What about an online note taking memory, perhaps call it a XXX Golf Caddy, (where XXX is a brand name), basically it could collate all your shots on every course, distance, wind, green speed (if applicable) club used, etc, basically all those notes so many players laboriously write down, and then have to search through to find. Ideally it would be a part of the memory on your profile, but it could be a separate excel spreadsheet. I'm sure a few of the more lazy players (ahem cough cough) would pay for such a service.
Just an idea, tbh I was thinking of a iron mate along the lines of the putter mate, but even my programming skills realised that was a big ask.
