Usability Evaluation of the Karafs Application: A Qualitative Study Using the Think-Aloud Method.
Article in Health science reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aims: The Karafs application, a popular mobile health tool in Iran with nearly 5 million users, supports personalized diet plans, healthy cooking, and sports training. This study aimed to evaluate the usability of the Karafs application using the think-aloud method to identify user interaction challenges and enhance its effectiveness. Methods: Fifteen participants (2 men, 13 women; mean age 22 years) evaluated the Karafs application using the think-aloud method. Usability problems were identified, categorized, and assessed for severity. The evaluation process was analyzed, with an average duration of 10.58 ± 3.46 min. Results: Multiple usability issues were identified, primarily related to unclear system messages and navigation challenges. The severity of problems was classified, with most being minor but impacting user efficiency. Conclusion: The think-aloud method effectively identified usability issues in the Karafs application, providing insights for improving user experience. Addressing these issues can enhance the application's functionality and support healthier lifestyle choices.
