Found this app a while ago and thought I'd give it a go - mostly for the 'chat' style of layout on my phone. Now have it on all devices. Still in chat on my phone, but back to traditional layout on the laptop & desktop... no idea why but just can't get on with the conversation style on the computers. Love that I can do that - set it up differently on different devices but it still syncs seamlessly. And now notes & tasks that integrate and sync! Fab update Spike thank you.

I really liked the look of this, and it seemed to work quite well, but after a short time of using it started to realise that it didn't provide basic functionality (e.g. notifications for emails in folders other than the inbox - key functionality for me that all other mail apps provide). I sent the list of issues to support months ago, which they basically acknowledged, but they don't seem to have any intention to address. To make matters worse, despite never having been told this, the whole thing was basically a free trial. And now it's expired, and become unusable. It tells me that I can carry on using it for personal email (which is all I've ever been using it for) but that my business email can no longer be accessed. I have no idea how it's determining what business email is, but it's obviously doing it wrong, and now I can no longer access my personal mail in it without paying money for a subscription. Even if they addressed all my issues, I wouldn't be paying a subscription for this since none of the functionality is really that much better than other free or one-off payment apps with similar functionality. So bye bye!

I really like the idea of Spike but it's failed me at the first hurdle. The application didn't populated my mail from the past 60 days. Not a problem, beggars can't be choosers, the app is free. However, upon testing sending and receiving new messages, it appears mail sent out from Spike acts as intended. But mail inbound to Spike fails to materialise. I confirmed successful Sent/Received via other mail apps (Outlook & Gmail). So the issue is local to Spike app. On a Samsung Galaxy S22 Ultra.
