Last year, it sold 48 million iPhones, with revenue of $54.1 billion and net profit of $13.1 billion.
Apple said it also sold 26 million iPads during the quarter, topping its previous record of 22.9 million sold in the year-earlier quarter, when it also sold 47.8 million iPhones. Mac sales were up to 4.8 million from 4.1 million in the first quarter of fiscal 2013.
The company's gross margins slipped to 37.9 percent from 38.6 percent in the comparable quarter a year ago. Apple said that 63 percent of its revenue came from international sales.
Earnings per share, at $14.50, were in line with analysts' estimates that averaged $14.09 per share. Apple will pay a cash dividend of $3.05 per share on Feb. 13.
For the current, second fiscal quarter, Apple is forecasting revenue between $42 billion and $44 billion, and gross margins between 37 and 38 percent.
The flat profits from last year, combined with the relatively weak guidance, sent the stock down 8% after hours.
