The game's main gameplay is in "Live" mode, in which players tap on the five buttons at the bottom of the screen at the proper time to receive a score. A combo score multiplier is given for maintaining a chain of consecutive hits without missing notes. Concert footage of the songs are played in the background. Scores are then classified into C, B, A, S, SS, or SSS rank, with C being lowest and SSS being highest. Songs are divided into three difficulties: "Normal", "Pro", and "Master"; a fourth "Pro+" is available for select songs. A "Live" difficulty level is provided just to watch the concert footage. There are a total of 57 songs included. Songs span all Sakurazaka46 and Keyakizaka46 singles, Hiragana Keyakizaka46's album Hashiridasu Shunkan, and 3 of Hinatazaka46's single "Kyun", "Do Re Mi Sol La Si Do" & "Konna ni Suki ni Natchatte Ii no?". "Dare no Koto o Ichiban Aishiteru?" from AKB48's Bokutachi wa, Ano Hi no Yoake o Shitteiru was added into the game as part of Keyakizaka46's 3rd Year Anniversary Live.

Uni's On Air utilizes a gacha system known as "photography" to acquire cards known as "scenes" that feature a member of Sakurazaka46 or Hinatazaka46. Cards are classified into five colors: red, blue, green, yellow, or purple; they are also classified into three rarities: R, SR, and SSR. These cards can then be built into five-unit teams; using the same color card as the song yields a higher score. Cards may be leveled up in two ways. In "level lesson", players may increase the card's level through "lesson points". In "talent blossoming", players upgrade specific attributes in a hierarchical order. Talent blossoming also unlocks other content, including more pictures, interview footage, voice recordings, and costumes.

The game also features an "office", where players can talk to members, decorate the rooms, and offer "catering" in exchange for in-game currency. "Dramas" are also included, where players can watch fictional stories featuring the members.
