DeTeXt vs FireAPT

Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the commands and packages for every symbol. DeTeXt tries to solve this problem by giving you two ways to find the command you want: - Draw the symbol you want and DeTeXt's neural image classification engine will identify what it thinks are the 20 most likely LaTeX commands that will generate a symbol closest to the one you drew. DeTeXt supports Apple Pencil drawings on the iPad. - Search the entire symbol set of 1098 symbols from packages like tipa, amsmath, amssymb, textcomp and more, in addition to the default mathematical symbols. - Copy the symbol, or the character itself, or its Unicode codepoint to the system clipboard, to paste anywhere else. DeTeXt's neural engine processes your drawn symbol and finds the best matches in its symbol database, all on your device without requiring you to be online. All the symbols are stored within the app as well.

FireApt is a focused practice app for anyone preparing for a firefighter aptitude assessments. 1,360 original questions across the four skill areas (Numeracy, Literacy, Abstract & Mechanical), every one with a worked explanation — because knowing you got it wrong teaches you nothing on its own. WHAT'S INSIDE • 1,360 original questions — 340 each in Mechanical Reasoning, Numeracy, Literacy and Abstract Reasoning • A worked explanation for every single question, not just an answer key • Over 1,800 purpose-drawn diagrams: pulleys, gears, levers, circuits, pattern grids • Timed practice exams — 40 questions across all four areas against a 30-minute clock, drawn fresh every time (now customisable) • Reading comprehension built on realistic documents: standard operating procedures, incident reports, safety bulletins, station notices THE FOUR AREAS Mechanical Reasoning — gears, levers, pulleys, hydraulics, forces and how things move. Numeracy — ratios, rates, percentages, unit conversion and the practical calculations the job actually asks for. Literacy — comprehension, inference and clear written communication, including passage sets drawn from the kinds of documents you would read on station. Abstract Reasoning — pattern sequences, matrices and odd-one-out problems that test reasoning independently of prior knowledge. TRACK WHERE YOU STAND Your results are broken down by skill area, with your average, your best and your latest score for each, plus a trend line across every session you have completed. The point is not the score — it is knowing which area to spend your next hour on. BUILT TO STAY OUT OF YOUR WAY • Works completely offline. Every question and diagram ships with the app, so it runs on a train, in a basement, or anywhere with no signal. • No account, no sign-up, no email address. • No ads. No subscriptions. No in-app purchases. You buy the app once and you have all of it. • Nothing is collected about you. Your practice history is saved on your device and never leaves it. WHY IT COSTS WHAT IT COSTS Every question, explanation and diagram here was written and drawn from scratch. There is no recycled question bank behind it, no advertising, and nothing to upsell you once you are inside. One price, everything included, forever. A NOTE ON PREPARATION No practice app can tell you what will be on your assessment. What it can do is make the formats familiar, so that on the day your attention goes on the problem rather than on working out what is being asked. That is what this is for.
