Subscriptions

How do I create a subscription for the current year?? I’ve been going around in circles trying to get the latest DB update! On the phone app menu I click on the apps option with the cart widget, get taken to the list of apps where I cannot see an option to subscribe only open. Which then takes me to the app on my phone then ditto

Response from developer

To create a subscription, tap on settings, then the shopping trolly icon (top right)

Dissapointing

Each set of tides needs another subscription and the Set and Cts tools have to be purchased separately purchased for each set. Also the vessels position is not shown on the chart although that option is selected on loading. These disappointments spoil what could have been very useful software.

Excellent if you subscribe

Forget the one-star idiot, he didn’t subscribe so of course it was old data.

Old 2018 data

Year old inaccurate data from 2018 beware

Response from developer

The app is free to download and try using 2019 data, subscribe and you can use with 2020 ( or current year ) data.
