This app could be great and I really hope things change. I paid 6.99 to upgrade to Pro for Dropbox sync, but there has been no sync/backup functionality after close to a week of connecting my Dropbox account. I've tried everything to get this to work. Experimenting with exporting invoices, etc. Nothing worked. I tried emailing customer support (listed on their product description) and got an automatic reply saying that their email account is full. I also noticed it's been more than a year since their last update. I misread the most recent version as being from 2016 instead of 2015. Developers, please do something about this, especially for people who've trusted that your Pro version would yield some sort of benefit (backups) and have paid the extra money to get that basic functionality. I paid for an upgrade that was essentially like the free version and have found no way to get any customer support. In addition to these problems with the upgrade to Pro, I'm also frustrated (like others on here) with how overtime is illogically reported. With such a high price to get Dropbox functionality that eventually didn't work, I really regret this purchase. I'm moving to a different app and seeing if I can somehow get my money back if nothing changes soon. Update 10/8/17 (changed from 1 to 3 star review) Syncing works, but I’m having trouble removing a photo from my Profile so it doesn’t show up on my invoices. I can only replace it with another photo, but I no longer want a photo since having one increases the size of the invoice PDF. Speaking of PDFs, I would like to see improved exporting options. Right now, I only have email and print. It takes forever to receive the email with the invoice and I send all my resumes digitally so I would prefer if I had the same export options (export as PDF, text, csv, etc. to iCloud, Dropbox, Google Drive, Gmail, etc.) that several modernized iOS apps have. Finally, I can’t change the Invoice Date like I used to. I would like that function back. Also, since I upgraded the free version to Pro from within the app, I’m fearful that I’m not getting the same exact app as Hours Keeper Pro because of all these lingering issues. Just a customer fear I have. Please make these slight, but significant improvements. I could see this easily being a 5-star app!
