    While Spark is very appealing aesthetically, I would not recommend using if you wish to keep your email contents private.

Hello guys! Thank you for warm words and support. We'be been working on this for the last 18 months. I hope Spark will be on your home screen. Also, please note that this is just version 1.0 and we have a long list of things to add and improve. Mac + iPad are also coming a bit later.

@denzhadanov Congrats to you and the team at Readdle for shipping Spark. What made you guys want to go after the email space and what's your unique take on it? Also curious to know what the business model is.

@denzhadanov I'm really glad you mention a Mac version is in the works. There are so many options for mac but nothing that really works well for me. This looks great!

@denzhadanov From Federico's review, it sounds as though Spark doesn't use send your email credentials to a cloud backend, instead doing everything on-device – is that right? I know for a lot of companies, cloud-based & IMAP is a bit of a no-go, so if everything is done locally, I'd emphasize that somewhere – seems like it's a USP.

@denzhadanov great product. I keep trying out new email clients with hopes that one will be attractive enough for me to ditch Apple mail. I'm hoping this could do it as Mailtime could not. PS: you misspelled "personalize" on the tutorial.

@denzhadanov I am beyond impressed by Spark. It is the first mail app since Mailbox or Sparrow that has actually stayed on my homescreen. Looking forward to future releases!

@denzhadanov You guys should mention the snooze feature on your landing page. It's the first thing I looked for on your site and couldn't find it until I dug into the Personalization page.

@davemorin Cheers Dave. We're about to ship the iPad version. Let me know if you would like the beta. Also, we have a much bigger vision of where Spark should go. Would love to tell you and hear your feedback.

@denzhadanov You guys still rocking. Just waiting for the addition of Gmail Categories what would make life far more easier for people who receives lots of newsletters as me.

Installing now. Quick question, how do you guys make money on it if I don't have to buy it?

@robjama the review is incredibly in-depth! It's super-duper detailed and long... in true @viticci style :)

@robjama Spark for Mac has just been released by Readdle.

Very nice, it has everything I need but lacks support for html signature :/
Andy Beaumont@drcongo · CTO
This just instantly replaced Mailbox in my iPhone's dock. It's fantastic.
