## What is ProfitReps?

THINK FASTER WITH NUMBERS

Great operators read numbers the way great readers read words — instantly, intuitively, without reaching for a calculator. ProfitReps is a daily training app that builds that skill: a few focused minutes a day of mental math, estimation, and real business judgment.

No accounts. No ads. Fully offline. Just reps.

WHY TRAIN NUMERICAL FLUENCY

Margins, growth rates, unit economics, break-evens — business runs on a small set of numbers, and the people who move fastest are the ones who read them at a glance. Like any skill, that speed comes from reps. ProfitReps gives you those reps in minutes a day, through a simple loop: CALCULATE, ESTIMATE, INTERPRET, DECIDE.

YOUR DAILY WORKOUT

Every day, ProfitReps builds you a personalized five-minute workout of 14 questions aimed at your weakest skills. The difficulty adapts question by question — answer fast and accurately and it pushes you harder, so you are always training right at the edge of your ability.

TEN SKILLS, ONE SCORE

Train ten skills across two tracks:

• Foundations — Addition, Subtraction, Multiplication, Division, Percentages, Ratios, and Estimation
• Business — Business Math (margins, markup, break-even), Number Sense (spot the reasonable answer), and Decisions (use numbers to choose well)

Your performance rolls up into your Number Score, an adaptive 0–1000 rating that blends accuracy, speed, question difficulty, and balance across all ten skills — a lopsided profile scores below a well-rounded one. Climb the ranks: Rookie, Hustler, Analyst, Operator, Founder, Executive, CFO, and finally Tycoon.

TRAINING MODES

• Daily Reps — your personalized daily workout, tuned to your weak spots
• Quick Reps — drill any of the ten skills on demand, with difficulty that adapts per skill
• Speed Reps — a 60-second sprint; chase your personal best
• Number Sense — pick the reasonable magnitude, fast
• Decision Reps — supplier deals, hires, pricing, ad spend: read the numbers and make the call
• Good Deal / Bad Deal — swipe on unit economics and sharpen your instincts
• Business Simulator — run Northside Coffee, a virtual café, through six months of decisions and watch your calls compound

FRESH QUESTIONS, EVERY TIME

Questions are generated from validated math templates with tens of thousands of variations — no recycled question banks, nothing to memorize. Every session is new, and every answer comes with the working so you learn the technique, not just the result.

BUILT TO KEEP YOU CONSISTENT

• Daily streaks that reward showing up
• Achievements to chase — from your First Rep to 1,000 Reps, Perfect Workout, Speed Demon, and the 30-Day Streak
• Progress analytics that show every skill trending over time

PRIVATE BY DESIGN

ProfitReps is 100% offline. There are no accounts, no sign-ups, no ads, no tracking, and no analytics. Your scores, streaks, and progress are stored only on your device and never leave it. Train on a plane, on the subway, anywhere.

WHO IT IS FOR

• Founders and operators who live in spreadsheets and want the numbers to feel native
• Finance, consulting, and business professionals keeping their mental math sharp
• Students preparing for case interviews, aptitude tests, or business school
