The ALDS (Ambulatory Lung Diagnostic System) combines oscillometry, FeNO, and spirometry to enable fast and comprehensive respiratory assessment. Its cloud-based algorithms evaluate measurement data alongside patient history to support the physiological interpretation of obstructive, restrictive, and inflammatory patterns. Designed for use in primary and outpatient care, the system enables efficient, non-invasive assessments within minutes and supports clinicians in the evaluation and management of respiratory conditions.

Verdict
The clearest difference is update cadence: BULO at every 3 weeks against ALDS's every 6 months. BULO also leads on iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
