User reviews

Useless

Can’t use it - whenever I open it it just keeps crashing. Not worth fiddling with.

Do not buy this app

It worked for a few days and then has not worked since. Deleted it, re-installed it. Switched phone off, re started and nothing happens other than it opens then immediately closes. Wanted to support this as it’s locally built but sorry if this was a product I’d be taking it back to where it came from and asking for a refund.

Response from developer

Please contact us so we may find a solution for you. It could be as simple as freeing up some memory on your device.

Really useful, but you need to subscribe

Forget the one-star idiot, if you don’t subscribe you don’t have new data, once you subscribe it’s great.

Old 2018 data beware

Don’t rely on this as it is inaccurate and shows todays date and time perfectly but for 2018 and with 2018 data. So misleads you into the wrong information

Response from developer

The app is free to download and try, using 2019 data. However if you subscribe, it will display 2020 ( or current year ) data.

Top app. Very useful.

Saves a lot of time working out tidal hours.
