The show debuted with 13.7 points, on par with previous Morena shows and leading its timeslot. However, it began struggling when "Patito Feo" made its debut on Canal 13. The Ideas del Sur production was a huge smash and, for the first time, Morena didn't have the leading kids show in the country. "Patito Feo" products were also outselling "Casi Ángeles" and, in April, "Patito" was winning with a vantage of over 2 points in rating, forcing the show to change its timeslot to 5:30p.m. After the change, "Casi Ángeles" started to considerably increase its ratings and returned to its original slot, facing "Patito" once again. This time, ratings were stable and the show achieved its biggest numbers with the season finale which achieved 16 points and easily beat the competitor. At the end of the year, both shows had similar numbers: "Patito Feo" averaged 12.6 points while "Casi Ángeles" averaged 12 points. Commercially, the show was still a success with over 50 licensed products and a Platinum-selling album. The musical at Teatro Gran Rex attracted over 140,000 people. Even so, commercially, the show was outshone by "Patito".
