While I like the recipes viewed in Yummly, when trying to download the app on my iPhone and then iPad it continuously required me to sign in and then check my email, rinse, repeat. It also didn't synchronise on my iPad and iPhone as all other apps do. I even signed in on the website thinking that might help; no it did not as it made me have to sign in again, check my email again, and so on. Bizarrely complicated so I've deleted all apps
