Documents (previously ReaddleDocs) is a file management application.[9] The app was Readdle's first product, and was developed because co-founders Alex Tyagulsky and Andrian Budantsov wished to be able to read books on their iPhones.[7] It was initially released as a Safari-based web service in 2007.[10] Later, Apple asked Readdle to submit the app (then called ReaddleDocs) to become one of the 500 apps available on the App Store when it launched on July 10, 2008.[11] After Wall Street Journal writer Walt Mossberg endorsed the app, sales increased ninefold, netting the company $500–1000 a week.[7] In 2013, the app rebranded as Documents.[12]

Spark is an email application for Windows, iOS, macOS, and Android devices.[18][19][20][21][22] Lifehacker wrote that Spark was the best alternative for Mailbox users when that service went offline.[23] It was released on April 2, 2019, and was Readdle's first app released on Android.[24]

Spark +AI

In 2023, Spark introduced artificial intelligence features for premium users. Dubbed 'Spark +AI', the service first launched by utilising Microsoft Azure OpenAI software to draft, rewrite, and contour emails on behalf of users.[25] In 2024, Spark +AI continued to enhance its service by rolling out a new feature which supports AI content generation in the style of the end-user, allowing for more human-like/natural email construction.[26]
