The Hiden Risephone (飛電ライズフォン Hiden Raizufon) is Kamen Rider Zero-One's personal smartphone that can also summon the Rise Hopper Rider Machine from the satellite Zea after scanning it on the Authoriser of the Hiden Zero-One Driver.
A mass-produced variant without the motorcycle functionality is used by the general populace.
Originally owning the silver mass-produced version of the Risephone, Aruto Hiden is later given the "President-exclusive" Hiden Risephone after taking over as president of Hiden Intelligence and taking up the mantle of Kamen Rider Zero-One.
- ID: An ID app. It generates hard light silhouette (hologram) of Identification Cards flashing out of the Risephone.
- Mail: An Email app. Usually used to read messages sent to the phone and announces a message has come with the retro phrase "Aruto! You Got Mail!".
- Bike: An app that is used to call for Zero-One's personal Rider Machine from the satellite Zea. If pressed on the Rise Hopper in its Risephone mode, it turns into a bike.
- GPS: An app in the mass-production versions that is located on where the Bike App is saved on the President's Exclusive Risephone.

- This is the second time a smartphone is connected to the Rider Machine, the first instance being the Build Phone and its ability to transform into the Machine Builder.
- In addition, the DX Hiden Risephone reuses the bike engine and bike attack noises from the DX Build Phone/Machine Builder.
- Unlike the Build Phone, the Hiden Risephone and Rise Hopper are two separate items, with the Risephone's bike app sending a signal for the Rise Hopper to be beamed to the user's location.
