An SAT prep app gives you digital SAT practice questions, explanations and mock tests on your phone, so you can practise a little every day. Some build a plan from a target score, some give a short free set each day and some add an AI tutor. Ten apps follow, in no particular order.
The digital SAT rewards steady practice more than last-minute cramming, and a phone is the one study tool most students carry everywhere. Ten questions before school or on the bus can do more than a three-hour session you keep putting off.
The ten apps below are listed alphabetically and in no particular order, and every description comes from the app's own App Store listing, read this week. If the essays for your college applications are next, my guide to ChatGPT prompts for essay planning helps you plan without losing your own voice.
SAT prep apps compared
I checked the free plan column on each app's own App Store listing, as of Oct 2026. Yes means the listing names a free app, a free version, a free tier or free content. Trial only means a time-limited trial. Not stated means the listing I read named neither, even where there's a download button, so check the app's own page before you subscribe.

How the digital SAT adapts to you
College Board says the SAT has two sections, Reading and Writing, which takes 64 minutes, and Math, which takes 70 minutes, for a total of 2 hours and 14 minutes. Each section is split into two equal modules, with a 10-minute break between the sections.
The part that matters for practice is this: the second module of each section gets harder or easier depending on how you did in the first. That means a strong first module opens the door to the higher scores, so accuracy early on counts for a lot.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
For the UK equivalent at school age, try GCSE revision apps.
Untimed questions versus timed modules
Most apps let you answer questions one at a time with no clock, which is great for learning. But the real test is timed module by module, so at some point you need to switch to timed sets.
A good rhythm is untimed practice while you're learning a topic, then timed modules once you're getting most questions right. That way you build both understanding and pace.

A six-week SAT routine
- Take one full practice test to find your starting point.
- Spend two weeks on your two weakest skills with short daily sets.
- Add timed modules in weeks three and four.
- Take a second full practice test in week five and compare.
- Use the last week for light review and the official practice app your school uses.
Do you make SAT, ACT or college admissions prep apps? Tool makers can ask to be considered for a featured place on this list.
My plain advice on SAT prep apps
Choose one app and use it daily, even if it's only ten questions. Students who practise a little every day usually do better than those who binge, and it's far easier to keep going.
Before test day, make sure you've practised in the official testing app your school or test centre uses, so nothing about the screen surprises you. For the rest of your study life, my guide to productivity tools for students can help you stay organised.
