Great email app

I started to use Spark a few months ago on both my iPhone and MacBook. I am impressed with the application on both platforms, it looks great, smart inbox is truly smart, and connecting well known to-do apps and task managers to Spark is a fantastic idea. I am not a very heavy user, the only problem I had is that, that badges disappear from the app icon when I close the app on my Mac. This started with version 2.0. Since this issue is very minor I am going to give 5 stars to Spark, well done Readdle, keep up the good work!

Great app, fastest email consumption - crystal to be polished

Overall this email client provides a fully different experience, allowing you to work much more effectively than with built-in clients.

Feature-wise it includes really nice things with signature recognition, timed emails, smart inbox that works effectively.

The only downside is that the application could use a serious bugfixing round as it's surprisingly easy to make it crash. Data has not been lost yet, the drafts save the game, but I really do hope the developers have Crashlytics or something similar enabled, so that they can eliminate the most obvious crashes that are not caused by edge cases and really strange user behavior. In current status it can be a bit annoying if it crashes on you and cannibalizes itself in the eyes of the super-busy person who does not have the time to reopen the app and continue where he/she left off.

Closer to perfect than any other mail apps

I used Airmail for 1 year, but it had so much bugs and made my business mail so painful to use (constant blockings from server provider...ecc..) that I decided to switch. Spark has a bit less functions but I'm really sattisfied by the fact that it did not make any bugs at all. Now I'm "freed" from stress when I use that app, on Mac, on iPad and on iPhone as well. All the three devices perform really well...and if you take in acount that it is
Good job guys!
