What's New in BASLN
2.0.0
May 18, 2026
This update fixes a bug from an earlier version that may have caused sample test data to appear in your history, including an inflated streak counter. If you were affected, BASLN will automatically clean up the unwanted data and rebuild your streak and baselines from your real sessions within a few seconds of opening the app. If anything still looks off after updating, go to Settings → Data Recovery → "Rescan for sample data" to flush any records that may have arrived later via iCloud sync. Your real test results are preserved. Thank you for your patience.

FAQ
What is BASLN?
BASLN is a health and fitness app designed to measure your actual cognitive performance through a series of research-validated tests. It focuses on metrics like reaction time and cognitive function, rather than just heart rate or sleep stages.
How does BASLN establish a personal baseline?
Your first five sessions with BASLN are used to establish your personal baseline. Subsequent sessions are scored against this individual norm on a 0-100 scale, providing a personalized performance comparison.
What are the 'Readiness Zones' in BASLN?
BASLN categorizes your cognitive performance into four Readiness Zones: 'Locked In' (90-100), 'Good to Go' (75-89), 'Off Day' (60-74), and 'Impaired' (0-59). Scoring in the 'Off Day' zone may trigger recovery protocols.
Can I track custom factors with BASLN?
Yes, BASLN allows you to define and track custom variables such as supplements, exercise, or cold plunge minutes. You can then see how these variables correlate with your cognitive readiness scores over time.
What kind of recovery recommendations does BASLN offer?
If your score falls below 75, BASLN provides evidence-ranked recovery recommendations. These may include cold exposure, bright light therapy, strategic caffeine timing, high-intensity exercise, and nap protocols, ranked by time-to-effect and evidence quality.
Is my data private with BASLN?
BASLN prioritizes privacy by collecting zero data. Your cognitive history syncs via end-to-end encrypted iCloud across your Apple devices, meaning neither Apple nor BASLN can access it. You can disable iCloud Sync for local-only storage.
What are the subscription options for BASLN?
BASLN offers a free trial with 10 full sessions. A Pro subscription unlocks unlimited sessions, full analytics, and data export. Subscription plans are available at $4.99 per month or $29.99 per year.
Does BASLN have ads?
No, BASLN does not contain advertisements. The app is free to try, with optional in-app purchases for full features, ensuring an ad-free user experience.
