Downloading and working with training materials works fine so far.
Regarding dive logs: We have Mares computers with bluelink device - so far, so good. Others are not supported yet, however.
Some remarks on the iOS app and the log functionality: we're beginners on diving and yes, we do use it and its mainly to keep an overview over the logged dives and the related "achievements" in the SSI experience ladder. For logging purposes, however, there are some features/topics which seem to be a bit buggy or even would deserve serious improvement:
- add dive sites via map: its not possible to switch to a satellite view when adding personal dive sites and normal vector map details are of course not existing in ocean or reef environment. Please add that option.
- is there an option (web or app) to correct dive site locations? Many in your database are totally messed up and displayed far away from their real locations, that's why everyone is forced to create his own.
- although displayed on dive computer (Mares Quattro), some params are not imported like for instance temperatures or average depth, pls add that option.
- when importing several dives at the end of a dive day many repeating parameters and equipment info need to be filled one-by-one manually. As most of them are naturally the same: could you add a pre-filling of these fields with the values entered before?
- diving internationally: often pressure is displayed on rental equipment in either metric or imperial units, could you integrate a converter or a dropbox to choose unit and convert automatically?
- could you add drop-down menus for the most common tank types being used (Alu, steel, some standard sizes, ...) and take over the values for air consumption algorithm?
- GUI for profile view is extremely poor and for example on ipad mini 4 not usable at all. Could you add at least properly working zoom/pan options?
- Could you add options to import and exports dives "out of the SSI world"?
- When sharing dives with a buddy only a very few parameters are transferred. Could you enhance this or offer a menu to configure it?
- sea level/altitude can not be added (important for mountain diving!)
- some parameters do only have limited options to choose from (for example type of water, type of entry, ...) Could you add at least a free text option to create owns?
- how can dives be confirmed if the base is not a SSI-one and does not have a QR-code available?
All in all with this situation therefore only 2 stars.
