Answer a few questions about your lower back and get your Spine Severity Score, then keep a daily diary that fills itself from Apple Health.
BackSignal helps you understand your lower back and keep track of it over time.
Answer a short set of questions about your pain, movement and daily function, and BackSignal calculates your Spine Severity Score — a simple picture of where your lower back stands today. You also get a Functional Spine Age: how your spine is behaving compared with your actual age.
BackSignal is a screening, education and tracking tool. It does not provide a medical diagnosis and is not a substitute for professional medical advice, examination or treatment. Scores and suggestions are informational only.
WHAT YOU CAN DO
• Complete a guided lower-back screening in a few minutes
• See your Spine Severity Score and Functional Spine Age, and how they change
• Keep a daily spine diary — sitting, walking, exercise and sleep
• Follow guided movement videos made for lower-back care
• Learn how everyday posture, lifting and sleeping habits affect your spine
• Request a consultation with the spine team when you want to talk to someone
AUTOMATIC DAILY TRACKING
Connect Apple Health and BackSignal fills in your steps, walking distance, active minutes and sleep automatically, so your diary stays current without you typing anything. Connecting is optional — you can always enter your own numbers instead, and you can withdraw access at any time in the Health app.
BUILT AROUND THE SPINE SEVERITY SYSTEM
Your score is based on the Spine Severity System, a structured way of looking at back pain that considers pain level, leg symptoms, daily function, how long symptoms have lasted, and body measures such as BMI. Every result is saved with the answers behind it, so your history stays meaningful over time.
YOUR DATA
Your screening answers and diary entries are stored securely on servers in India, encrypted in transit and at rest. Health data read from Apple Health is used only to fill in your diary and calculate your score. We never sell your information and we never use your health data for advertising. You can delete your account and its data at any time from the Profile tab.
IF SYMPTOMS ARE SEVERE
If you have severe, worsening or unusual symptoms — including numbness, weakness, or loss of bladder or bowel control — seek medical care rather than relying on this app.
