1729 SAT: Math & Reading
Digital test prep & practice
Free · In‑App Purchases
1729 SAT is a complete prep course for the Digital SAT — both Math and Reading & Writing — built around one idea: you learn by working problems, not by watching videos.
BOTH SECTIONS, 1,959 PROBLEMS
• SAT Math: 1,110 problems across Algebra, Advanced Math, Problem-Solving & Data Analysis, and Geometry & Trigonometry
• Reading & Writing: 849 problems across Standard English Conventions, Expression of Ideas, Craft and Structure, and Information and Ideas
• 42 units in total, spanning every difficulty the SAT uses — from confidence-builders to the questions that separate top scores
PRACTICE THAT WORKS LIKE THE REAL TEST
• Interactive problems throughout: multiple choice and grid-ins with a custom keypad, fractions included
• Every problem has a hint, a scratch pad, and a full worked solution
• Reading passages and questions presented the way the digital test presents them
A PLAN BUILT AROUND YOUR TEST DATE
Pick your SAT date and each section gives you a week-by-week plan: diagnostic first, then each domain in turn, reviews, and full-length exams spaced through the run. Come back any day and continue where you left off.
KNOW WHERE YOU STAND
• A timed diagnostic in each section estimates your score on the 200–800 scale and finds your weakest domain
• Full-length adaptive practice exams that mirror the real two-module format
• Proficiency rings track every domain and skill as you practice, and always point at the skill most worth drilling next
LEARN THE TECHNIQUE FIRST
Each topic opens with a short lesson: the key definition, a worked example, and the trap the SAT actually sets. Then you practice until it sticks.
START FREE
A full domain and the diagnostic in each section are free, with no time limit and no card required: the Algebra domain in Math, and Standard English Conventions in Reading & Writing.
FULL ACCESS
One subscription unlocks both sections in full — every unit, all 1,959 problems, and all full-length practice exams:
• Monthly: $5.99/month
• Annual: $35.99/year (about $3/month)
Subscriptions are billed to your Apple ID and renew automatically until cancelled. Manage or cancel any time in Settings > Subscriptions; cancel at least 24 hours before the period ends to avoid renewal.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixes a problem where pages opened in Safari instead of in the app. The app also fits the iPhone better: controls stay clear of the status bar and camera, and problem pages give more room to the question.
