I struggled a bit to import the data into the iOS version. I had saved the data, not emailed it. So I needed to open the file, then click the export button, then choose "..." in Dropbox (where I saved it), then choose Export, then choose the App Store icon which says "Open in" below it. Then select the Pool Math icon which says "Copy to Pool Math" below it. Could be I'm just a little slow too! I thought there would be an Import button in Pool Math so I was thinking backwards of how it's designed. And since I didn't email the file, it didn't immediately have the Pool Math icon listed when opening it, I had to choose Export first then find it.
But all is good and I'm live.
To see the data I did have to close the app then re-open. Voila!
Thanks TFP!!!
I just spent 10 minutes trying to figure out how to import my backup from dropbox on the iphone. Wish I had seen your post sooner.
To summarize: open the backup file in dropbox, tap 3 dots in the upper right hand corner, export, open in, copy to pool math
