I am traveling to Tokyo, solo, next week for the first time. Staying at the Hilton Tokyo in Shinjuku

I do not speak nor read Japanese, but have done my homework on things to do and see, along with time to just wander.

I am wondering if any other Tokyo residents/visitors have any apps they would recommend that would potentially make this a better/easier/funner trip, other than translation apps.

Thanks in advaance!
