Good for one-off check
App is bulky with lots of features already in iCloud. If just checking your phone once, its safe to decline the location, notification and contacts permissions. Also requires an account to be created, but it seems you can use the app even with an invalid email address and random password.
Installed to check Pegasus status and then uninstalled. Would have been better to have a dedicated Lookout Pegasus-Check edition that just does that :)
