Have you ever experienced not understanding how to solve a problem, even after seeing the answer? With this app, you just take a photo of the problem you don’t understand and send it – AI will explain the solution to the physics problem in detail. * Depending on the problem, the answer may be incorrect. Please understand. This service uses AI, and since providing it for free is difficult, you can try it for free up to 2 times if you send only an image or only text, or 1 time if you send both image and text. After that, you will be guided to the Premium plan. AI Physics Questions Monthly Subscription $5.99 per month This is an auto-renewing subscription that allows you to use the explanation feature within the app unlimited times.
