Warning - Do NOT Buy This!


Unfortunately, I'm not allowed to rate less than 1 star.

The description states that you can set up alerts to be sent via email or SMS. It doesn't state that for the$4.99 purchase price, you'll only be allowed 5 SMS alerts. SMS alerts are an additional purchase. That is NOT mentioned in the description. The usual "in app purchase" line near the bottom is left off of the description page, where a reputable app would state purchase prices (ex: 50 SMS for x amount of dollars).

5 SMS alerts are not worth a purchase price of $4.99 with undisclosed additional purchases. DO NOT BUY!

Can I get a refund?


App is not useful for me because you only get 5 SMS after paying for the app and I had to pay 4.99 for 50 more. This was not mentioned before you buy it.. very disappointed. Don't wast your money. I'd like a refund but probably won't get one. Buyer beware

Wie praktisch!
