Sling TV's cloud DVR service is now available for iPhone and iPad. The streaming service's DVR "First Look" option costs an additional $5 per month and gives you 50 hours of DVR storage. The iOS devices now join the growing list of DVR-supported systems, which includes AirTV players, Amazon Fire TVs and tablets, Android TVs and mobile devices, Apple TVs, Roku streaming players and TVs, Xbox consoles and Windows 10 devices. Sling TV began beta testing its cloud DVR option last year and started rolling it out to users in April. This month, the feature got an upgrade with an added option to protect recorded shows from being deleted.
