Flo'Ology received mixed reviews from music critics.
AllMusic editor Rob Theakston found that ''Flo'Ology'' "rises to the top of the list as one of the best things the group has ever released. The blueprint pretty much stays the same: tasteful, funky neo-soul grooves blended with emotive R&B crooning and spoken word poetry. But there's a much-needed sense of refinement to their style and vocal delivery this time around, a hint of maturity that was lost on their debut and subsequent releases."
The Guardians Caroline Sullivan wrote that the duo conquers "so well that what remains is complete mastery of studio technique but no fabulousness. Their unusual set-up (Ambrosius sings, Stewart raps) keeps things ticking over in a lively way, and Stewart's south-London flow can be a delight [...] But this is solid rather than stunning."
Billboard "offers a soothing experience that freely explores the depths of love." Mark Edwards, writing for
The Times, described the album as "lush, heartwarming music." remarked: With the presence of Common on "SupaStar," and production from Scott Storch and Raphael Saadiq, this is an album pitched at the American neo-soul market. Once you accept that, however, you can enjoy the smooth soul of "Let Me In" and "My Apology," and perhaps even the ballad Sometimes "Make Me Smile," where any soppiness is outweighed by Ambrosius's spine-tingling performance."
PopMatters critic Stefan Braidwood found that "on the whole then, there seem to be a fair few reasons to be into Floetry, but unfortunately the songs on this new album are not amongst that number. This [...] may be because the endemic "beats and vibes over songs" effect that’s consuming this generation of artists has also, objectively, struck here as well." ==Commercial performance==
