Readdle is a Ukrainian software development company. It produces a range of productivity software, including calendar, email, and document management applications, primarily built for the Apple ecosystem available through the App Store.[5] As of 2024, the company's software has garnered more than 200 million downloads worldwide.[6]

History

Readdle was founded in 2007, in Odesa, Ukraine, by former college roommates Igor Zhadanov, Alex Tyagulsky, Andrian Budantsov, and Dmitry Protserov.[7] The company is considered a global pioneer in iOS software development, having produced its inaugural web-based application to address file management on the iPhone prior to the launch of Apple's App Store.[8]

In July 2014, the company opened its first physical office outside of Odessa in San Francisco, California, a major American technology hub.[8]

Following the 2014 Russian invasion of Ukraine, Readdle took steps to protect the viability of its operations, such as moving its data online, which has allowed the company to continue to operate throughout the conflict.[8] Despite regular attacks on Odesa by Russian forces, Readdle's maintains its to headquarter in its founding-city.[9]

Documents (previously ReaddleDocs) is a file management application.[11] 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.[12] 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.[13] 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.[14]

Spark is an email application for Windows, iOS, macOS, and Android devices.[20][21][22][23][24] Lifehacker wrote that Spark was the best alternative for Mailbox users when that service went offline.[25] It was released on April 2, 2019, and was Readdle's first app released on Android.[26]

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.[27] 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.[28]
