Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- After you finish all 100 problems, a full-screen ad now appears on the way to the result screen. It never interrupts you while you are calculating.
- If you buy "Remove Ads (one-time purchase)", neither the full-screen ad nor the banner is shown. If you have already bought it, nothing changes for you.
