Suggested upgrade...
Good program! I am glad somebody has developed this for iPhone/iPod Touch! It would be nice to see a graphical representation of tide heights (on a chart) as opposed to just the high and low times. It would also be useful to be able to see information for a few months in advance as this can be a very handy planning tool for boat maintenance (determining the optimal time to take the boats out of the water, etc.). These two features would have bumped the rating from 4 to 5... I look forward to seeing an updated version - keep up the good work!
