Great Program!

This program has been meticulously developed for you to train lines at any level.

However, at $40 per year, why wouldn’t you just buy a computer program, or comparable chess analysis programs, that come at $10-$25 on the higher end of the cheap spectrum. $40 per year means, if you keep the subscription for 5 years, you could buy a $200 chess program that has deeper analysis, and it allows you to store as many variations as you’d like.

This app is easily worth $5, I would struggle to pay $10, and $20 would be questionable if they developed more content pertinent to HUD associated with engine analysis.

4/5 for the product, 0/5 for the cost.

Limited without EXPENSIVE subscription

An annual subscription is $40! If you expect to still be playing Chess in a decade, and you think that you will still be using this app, that’s $400! Without the subscription you are limited to 3 files. You could do your White rep, your Black rep and 1 new line that you are experimenting with. This might work well for many people. What I want is a file for the Sicilian, a separate file for the French and so on. (Full Disclosures: I really dislike subscription software!) If not for the limitation and the cost of the subscription, the program would get 5 stars. If I could buy it for $20 or $30, I would buy it and give it 5 stars. With the price of the subscription, and the limits on the program without buying a subscription, I will keep using Splashtop and a windows based program that I have been using for years.

This app is great and would get 5 stars if it didn’t have a subscription. $40 dollar a year is an outrageous price for an app that only serves a purpose once in a while. If I build my repertoire on this app, I have to keep up my subscription. I’ll stick with ChessTrainer, one time fee. Consider making it a one time fee and I will buy plus give it 5 stars.
