iOS. Coding interview prep.
You can solve it.
Can you explain it?
Interviews grade the part you never practice: saying it. Speak your reasoning, watch each idea land as a card, and talk your way from brute force to optimal.

Why it works
The interview tests the talking, not the typing.
No time
Prep in the time you already waste
Nobody grinds three hours a night around a full-time job. Do one rep between meetings, on the commute, in the queue for coffee. No laptop, no desk.
The freeze
Solved at home. Blank in the room.
You had it ten minutes ago. Then someone watched, asked you to talk through it, and the words went. This is where you rehearse the talking.
Burnout
Stop memorizing. Start reasoning.
You forget the pattern by Friday because you never said it out loud. Talk a brute-force idea into the optimal one and you keep the why.
The mechanic
Speak it. See it. Sharpen it.
Say the naive version
Start where a real interview starts. Two loops, O(n²), out loud. It lands as a card.
Read back what you said
The card carries working code, so you can see whether you described what you meant.
Talk it to optimal
Say the improvement. A second card branches off the first, and the flow is your reasoning.
Pricing
One plan. No weekly trap.
about $10 / month
