Fireboy described his mindset during the creation of Apollo as being in "god-mode," referencing the album's title, which is named after the Greek god of music and poetry.

Motolani Alake from Pulse Nigeria described Apollo as a significant step in Fireboy DML's growth, calling it more sonically and topically diverse than Laughter, Tears, and Goosebumps.

[10] Jerry Chiemeke of Afrocritik praised Apollo for its strong storytelling but noted that the production "falls short" compared to Fireboy DML's debut.

The album follows the celebrated Laughter, Tears & Goosebumps and continues to showcase Fireboy's ability to blend Afropop with singer-songwriter sensibilities.

[12] Emmanuel Esomnofu, writing for NotJustOk, praises Fireboy DML's Apollo as a strong sophomore effort, though it faces some issues with track listing and transitions.

Esomnofu notes, "Fireboy DML doesn't succumb to the slump associated with second albums" and views Apollo as a testament to his timeless potential.

[13] Ivie Ani, writing for Pitchfork, describes Fireboy DML's Apollo as a smooth blend of R&B, Afrobeats, and pop, marking the peak of his "Afro-life" sound.

Fireboy excels at capturing everyday life and romance, creating "quiet after the storm" vibes rather than overtly grand statements.
