Ultimate Comics: Spider-Man #1, written by Brian Michael Bendis with art from Sara Pichelli, launched this week as a day-and-date digital release.
"I am completely humbled by the support and success of Mr Miles Morales in both print and digital," Bendis said. "Nothing frustrates an author more than his work not being able to get into the hands of the people that want it, and now with the Marvel Comics app we can!
"We've been pushing to make Ultimate Comics: Spider-Man our top release to date, and the results we've seen both here and in print certainly show us that we're heading in the right direction," Marvel senior vice-president of sales David Gabriel added. "We've been doing the day-and-date comics for about a year now since the launch of Ultimate Comics Thor #1, and each subsequent release has not only seen increased sales within the app, but we've also seen a great trend in which the print comic reorders increase exponentially."
The title's first issue introduced readers to Miles Morales, a half-black, half-Hispanic teenager who takes on the mantle of Spider-Man following Peter Parker's untimely death.
Bendis recently said he was 'surprised' by the amount of controversy Morales's introduction had caused.
Ultimate Comics: Spider-Man #2 will be released on September 28.
