Hydra Psychology Trainer – targeted training for demanding selection processes Hydra Trainer is your training environment for cognitive performance – ideal for preparing for psychological aptitude tests in selection processes, e.g. for the police, special forces, leadership courses or other security-related professions. The app bundles typical test formats in a clear, iOS-inspired interface so you can practise in a structured way and track your progress. What to expect • Number sequences & equations Practise logical and mathematical thinking with number sequences and incomplete equations. The tasks become progressively more difficult and challenge your pattern recognition skills. • Matrix & pattern recognition Train your figurative-logical thinking with matrix tasks, as found in classic intelligence and aptitude tests. Perfect for grasping regularities and structures more quickly. • Anagrams & word finding Solve anagrams with a focus on nouns and infinitive verbs. This trains your word finding, concentration and spelling under time pressure. • Pauli-style arithmetic tests Continuous arithmetic under pressure: task formats based on the Pauli test help you to increase your speed and accuracy in mental arithmetic. • Folding Template Test Train your spatial awareness and mental rotation by identifying the correct folded shapes from folding templates. • Occluded Motion Test Train your ability to predict movements by determining the positions of objects that continue to move behind a screen. • Memory test Strengthen your working and short-term memory with tasks that require you to keep changing information in mind over several steps. • Stroop, d-Test & Form Focus Test Train selective attention and concentration: the Stroop test challenges interference control, the d-Test targets selective attention, and the adaptive Form Focus Test is inspired by the FAKT II. • Leaderboard & account Compete with others: sign in with Apple or Google and submit your test results to the leaderboard. You can delete your account and all submitted results directly in the app at any time. • Adaptive difficulty & evaluation Hydra Trainer adapts tasks and difficulty levels to your performance level. After each test, you receive feedback on errors and processing time so that you can work specifically on your weaknesses. • Concentration without distraction Sleek, system-oriented design in iOS style: clear typography, calm colours, no unnecessary ‘gamification’ ballast. You concentrate on the essentials – the task. Who is Hydra Trainer intended for? • Applicants for police, special forces, pilots, air traffic controllers, studies (especially medicine, psychology, pharmacy, etc.) • Participants in selection and leadership courses • Anyone who wants to train their cognitive performance in a structured way Note / Disclaimer Hydra Trainer is a training and exercise tool for preparing for performance and aptitude tests. The app is not a medical or psychological diagnostic or therapeutic tool and does not replace professional diagnosis.

Nun geh ich auf die App und man kann jedes Modul und jeden Test nur noch mit einem Pro Abo benutzen.

Your Pro access is available wherever you are signed in, including purchases made in earlier versions. ### 3.1.1 — 2026-08-30 Version 3.1.1: • New module Cube Folding: fold cube nets in your head and pick the matching view. 20 tasks across five difficulty tiers, with training mode, error review and leaderboard. • New: community forum. Ask questions, report bugs and talk to other users right in the app (for signed-in users). • Folding templates test: fixed 11 tasks with faulty solutions or answer options. Thanks to everyone who reported them! • Test start screens no longer get clipped at large text sizes. ### 3.1 — 2026-08-26 Version 3.1: • Hydra now runs in the browser as well: keep training at app.hydrapt.com on a laptop or tablet, with the same account, the same progress and the same leaderboard. The app shows this note once after the update. • Equation test: on ambiguous items a mathematically correct answer could be marked wrong. Any filling that makes the equation true now counts. • Anagram test: fixed faults in the German word list. Words no longer appear with trailing digits, ss is only used where ß does not belong, and the ß tile shows one character instead of SS. A few questionable dictionary entries were removed as well. ### 3.0.4 — 2026-08-13 Version 3.0.4: • Form Focus: the leaderboard now scores every submission on the fair, guessing-corrected scale, including those from older app versions. Inflated results can no longer distort the rankings. ### 3.0.3 — 2026-08-11 Version 3.0.3: • New point-based scoring for the Matrix and Paper Folding tests: instead of a percentage, your score is now difficulty-weighted with a speed bonus. Harder tasks earn more points, and even flawless runs can be told apart. • Matrix test: item selection now reliably serves the hardest tasks to very strong runs. • Form Focus: fairer scoring with guessing correction and finer difficulty adaptation. Older results of this module are removed once, as they are not comparable with the new scale. ## More apps by Midnite Compile GmbH - [SetGo Timer](https://appshunter.io/ios/app/setgo-timer/id6761116608) - [Birth Timer](https://appshunter.io/ios/app/birth-timer/id6772555600) - [Riff Capture](https://appshunter.io/ios/app/riff-capture/id6779860797) All apps by Midnite Compile GmbH: https://appshunter.io/developer/1850145762 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
