FE4RACCOONS

The phone app

FE for Raccoons, now on your phone

Short rounds built on the same drawings you study on the website. Read a figure, make the call, and see why, in the few minutes you have between classes. Completely free.

Days studied: 27 days since August 3, with a calendar of the days you studied.
A round on a flow net under a sheet pile wall, asking which way round the flow channels and head drops go in the seepage formula.

How a round works

  1. The app's Study tab, showing the Mathematics chapter with the next lesson and a Continue button.
    1

    Pick up a lesson

    The app follows the same 15 chapters and lessons as the website. Open the chapter you are studying and keep going from where you left off.

  2. A round asking which point on a Mohr's circle is the largest stress pulling a point apart.

    Read the drawing, make the call

    Each round puts a real engineering figure in front of you: a flow net, a Mohr's circle, a truss. You answer on the drawing itself, the way you read figures on the exam.

  3. A concept sheet on deep foundations: a footing on soft clay, then piles carrying the load past it.

    See why it works

    Every concept starts with a picture and a few short steps, so the next round makes sense before you play it, and points you to the handbook section it comes from.

Why it keeps you coming back

Two ideas borrowed from apps people already open every day, put to work on the FE.

Chapter 1 as a path of lessons: Straight Lines, Logarithms and Right Triangle Trigonometry cleared, one after another.

The chapter path

A path through every chapter, inspired by Duolingo

Each chapter is a road of lessons you clear one at a time, the same idea that keeps millions of people learning a language a few minutes a day. You always know where you are and what comes next, and short steps make it easy to come back tomorrow.

Today's Daily before you play: three concepts from three chapters and a Play button.
The Daily results screen with a chart of how many players got each score and a list of the fastest players, shown with sample players.

The Daily

One challenge a day, inspired by Wordle

Three games from three chapters, the same for every student, played once a day. When you finish, you see how everyone did and where you landed. Once enough students from your school play, your school gets its own board.

Sharing your result shows your score and time without giving away a single answer, so a friend can still play it fresh.

The results screen above is shown with sample players.

Made to work with the website, not replace it

The phone is for the minutes in between. Full problems and your mastery score live at the desk, where you have paper and the handbook open.

On your phone

  • Short concept rounds on real drawings, one idea at a time.
  • The Daily, the same three games for every student.
  • A warm-up that keeps the ideas fresh between study sessions.

At your desk, on the website

  • Full FE-style problems with step-by-step solutions.
  • The diagnostic that builds your study plan.
  • Mastery, earned only on full problems. Rounds on the phone never inflate it.
The app's mastery screen: 21 percent, earned at the desk on the website, with a chart of which chapters to work on first.

One account for both. The days you study count across the app and the website, and the practice you do in the app shows under each chapter on your dashboard.
