The app looks laggy, choppy and overall not too good. It's hard to find some features, and the intro is also really laggy. The dark mode is too dark, please add a Dark and a Black mode. Also CC's show all names, it's terrifying. But, the app still has some cool functions I'm gonna keep using the desktop version but I'll pass on this one till it becomes usable.

(UPDATED 6-16-25) SPIKE IS STILL THE G.O.A.T!!! Spike is still the best! (10-14-22) Spike is changing the game on email. At first I couldn't be bothered with their innovations, but when they finally solved that one problem I had with other email clients - and then crushed the competition on every other part of an email client that I didn't realize I was in need of - I've been a hugely grateful supporter ever since.

after sometime it asked me to log in to my 10 email accounts again. I have to put login and email server settings for every account again on every mobile or computer I use, which costs me too much time. after this billing cycle I'm done with spike.
