Your joints deserve a guide who knows
what Tuesday mornings feel like.
Flex is a pocket rheumatologist — daily micro-exercises, medication tracking, and flare-pattern logging calibrated to your specific joint type and disease stage.
I stopped cancelling plans on Tuesdays.
Score
Three checkpoints. Honest answers only.
Score yourself as you scroll. Each gap is a conversation Flex is already having with your joints.
Do you know your flare triggers?
Most people can name their pain — few can predict it.
Flare triggers in inflammatory arthritis are deeply personal. Cold weather, stress, certain foods, or even poor sleep the night before can spike synovial inflammation hours later. Without a log, you're reacting instead of preparing — and Tuesday's cancelled plans start on Sunday night.

Can you open a jar without strategy?
If you've developed workarounds, your joints are compensating.
Grip strength loss is often the first functional sign of disease progression — and the most ignored. When you start planning around your hands (running hot water first, asking someone else, waiting for a better hour), you've already lost 3–5 degrees of functional range. Micro-exercises can reverse early-stage grip loss in 6–8 weeks when done consistently.

Have you moved all affected joints today?
Rest protects. Movement heals. Most people only do one.
The instinct to protect painful joints by resting them is medically understandable — and counterproductive if sustained. Synovial fluid circulates through movement. Joints that don't move regularly become stiffer, cartilage thins faster, and the morning stiffness window extends. Twelve minutes of targeted movement, even during a mild flare, is clinically better than rest alone.

Built around how arthritis actually lives in your day.
Adaptive Micro-Exercises
Joint-specific sequences that adjust to your current pain level. Active flare? 3-minute gentle range-of-motion. Remission? 15-minute resistance protocol.
Medication Tracker
Log methotrexate, biologics, NSAIDs, and supplements. Side-effect journaling built in.
Morning Stiffness Timer
Track how long it takes to reach functional mobility each morning — a key disease activity marker your rheumatologist will notice.
Flare Prediction Engine
After 3 weeks of data, Flex surfaces your personal flare pattern — the specific combination of signals that precede your worst days.
Rheumatologist Report
Export a 3-month activity summary — pain scores, medication adherence, exercise frequency — formatted for clinic appointments.
Every score started somewhere lower.
"The methotrexate fog was real and I couldn't remember if I'd taken it. Flex's log ended three months of guessing."
"Two hours of morning stiffness was just my life. Now I know exactly which exercises get me to the kitchen in forty minutes."
"Psoriatic flares on my fingers during video calls. Flex taught me to see them coming three days out."
