Trail Buddy
The Trail Making Test app for measuring visual attention, processing speed, and task switching in a simple, controlled way.
Available on iOS and Android.
Based on the classic Trail Making Test
Trail Buddy implements the classic Trail Making Test (TMT), where participants connect numbered circles in sequence (Part A) or alternate between numbers and letters (Part B). This well-established neuropsychological test reveals visual attention, processing speed, and task-switching ability.
TMT Parts A & B
Run both Trail Making Test Part A (number sequencing) and Part B (number-letter alternation) to measure processing speed and cognitive flexibility.
Structured data
Collect completion times and error counts per session, so you can track performance changes over time and compare across participants.
Fits the Research Buddies toolkit
Combine Trail Buddy with Stroop Buddy, Vigilance Buddy, and NBack Buddy to cover multiple aspects of cognitive performance in your study.
For theses, research projects, and clinical assessments
Use Trail Buddy for thesis projects, research pilots, or cognitive screening. Because sessions follow the standardised TMT protocol, results fit naturally alongside data from Stroop Buddy, Vigilance Buddy, and NBack Buddy in your study.
Trail Buddy FAQ
Can I use this app for my bachelor or master thesis?
Yes. Trail Buddy is designed to make it easy to run Trail Making Test sessions that you can compare over time and relate to other cognitive measures in your study.
What is the difference between Part A and Part B?
Part A asks participants to connect numbered circles in order (1-2-3…), measuring basic processing speed. Part B requires alternating between numbers and letters (1-A-2-B…), adding a task-switching component that tests cognitive flexibility.
Does the app record errors as well as completion time?
Yes. Trail Buddy logs both completion time and errors, giving you a fuller picture of each participant's performance on the Trail Making Test.
Use Trail Buddy with other Research Buddies apps
Combine Trail Buddy with Stroop Buddy for Stroop Tests, Vigilance Buddy for Psychomotor Vigilance Task (PVT) tests, and NBack Buddy for N-back working memory training, or visit the Research Buddies home page to discover all apps.
