Yes for sure! You can use Otsimo apps on up to 3 devices but you should definitely sign in with the same method, for example if on one device you signed in with your Apple ID then you have to sign in with your Apple ID on the other device to access your account. The type (phones/tablets) or operating system(iOS/Android) of your device does not matter . If there is another problem you’re facing make sure to contact us at support@otsimo.com
