The findings, which were derived from data submitted via the app or through email, claimed that more than 40 percent of couples are spending 20-plus hours together more per week than usual, thanks to self-quarantine measures. During the extra time together, 51 percent of engaged couples and 66 percent of married couples have reported learning something new about their partners' snacking habits, future goals or how they handle stress.

Engaged couples, of which 86 percent polled said they were quarantining together, have reported spending more time binge-watching TV (71 percent), cooking (53 percent) and working out together (40 percent). One-third of engaged couples also reported having more sex than before the pandemic, The Knot claims.

Married couples have instead reported spending more time on home improvement projects (48 percent), watching TV (46 percent) and baking together (42 percent).

Despite the increased time together, only 18 percent reported being happy with how they communicate with their significant other.

"This is a unique time for couples. Social restrictions and financial uncertainty are two of the top contributors to increased stress, anxiety and conflict among individuals and their relationships," said Steven Dziedzic, founder of Lasting, in response to the survey results.

According to the survey, the pandemic has actually had a positive effect on engaged couples, with 6 in 10 couples claiming that their relationship has strengthened since sheltering in place. About 64 percent of engaged couples said the positive impact comes from finding new ways to spend quality time together while being stuck inside, as well as being forced to discuss challenging topics such as finances and unemployment, as well as preparing for potential illness.
