Cant use on multiple devices

If you want this app on more than one device & you create a routine on one device - forget about getting it on the other device. AirDrop, messaging & all the other options dont work. It looks like airdrop should work cause it sends & receives but nothing shows up in the app so basically it didnt get there. Why cant they just sync it through the cloud, it would be much easier.
