Hone Math
Mental math drills for adults
A few focused minutes of mental math a day, built for adults. Track your Mental Math Index over time with a clean, editorial design — no ads, no subscription.
The Challenge
Mental arithmetic is a skill most adults quietly lose. Brain-training apps exist, but they tend to be gamified for kids, locked behind subscriptions, or padded with ads and guilt-driven streak mechanics that punish you for taking a day off.
Our Approach
Hone Math is a daily workout designed for adults: three focused minutes, a single score that tracks real progress, and a calm, editorial interface. The free version has no ads and no subscription — Pro is a one-time unlock.
Key Features
- Three-Minute Workouts — A short daily session that fits between meetings, not another open-ended time sink
- Mental Math Index — A 0–1000 score that tracks your sharpness over time
- Earn-Back Streaks — Miss a day and earn it back; consistency without guilt loops
- Editorial Design — Clean typography, light and dark themes, no cartoon mascots

- Honest Pricing — Free to use daily; one-time $4.99 unlock for lifetime Pro access
Results
Hone Math makes a daily habit out of staying numerically sharp — a few minutes a day, measured by a single number you can watch improve.
