If you are someone who is starting and just want to see that it works, you can use wallet of satoshi or getalby. But you have to know they will probably also force you to kyc one day and you don't have the keys.

Then you can try something like Phoenix or Breez which are nodes on your phone without all the complications of managing channels.

For small amounts I wouldn't be bothered to create a separate profile or new device. Android should do a good job isolating the apps. IOS too I guess but I have no idea about apple products
