KittyKitty Add Subtract is a math game for teaching preschoolers and kindergartners the basic concept of addition and subtraction. Older kids may also benefit from practicing simple addition and subtraction and collect rewards. Prerequisites: - ability to count up to 20 - ability to read numbers, "+" and "-" signs * Knowledge of addition and subtraction is NOT required * Let the kid work out the answer! Unlike most of the early math educational games on the market, we not only just provide questions and answers. We also provide a working area for kids to work out the answers on their own... with wiggly KittyKitties! Guidance may be required for the first few questions, but you will be amazed by how fast your kid can understand the basic concept by adding and subtracting kitties. Progress tracking and difficulty adjustment The game saves the progress of each child and adjust the difficulty of the questions as the child progress. After the child completed a certain number of questions, he/she will get a certificate to acknowledge his/her achievement. Collect rewards and practice more! Practice makes perfect. A reward system to collect KittyKitty's outfits is in place to encourage kids to do more questions. Free to play and only one ad per game session We understand how annoying it is to have ads popping up while your child is playing games. So we limited the ads to only show once at the beginning of the game. Or you can remove ads with a cost.

Undumb is a short daily workout backed by a Harvard-educated forensic psychiatrist to keep your brain sharp when using AI regularly. Workouts help with creativity, critical thinking, and focus. We built Undumb because hard thinking is a skill worth practicing. In the modern workplace, AI tools can make work faster and are often becoming required by employers. We still want to read carefully, notice weak evidence, make our own calls, and explain what we think but the modern pace of work with AI doesn't always allow for that. Undumb offers short daily questions that help anyone deliberately train the parts of their brain that over-using AI impacts. Think of these puzzles as a workout or gym routine for your brain. Each puzzle is hand crafted with intention to help people experiencing AI-brain-drain. Your first seven workouts are free. Complete Workout 7 to unlock your Cognitive Profile, with starting scores for Creativity, Critical thinking, and Focus. As you progress further, you can see how your scores are trending over time.
