The Why tho? button: keep asking until it clicks
Why Tho? is named after its main move. Under the newest answer a small Why tho? button asks for the reason behind what was just said. Tap again and it goes deeper still, up to five levels, until the idea bottoms out.
Curiosity as the main control
Most tutors wait for you to type a better question. Why Tho? turns your "but why?" into a button. Each tap keeps the same topic and digs one layer under the last answer: from leaves turn yellow to the tree saves its nitrogen, to why nitrogen is precious.
It knows when to stop
The button counts the levels (2/5, 3/5…) and disappears when the explanation reaches its foundations, or after five levels. It also steps aside when the answer ends with a question for you, so it never answers on your behalf.
Try it
Ask a question and keep tapping Why tho? until it clicks.
