Other than tracking things on a piece of paper or in Excel (or similar), do you use or know of an ANDROID app that will keep track of borrowed or lent things?

It would have to keep info in the cloud so that if I reset my phone, upgrade it, etc. the info isn't lost.
It would be nice if the app had cross platform capability so I can open it on my office PC, but that's not critical.

I found few apps so far.
"I lend you", "I.O.U.", "Where is my stuff", and few others, but wanted to hear your opinions.

Background info:
I spent hours looking for my framing nail gun yesterday.
Over 2 hours of actual search, + rest of the day distracted, thinking about possible people I could have lent the tool too. I texted and called several friends and family members.
Frustrated and embarrassed, I posted on Facebook about it.
Friend remembered borrowing it and I got my item back :-)
