Bugs in your app? Say buh-bye to your users.

Consumers are unforgiving when it comes to dealing with technological bugs and glitches, and that applies double to technology that deals with their finances.

The majority of finance app users (about 90%, or nine out of ten) will abandon a banking app after noticing bugs, according to a survey released today by independent software testing company QualiTest Group.

The rate and reasons for abandonment vary amongst respondents depending on gender and age, but a common theme was security, the survey of 1,000 participants found—turns out, consumers don’t just look at bugs as minor irritants.

In fact, 62% of respondents viewed banking apps with bugs and glitches as less secure than those without them, according to the survey results.

While most users agreed that they would abandon a glitchy financial app, more men were willing to wait it out than women, with 45% of women agreeing with that statement compared to 36% of men.

Additionally, older users are less forgiving when it comes to glitches than younger users—38% of 18-24 year-olds are “extremely likely” to abandon a buggy app, compared to 44% of 45-54 year-olds.
