Takes a little bit if time to get used to, but so does most budget software. I will say for me the App works the best on the iPad and my computer.
Once you get the hang of it works great as a budget tool. Ive been using it for the past three years. I have it on my iPhone, iPad and Mac laptop. Syncs to all three devices. It has really helped us get control of our finances.
Having to pay for add ons is a bit if a bummer, but the add ons are cheap, so its not that big if a deal. I wouldnt recommend using budget touch on your iPhone as the primary tool, but it works great in conjunction with budget on the computer. Would work fine as a primary tool on the iPad.
