Iqango Log did't save after finishing and losing connection

I did record some data and finished it with Iqan go on iphone, so walk away from the unit to save. But with walking away i losing the connection. The app did stay in the save page so i tried to save but it didn’t save the file anymore. 

Can they do something that you are always able to save the file even if you lose the connection.

And you can download logs and record’s but you can’t open them on your phone, you still needs a pc to open.

Will be perfect if you can open the simple data on your phone. Downloaded logs and records made by phone(measure files), settings files. Csv files. 

All made by the app but not able to open.
