Yes, in the application there is an advertizing from operator Leadbolt (Mobile Advertising | Leading Mobile Ad Network | LeadBolt). One is called by the button the TOP APPS, another will appear in the notification panel each four days if you won't interest advertized simply clear the panel of notices. It seemed to me that it is better, than constantly hanging banner on the game screen.
Well if You have this problem, try to use the program every day. I have one comment from a person my program really helps to cope with the real disease. "Advantageous. I have a braindamage and therefore some problems with short memory seeing the bigger perspective. This app may help improve, not it all, but some of the lost sides after my illness. Training, training, training!!!"
Yes you are right, here as in all important regular exercise, 15 minutes a day and after some time, you will be able to feel the difference. This technique was used for training of concentration and switching attention from the Soviet pilots.
Nice app! I like the focus on brain concentration. Seems like health and wellness apps focus so much on dieting and exercise for the body that we forgot the brain!! Anyway, I'd encourage to remove the ads for now to grow user base - much easier to get installs, better user ratings and experience! Once you achieve critical pass, you can slowly implement ads to monetize the app.
I'm glad You enjoyed my app. Thanks for the advice, but I don't think the reason in the presence of in-app advertising, in my application, weight Control or TABATA timer, too, is advertising, however, the number of downloads is higher than Concentration, as you correctly noticed, people tend to train the body, forgetting about the brain.
Cool game app and challenging! Did you ever consider having a headset to actually measure brain activity while playing this app? This is actually a brainwave headset made for that and it's launching in Indiegogo soon.
