And just to add on to what @bob123 said above, if you use Ledger then you are in luck. You can easily set up watch only wallets on desktop and mobile phones (using their apps).

Other options available to you together with links to guides on setting up watch only wallets (link):
- Electrum on desktop
- Samourai on Android
- bitWallet on iPhone

Also, if you are going to drop your xpub, ypub etc into a block explorer service. https://www.blockonomics.co/ (as mentioned by BitMaxz above) is good as it supports them.

Hope this helps.
