Great start, but…
OPEN 1) the documents aren’t stored in a (shared) iCloud folder of choice, which means neither with the same iCloud account on multiple devices, nor with different iCloud accounts over a shared folder, are delivery receipts visible but on the device they were created on. That needlessly complicates things, if one needs to find a receipt, or if one wants to avoid duplication of receipts numbers.
FIXED 2) if one doesn’t enter recipients and delivery parties manually, and instead selects them from the contacts, if the contact is a company, rather than a natural person with first and last name, the company name isn’t used, and instead you find a naked address without the name of the sending/receiving company.
FIXED 3) selecting a custom logo is somewhat troublesome, since typical artwork with a transparent background simply is rendered as a big black square. One first has to open the file in question and render it into a file with no transparency. This is suboptimal, since particularly printers that honor color profiles, often don’t render a white background like transparent (thus only showing the paper), but try to color correct to white according to some profile transformations, which may result in a subtle color hue background being printed where the image file is placed. So support for files with transparent backgrounds would be nice. Of course, one could imagine all sorts of bells and whistles for an app like this, but given the ephemeral use of delivery receipts, the app would be perfectly fine for my uses, if it addresses the above three point, at which point it would be a solid 4.5-stars. A little aesthetic cleanup of the UI, and it’s a 5.
Update: give that two out of three issues were fixed with short order, which massively increased the usefulness of the app, I upped to rating from 3 to 4 stars. Can’t wait for the opportunity to bring it up to five…
Response from developer
Hi, thanks for your feedback! I think, I replied you already per Email a month ago :) Sorry, the Apple notifications didn't work for me all the time. But let me also reply you here, so that also the other users can read my comments. 1. Yes, iCloud synchronisation or some other kind of synchronization is surely very helpful. I realize that and is working on it 2. The issue with Logo is already fixed in the recent versions of the application 3. I released today the next update of the App, that can also import the company name from the address book. We are moving towards 5 starts ;-) Kind regards!
