no fluff, does one thing really well. Built for marine engineers by marine engineers.
