Tracker a massive disappointment

Extremely Challenging: Mainly 2 challenges. 1) The Tracker application does not work on my wife's mobile phone. I requested Tracker on several instances for assistance and had none. 2) When capturing fuel expenses on the Tracker mobile app, quantities can only be rounded to 1 decimal, but fuel prices cannot be rounded at all, resulting in incorrect total amounts captured. This then has to be edited afterwards on the Tracker internet webpage, which is an unnecessary inconvenience. Tracker's response is that they never advertised nor promised that this feature should work on the mobile application. Imagine this push back as a technicality. I followed-up on several occasions. Logged these problems with them on several occasions without any successful follow-up or outcome. Challenges continues. Tracker is a huge disappointment.
