What this app is. What it isn’t. What you could build.

One-liner

A simple Rubik's Cube solver and timer app that helps users solve cubes step-by-step and track their solving times.

Strengths

Provides clear, step-by-step solution guides for beginners (review: 'The tutorial helped me solve my cube for the first time!')
Includes a functional timer with lap and session tracking (review: 'Great for practicing speedcubing')
Lightweight and fast with minimal ads (review: 'No lag, just works')
Supports multiple cube sizes (2x2 to 5x5) in solver mode
Clean UI with intuitive navigation

Weaknesses

Solver lacks advanced algorithms (review: 'Only basic layer-by-layer, not CFOP')
Timer lacks split timing or heat map analytics (review: 'Missing stats I need for improvement')
Ads interrupt solver steps (review: 'Pop-up after every step is annoying')
No offline mode for solver (review: 'Can’t use it on plane without internet')
No community or sharing features (review: 'Would love to compare times with others')

Opportunities

Build a pro-tier solver with CFOP/ Roux/ ZZ method support and video walkthroughs
Add offline solver and advanced timer stats (e.g., best/average of 5, move count)
Integrate a lightweight community feed for sharing solves and PBs
Offer a premium tier with ad-free experience and exportable solve logs
Target non-Japanese users by adding English-only interface and tutorials
