About

Vigilance

Read full description

Vigilance-Test gives you a simple way to check your current reaction readiness. With clear procedures, a clean design and precise measurements, the app shows you how quickly you react to visual signals – ideal for getting a sense of your current attention and daily form. Test procedure: A timer appears randomly after a short waiting period. As soon as it becomes visible, you tap or press as quickly as possible. The app records your reaction time, detects false reactions and shows you a clear summary with charts at the end. Choose between 1, 5 or 10 minutes – the longer the test, the more meaningful the result. Long-term statistics: Over time, a personal picture of your vigilance emerges. Interactive charts show you reaction time trends, false reactions, time-of-day patterns and consistency – all at a glance, freely arrangeable and filterable by test duration. Long-term statistics must be unlocked via an in-app purchase. Tags: Mark each test with a tag – such as "Caffeine", "Tired" or "Exercise" – and directly compare how different states affect your reaction time. The app is suitable for, among other things: * Self-observation of your own vigilance throughout the day * Training or work breaks to assess your sense of concentration * Curiosity about how fatigue, focus or different times of day have an effect Privacy: Vigilance-Test does not process any personal data other than the data necessary for the app's functionality. This data remains locally on your device or – if enabled – in your iCloud account. Vigilance-Test requires no login, uses no trackers and is completely free of advertising. Vigilance-Test is a straightforward tool that helps you better assess your own state of alertness – without any diagnostic claim.
