User reviews

Great App but for one thing…..

The Month/Day/Year format really screws things up for users not in the USA. An option to change it to a Day/Month/Year would be appreciated, or replace the numerical month with letters to avoid confusion.

Scam?

I have been charged twice for this app within a couple of days of each other

Not bad

Nice simple app. It would be better if you could have them colour coded say red/green or tagged for who you owe / who owes you. Also if you could do +/- to put in payments vs when you’re leant or borrowed more money from the same person, rather than starting a whole new transaction.

But overall not bad for tracking stuff compared to another I tried

Would be great if it works

After entering a few transactions. It shuts down. The y can’t open any info back up. Paid the fee , Contacted developer. Said would look into it. As of yet. Nothing ……..

Easy and good!

This App, is very easy to use and it keeps really good records of payments and then you can send or even screenshot the history and amount due to the borrower or loaner.
It does all I need.
