Editors' Notes

There’s no avoiding email—as much as we might wish otherwise—but Spark makes tackling an unruly inbox a whole lot more pleasant. The app is an immediate joy to use, thanks to a painless setup process and a sharp, clean layout. But Spark’s true value comes from its clever interface, flexible customisation and the way it bubbles important emails to the top while filtering out the noise. Inbox intimidation is now a thing of the past.

Mr Edward ,

Very good app overall. A few bugs

Have been using this app since soon after the initial release. Overall it outperforms any other email client I have used for iOS, and is enjoyable to use.
The layout and user interface work well, and updates have progressively improved the app (one recent example was the way emptying the deleted mail went from being a process with a prolonged continually refreshing icon (until complete), to an immediate process with background action from the server.
The standout unique feature from my perspective is the predictive filing system, which automatically shows the most likely folders to choose from when moving items from the inbox to a folder.
There is a bug with calendar events which extend beyond midnight - such as shift work - not displaying correctly (sometimes appear as two separate items in the wrong position on the calendar despite showing the correct time, or just displayed as all day events instead of correctly displaying as a time period). Still - having a combined calendar is useful.

Exactly what I needed

I was very disappointed when Inbox left this world but luckily I found Spark. It’s a very powerful application and I am starting to love it (only used it for a week so far).

It has so many customisation and I absolutely love it. Just one issue re push notification - when I get email notification and hard press it to delete/reply it - it actually try to load the full email which cause delay especially when I just like to delete the email. Some people will like this extended view of the email but some won’t. Perhaps a customisation should be offered in the setting so we can either have simple push notification (with sender, subject etc) or extended push notification with other details.

Overall though, wonderful app - now will be installing on iPad and Mac :)
