Blockchain, an iOS app allowing users to manage transactions using the Bitcoin online currency, has been reinstated to the App Store.

The app, which is connected to an online wallet service also operated by Blockchain, was pulled from Apple’s portal in February, two years after its launch, with the iPhone maker citing “unresolved issues”.

It was the latest move that suggested the iPhone maker was opposed to Bitcoin-related products. It previously removed BitPak, Bitcoin Express and Coinbase, and in December 2013 forced messaging app Gliph to remove Bitcoin functionality.

The uncertain legal status of Bitcoin is likely to have been behind Apple’s wariness.

The company issued guidelines for virtual currencies at its World Wide Developers Conference in June, stating that it would accept apps that involved a cryptocurrency as long as they complied with applicable state and federal laws.

Blockchain subsequently said it would resubmit a new version, with CEO Nicolas Cary telling WSJ via email that Apple was “very responsive” during the submission and approval process.

Cary added that the move “really signals Apple’s commitment to supporting developers on Bitcoin related projects – it’s very encouraging”.

Back in February, Blockchain said there was “no indication of any problems and no opportunity to redress any issues” when Apple removed its app.

At that point it had racked up 120,000 App Store downloads. Cary expects a surge of downloads now that the app has been reinstated, due to the increased use of Bitcoin since its removal.

Blockchain has just unveiled a new version of its app for Android, including a feature that allows users to search retailers that accept Bitcoin. The company’s online wallet service currently has more than two million users.
