Hone Math

The Challenge

Mental arithmetic gets rusty without practice. Many drill apps are written for children or reward memorising answers without explaining a reusable method. Adults often need something calmer: learn why a shortcut works, try it, and revisit the weak spots that actually show up.

Our Approach

Hone Math is an arithmetic-method course with 71 authored skills across ten ordered units. Every skill pairs a named method with a plain-language explanation and a worked example. A three-question Prove It check can mark a method mastered; a miss restores the lesson path, and See Another Way offers a second shipped explanation when one fits. Unit Mix then combines the methods learned within one unit.

The free mental-math methods and practice guide publishes all 71 explanations and examples plus a fixed, hand-checked 24-problem web sampler. The app separately turns the curriculum into generated practice, corrective Error Repair, direct weak-spot sessions, three number puzzles, and a local progress record.

Key Features

• 71 authored skills across ten units: Foundations and times tables lead into mental addition, subtraction, multiplication, division, percentages, everyday arithmetic, test-style patterns, and number sense.
• Learn, prove, mix: Each skill teaches a named method before practice. Prove It checks mastery, See Another Way supplies another explanation when one fits, and Unit Mix combines the skills learned within one unit.
• Short Daily Workout: A focused set of 15 problems designed to take roughly three minutes.
• Practice that responds to the record: Due-skill Refresh, Smart Set, Error Repair, and direct weak-spot sessions turn prior work into a specific next action. Quick Play offers a flexible session, and Rush is a 60-second challenge.
• Three number puzzles: Make Ten, Construct, and Cross-Math; Cross-Math ranges from compact 3×3 boards to 10×10 grids.
• Recent Practice Score: A 0 to 1000 rolling practice readout based on 10 to 50 recent submitted answers, with accuracy, difficulty, and speed as factors.
• Useful progress detail: Review trends, records, strengths, weak spots, daily results, and every submitted answer.
• Local reminders: Optional daily notifications are scheduled on the device and stop when paid access ends.
• English and Spanish: The current app interface and instructional content are available in both languages.

Access and Data

After onboarding, the paywall always offers one complete shipped method lesson and the same five questions with full feedback, without a purchase. The sample can be repeated and changes no score, adaptive level, streak, history, mastery, or Error Repair queue. The full course and fresh adaptive practice require an active monthly or annual subscription; there is no permanent free tier for those features. Eligible new subscribers may receive a 3-day trial. StoreKit displays the current local billed amount, eligibility, renewal period, and terms before purchase. A retired lifetime product is not sold, but verified earlier owners retain full access through Restore Purchase.

The data door never depends on a subscription. From the hard paywall or the You tab, inspect the complete local record, export lossless JSON plus a readable plain-text summary, or delete it. Deleting the record does not cancel an Apple subscription.

There is no Studio AM account, advertising, analytics, tracking, cloud sync, or Studio AM data server. Practice works offline and progress stays locally on the device. StoreKit needs a connection to Apple for plans, purchase, restore, and entitlement verification; a user-requested export leaves only through the system share sheet.

Results

Hone Math gives adults a structured way to learn practical arithmetic methods, prove or revisit each one, repair their own mistakes, and act directly on weak spots without ads or a child-focused reward system.

What does Hone Math teach?

The curriculum contains 71 authored skills across ten units: foundations, times tables, mental addition, mental subtraction, multiplication, division, percentages, everyday math, test-style problems, and number sense. Every skill includes a named method, a plain-language explanation, and a worked example.

How does practice work?

Learn opens as an ordered course. Each method has a worked example, a three-question Prove It check, and another explanation when a second shipped method fits. Unit Mix combines methods from one unit. Daily Workout gives a short adaptive set, while due-skill Refresh, Smart Set, Error Repair, and direct weak-spot practice respond to your record. Quick Play, Rush, Make Ten, Cross-Math, and Construct offer other practice shapes.

What is the Recent Practice Score?

It is a rolling practice readout from 0 to 1000. It appears after 10 answers and uses between 10 and 50 of your most recent submitted answers, with accuracy, difficulty, and speed as factors. It reflects recent practice rather than a lifetime exam score.

Can an earlier lifetime owner restore access?

Yes. The old lifetime product is no longer sold, but verified earlier purchasers retain full access. Use Restore Purchase on the paywall with the same Apple Account that made the purchase.

Is Hone Math private and does it work offline?

There is no Studio AM account, advertising, analytics, or tracking. Practice and progress work offline and the record stays locally on the device. An internet connection is needed for Apple to load plans, purchase, restore, and verify subscription access. User-requested exports leave only through the system share sheet.
