Why:

Statistics

13. www.eliftech.com
● More than 13,000 developers shared their story
● Two years ago, 20% of developers surveyed were building exclusively with native tools
instead of hybrid. In the next two years, that number is only 2.9% - a nearly 7x decrease.
Similarly, the number of hybrid-built apps is growing as a share of overall app development.
In the next two years, 32.7% of developers surveyed expect to completely abandon native
development in favor of hybrid.
