Great app, could use widgets

Honestly one of the best mail apps I’ve ever used so I have no interest in using a third party app to access my Fastmail. the placement of buttons is really friendly and discourages you from having to stretch to the top of the screen. Touch ID protection by default is nice, and it loads quickly enough that’s not a problem.

The bad: there are a few features in settings that it LOOKS like you can use, but actually they require desktop. And unlike some other mail/calendar combo apps, there are no iOS 13 home screen widget available. Would like to see that happen.

Great redesign and service

I’m a happy Fastmail user, and have used Gmail, Office365, Yahoo Mail, and a self-hosted solution in the past to handle my email. Out of all the options, Fastmail made the most sense, even after paying their reasonable fees. Haven’t had more than maybe a hour worth of downtime, and their support is actually useful. Their product is great and is not only super fast, but also secure. I’ve done a great deal of research into their backend/operations, and they are dedicated to security in a multitude of ways, and interested in the “next wave” of technologies for email. The only suggestion I have is for integration for iOS sharing (ex: If I want to share a PDF I first have to save to iCloud then upload that document from iCloud manually into email, whereas with Gmail you can use the sharing extension with one tap).

Edit: They added iOS Sharing!!! Yay!!!

Only last suggestion: add dark mode for iOS 13??

Great service, wish the app was native

Opened the app this morning to find they’re forcing me to use their preferred font instead of the system font I had selected in the previous version. I looked through the settings and it seems they’ve taken that option away. The dark mode also is custom, and isn’t True Black but instead an annoying very dark gray which makes for a brighter screen at night than is possible if they used the native UI. This app is what you get when web developers don’t actually like the platform they’re developing on, or think they can do better than the OS - it makes for a jarring experience with the rest of the phone.

They’ve also increased the amount of white space, and made the font size of the folder you’re currently viewing much larger, creating more wasted space and reducing the number of messages visible on the screen. Why not put it between the menu bar control and the search icon? I love FastMail’s service but am growing to hate the app.
