★★★★☆ Portrait view only
I’m thankful for the EML viewer at a reasonable price, but it cuts off the page in landscape mode on iPhone and iPad without the ability to move or zoom. I use my iPad like a laptop with an attached Bluetooth keyboard, so it’s inconvenient …
★★★★★ Works as explained!
Exactly what I need for opening .EML files on the go!…
Top negative
★☆☆☆☆ Does not work
I archive work emails in EML format from Thunderbird. This app only turns the screen white and does not open the EML file. Waste of 2$ enjoy it……
★★☆☆☆ Nonsense.
Decoded header of forwarded message. Nothing else.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
