Design
Standard Apple album and single labels displayed a bright green Granny Smith apple on the A-side, while the flipside displayed the cross section of the apple. The bright green apple returned for Beatles CDs releases in the 1990s, following initial CD releases on Parlophone. However, on the US issue of the Beatles' Let It Be album, the Granny Smith apple was red. The reason was that in the United States that album, being the soundtrack to the movie of the same name, was, for contractual reasons, being manufactured and distributed by United Artists Records and not Capitol Records, so the red apple was used to mark the difference. The red apple also appeared on the back cover, and on the 2009 remastered edition back cover. In the late 70s, Capitol's parent company EMI later purchased United Artists Records and Capitol gained the American rights to the Let It Be soundtrack album (along with the America rights to another, earlier, UA Beatles movie soundtrack LP, 1964's A Hard Day's Night). Aside from the red apple, there have been other examples where the apple has been changed, notably on Harrison's Extra Texture (Read All About It), where it is eaten away apple core (this was intended to be a joke because it was released at a time when Apple Records was beginning to fold). And there were some more: in 1970 for Harrison's All Things Must Pass triple album, two records that have orange apples and one with an Apple Jam jar; in 1970 for Lennon's John Lennon/Plastic Ono Band and Yoko Ono's Yoko Ono/Plastic Ono Band black and white apple labels; in 1972 for Ringo Starr's "Back Off Boogaloo" blue apples; in 1975 for Starr's Blast from Your Past red apples. Also other type of apples were used: in 1971 for Lennon's Imagine and Ono's Fly, in 1973 for Ono's Approximately Infinite Universe and the singles that were released from those three albums.

Zapple Records
Zapple Records, an Apple Records subsidiary run by Barry Miles, a friend and ultimately biographer of McCartney, was intended as an outlet for the release of spoken word and avant garde records. It was active from October 1968 until June 1969, and only two albums were released on the label, one by Lennon and Ono (Unfinished Music No.2: Life with the Lions) and one by Harrison (Electronic Sound). An album of readings by Richard Brautigan was planned for release as Zapple 3, and acetate disc copies were cut, but, said Miles, "The Zapple label was folded by Klein before the record could be released. The first two Zapple records did come out. We just didn't have  ready in time before Klein closed it down. None of the Beatles ever heard it."

Brautigan's record was eventually released as Listening to Richard Brautigan on Harvest Records, a subsidiary of Apple distributor EMI, in the US only. According to Miles, a spoken word album by Lawrence Ferlinghetti, which had been recorded and edited, would have been Zapple 4, and a spoken word album by Michael McClure had also been recorded. A planned Zapple release of a UK appearance by comedian Lenny Bruce was never completed. An early 1969 press release also named Pablo Casals as an expected guest on the label. Zapple was shut down in June 1969 by Klein, apparently with the backing of Lennon.

Artists who signed with Apple Records
Badfinger (originally known as the Iveys) - Signed to Apple after several demo tapes were brought in by Mal Evans, after getting approval from McCartney, Harrison and Lennon.

EMI refused to handle it due to its intentionally vulgar double entendre ("Fuh king"), but Apple manufactured a small number of copies in-house which were made available to the public. The song itself appears on the 2010 compilation, Come and Get It: The Best of Apple Records.

Elastic Oz Band - A one-off single, "God Save Us", was written and produced by John Lennon and Yoko Ono to raise money for a legal battle involving Oz magazine. The A-side of the single was sung by Bill Elliot, later of George Harrison's Dark Horse Records signing Splinter.

Also released were the soundtracks to Come Together and El Topo (in the US), the onetime Philles Records compilation Phil Spector's Christmas Album and the multi-artist The Concert for Bangla Desh. Cassette and 8-track tape versions of Bangla Desh were marketed by Columbia Records, in a deal that permitted the inclusion of Bob Dylan, a Columbia artist, on the album.

Artists who went on to have considerable success in the pop and rock world (though in some cases, for their post-Apple work) include Badfinger (originally known as the Iveys), James Taylor, Mary Hopkin, Hot Chocolate, Yoko Ono and Billy Preston.

Artists who were to appear on the label, but did not make it, include:
McGough and McGear (who was also McCartney's brother), whose self-titled album was due to be released on Apple, but it was released on Parlophone Records, to which both were signed, as members of The Scaffold;

Grapefruit, whose single "Dear Delilah" was issued on RCA Records with Apple Records publishing credit;

Focal Point, a Liverpool band who were going to be managed by Brian Epstein before he died, were signed to Apple after chasing Paul McCartney around Hyde Park.

Delaney and Bonnie's Accept No Substitute album was originally meant to be released on Apple in 1969; it was first released commercially on Elektra Records the same year. In England, copies of the LP were pressed before Apple realized the band was already contracted to Elektra. No album covers were ever printed and the disc is now a high-value Apple collectible.

Mortimer were a folk-based three-piece, notable for a recording of the Beatles' "Two Of Us". It was planned for release as an Apple single in 1969 (before the Beatles' version was issued) under the title "On Our Way Home", but the release was cancelled.

Slow Dog (Wheels) who were a Cambridge based rock band headed up by Scottish singer/guitarist Dave Kelly. They were the winners of the Apple Records sponsored national talent contest early 1969, organised by Apple A & R head Peter Asher prior to his departure for the US. The winner of the talent contest was promised a record contract with Apple Records, but the band only recorded demo tracks, due to Asher's departure. However, on the recommendation from Beatles' roadie Mal Evans, Warner Brothers Records in London, headed up by Ian Ralfini, signed Slow Dog to a record contract, changing their name to Wheels.
