Ratings and reviews

UPDATE: they make you pay to access anything after 1 week! NO free part at all, lost all data too, don't try this! Greedy AF! Shame. At least have a free/ad side. Old review: Simple, straightforward, easy to use. Most importantly, visually great, I can see my progress clearly. Wish more apps were like this, just simple straightforward without unnecessary clutter.

No longer free. Was never warned that it was a trial for only a week. I've been using it for months. It also has ads. Pay 5 bucks once to check things off and get back ups. Given the lack of communication in changes, just find a free app that does the same unless you really like this one. General PSA: Don't click ads on any app, many contain viruses/malware for phones and companies don't vet there sponsors ever.

Great Accomplishment and Affordable. The matrix is very smartly configured and easy to arrange to suit my personal needs. Really, finding an app of this quality for a one-time full purchase is rare. Most of the others I considered were expensive subscriptions. Those wanting to get this for free are admitting that they like it the best. If you can afford a phone, you can easily make a single payment for this. WISHLIST: encryption, more data graph options (like candle stick), backup choices.
