Ive been using this app since the days of my trusty old Palm units and cannot praise it and the developer enough. Far too many apps, even "numbers ones" eventually disappear into the murk of time, but this beauty endures. And thankfully so. If youre in need of an app even remotely close to the feature set this one offers, then I highly recommend it. You wont be disappointed. Id like to say a huge thank you for keeping the app up to date. Very much appreciated.
