How to contact???

1. In pro, large chart, zoomed map can’t be scrolled all the way to the bottom. Example: Orion map, zoomed all the way out, clips off Sirius & bottom axis.
2. Email button, under info, does not work.
3. In contact us form code image not loaded & reload does nothing.

Apple phone app doesn’t work

The app itself is handy. I sprung for the in- app purchase and like the more detailed star charts. When opened on the watch, no data is displayed

Double dips on the unlock feature

This app insists on you paying $1.99 for each iOS device that you want to see the large charts. This is the first time I’ve encountered this issue on any app. I reported this as well but the developer hasn’t responded. Please fix.

Sun Moon Data Incorrect

Sun Moon Data Incorrect - Data is incorrect as it does not acknowledge Standard time. Also, Civil Dusk precedes Astronomical Dusk.

Large maps terrible

I bought the upgrade version to get the larger charts for each constellation. Example: Virgo constellation on large chart is in the upper right corner of the large chart and parts of it are not viewable. There are other examples. I bought it because Wil Tirion is the cartographer but I’m disappointed with these charts as presented. The constellation chosen should be in the center of the large charts. Buyer beware. Sorry developer, nice idea but issues with this app. Maybe update the large charts to put the constellations in the center of the page.

Response from developer

Hi Solar, that's weird. Have you tried re-installing the app? Does that fix the problem? If not please let me know at post@surfcheck.info, so I can fix it in the next update.
