In this test training, you will encounter colored triangles in different directions and must react quickly and accurately according to clear rules. The principle is simple but challenging: it trains precisely those skills that are also required in cognitive performance and pilot tests—attention, rule application, reaction speed, and perseverance.

The Triangle Test turns your iPhone or iPad into an effective training tool for your mind. Features • Targeted training for focus, perception, and reaction speed • Ideal for preparing for parts of the pilot test or similar aptitude tests • Simple but scientifically inspired test principle • Clear, intuitive user interface • Local storage and evaluation of your progress • Perfect practice without delays thanks to optimization for iPhone and iPad Whether as a short daily workout or targeted preparation for demanding test procedures, Triangle Test strengthens the mental abilities that really matter.

The day that decides your dream of the cockpit is getting closer. With DLR Test Trainer you walk in prepared, not nervous. The app trains all ten computer-based test types of the DLR pilot aptitude test (Stage 1), used by SWISS and the Lufthansa Group with the European Flight Academy, among others. Every task is freshly generated, so you train the skill, not the answers. The 10 test types • SKT Triangle test: rules under time pressure • VMC Visual memory: n-back with shapes and colors • RMS Running memory: enter heard digits backwards • KRN Mental arithmetic: tasks you only hear, never see • OWT Instrument reading: nine gauges in a few seconds • PPT Cube folding: which cube matches the net? • WFG Path figures: count the turns, crossings included • TVT Technical comprehension • PHY Physics • ENS English Know where you stand • Placement test: five short exercises in about 5 minutes show your strengths, your focus modules and a recommended starting level. • Compare yourself: see how your first placement test stacks up against other applicants, anonymous and only if you want. • Test readiness from 0 to 100: one number for your level, with the change since last week and your biggest lever. • Target traffic lights per module: green, amber or red against benchmarks from candidate reports. • Error analysis after every session: concrete hints on where you lose points. • Adaptive levels: three greens in a row and the app suggests the next level. Stay on track • Countdown to your test date, daily goal and streak with streak freeze • XP, ranks and 23 achievements • Reminders that fit your day Pro • All 10 modules without limits • Exam simulation: all modules back to back in the order of the test day, full (about 60 minutes) or compact (about 30 minutes), with a report • Training plan up to your test date and history charts Pro is available as a monthly subscription (cancel any time) or a one-time lifetime purchase. Free • Cube folding, path figures, technical comprehension and English free forever • Try each of the other six modules three times for free • Placement test, test readiness, error analysis and level suggestions included For other pilot aptitude tests too Mental arithmetic, spatial reasoning, memory, concentration, technical knowledge, physics and English are part of almost every pilot aptitude test, such as SPHAIR, COMPASS or military pilot selection. Private and offline No account, no ads. Your training data stays on your device, with export and import for a new device. Only if you choose to compare yourself with others is the result of your first placement test sent anonymously. In 10 languages, on phone and tablet. Note DLR Test Trainer is an independent app and is not affiliated with the German Aerospace Center (DLR). It contains no original test items, only its own recreations of the test formats.
