Not getting enough iron, folate or vitamin B12 in your diet may cause: • Brittle nails • Fatigue • Physical weakness • Lightheadedness • Dizziness • Pallor (Pale or yellowish skin) • Shortness of breath • Headaches • Cold hands and feet *What is a Circulation Score? is a measure of how fast your blood is moving in your fingertips. A score lower than 50 indicates poor circulation. Consult your doctor. A score between 50 and 75 indicates that circulation is borderline and could be improved. A score over 75 is normal. The majority of women and men score between 75 - 100. You may notice increases and decreases with physical activity.

Verdict

The call

The clearest difference is review sentiment: Asthma Tracker゜ at 82% against Ruby Health's 23%. Asthma Tracker゜ also leads on rating (4.7 vs 4.3) and iOS requirement (13.0 vs 15.0). Ruby Health's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (2K vs 87). On price, ads, in-app purchases and monetization model there is nothing between them.
