Lifter is a balance method trainer focussing on linear equations. Practice your skills of solving linear equations in four difficulty levels. The app randomly generates questions, but you can also enter in a custom equations from something like your maths textbook.

Unlike other trainers, Lifter uses movable cranes with boxes on top instead of a scale/balance to show the current value. We did this for the following logical reasons:
- When the value gets higher, the crane goes higher. With a scale it would have to go lower.
- Boxes have no weight, the crane height just represents the values. A box of a negative number would make no sense on a scale.
