The Karnaugh map is a method to simplify Boolean algebra expressions. In a Karnaugh map the boolean variables are transferred (generally from a truth table) and ordered according to the principles of Gray code in which only one variable changes in between adjacent squares. Once the table is generated and the output possibilities are transcribed, the data is arranged into the largest possible groups containing 2n cells (n=0,1,2,3...) and the minterm is generated through the axiom laws of boolean algebra. We have designed this application primarily to support students studying electronic engineering, although it is useful in other disciplines including computer science and mathematics. Features: - Minimize logic function entered as text, Karnaugh map or truth table - Up to 8 variables - Contains History option - Supports the Don't care condition - Shows representation of each minimized component in the Karnaugh Map

VoiceMaxxing turns a short speaking sample into an explainable training plan. Record your natural voice, review five practical speaking metrics, complete focused daily exercises, and compare your progress with consistent weekly recordings. MEASURE WHAT YOU CAN TRAIN • Clarity • Pace • Presence • Tonal variety • Fluency A quality gate checks duration, speech activity, recording level, clipping, and background noise before producing a result. Voice Score is an educational within-person comparison—not a judgment of attractiveness, masculinity, personality, or health. PERSONALIZED DAILY PRACTICE Your goals and latest measurement shape a focused 5–8 minute plan. Each exercise clearly shows: • The exact sentence or speaking prompt • Duration and repetition target • Microphone activity and completion rule • A practical coaching cue • Safety guidance BUILD PROGRESS THAT CONTINUES The first 30 days establish the foundation; the program does not stop there. Weekly re-measurements update your focus, continued levels unlock, and free practice lets you revisit clarity, rhythm, expression, voice, or saved favorites whenever you want. HEAR THE DIFFERENCE Compare your baseline and later recordings under similar conditions. Track Voice Score and every component metric over time instead of relying on a single number. PRIVACY AND SAFETY Core analysis can run on device. Speech insights and cloud analysis require separate consent. VoiceMaxxing is an educational self-training tool, not medical diagnosis or voice therapy. Stop if you experience pain, burning, breathing difficulty, dizziness, or persistent hoarseness and seek qualified care. VoiceMaxxing Pro is available as weekly and annual auto-renewing subscriptions. Payment is charged to your Apple Account. Subscriptions renew unless canceled at least 24 hours before the end of the current period and can be managed in Apple Account settings.
