I love this app! It's very versatile as it has both standard and scientific calculator. A currency converter is planned to be added soon too making it a one-stop shop for many types of calculations and conversions. Tha AI math solver that scans equations right from the notebook is a huge time-saver, though it's only available with a premium subscription. Overall, it's a great app and I highly recommend it!

Hello! We use ads to keep the app free and support its further development. We are aware that ads are always a compromise, but we never want ads to prevent from using the app. Are there any features or pages that are particularly affected by ads? Best regards, Nadia
