I tested Outd Log on my iphone 5S, ipad 4 and Lenovo Tab3/7 running android OS. on each platform the app seemed to look and behave the same. It reliably let me record new contacts and they were included in the output file.
I found that on the Android tablet and on the Ipad, the logging screen layout was ok, but on the iphone 5S (a smaller screen) there was some wraparound of captions, one was wrapping and the second line appeared below the data field which was a bit disconcerting. Some of the dropdown functions were formatted slightly unusually on the iphone 5S - a later model phone with a larger screen (in pixels) may well circumvent that.
There is no provision for posting or viewing alerts or for cloning existing spots (such as when you want to respot yourself on a new band or mode after a change). The app caters for SOTA and GMA. The log file is output in either CSV or ADIF format, presumably it is intended that you import the log into the station log and then extract the contacts in a relevant format for SOTA or GMA. The file can be saved on the device or onto a cloud file service, or emailed to a nominated address. In tests, I emailed it to myself.
I was asked whether I would change to this app from VK PortaLog; my answer is no, because VK Portalog has facilities for both SOTA and WWFF awards, interacting with both Sotawatch and with the Australian website for wwff spotting, parksnpeaks.org. Its integration with the sites is very good and it outputs all file formats required for direct submission to those two awards in addition to an adif file containing all details for input to your station log. The swipe left and right options are very useful in terms of usability and fit naturally with native apps for the platform, rather than being called up by menu options.
in summary, I found OutdLog worked quite effectively and presented a common format to each platform, which is rather unique. Certainly worth trying if you are looking for a portable logging solution for SOTA or GMA.
I hope this is useful to someone.
