Surveyor Luis C.

Let me start by saying that your apps are indispensable to the modern navigator.  I am a US Merchant Mariner and use several of your apps on a daily basis a countless number of times.  Thank you for the great work you do.
Best Regards,

USCG Licensed Third Mate Victor D.

Great apps can help a lot on a routine work on board. All details are included regarding wind up to plotting them with photos of Sea condition from The mariners Handbook. Instead of cross referencing your observation into other pubs. Here you have all in one with a tap of fingertips.

Paolo D.

I am very thankful on the app. that you made. It helps a lot to me as navigator... You truly nailed it, amazing mobile app.

Looking forward you will make another app for the navigator or officer onboard...🤗

Best wishes and more success! 

Respectfully yours,

Ranie Q.
