Tongda: Chronic Pain Diary

Tongda is a chronic pain diary for people living with long-term pain — back pain, neck pain, shoulder pain, knee pain and more. Draw exactly where it hurts on a body map, and show your doctor a clear record instead of trying to remember. Built for conditions that need long-term tracking: herniated disc, sciatica, arthritis, fibromyalgia, migraine and chronic headaches. ■ KEY FEATURES ▶ Draw your pain on a body map • Mark the exact area on front and back body silhouettes • Adjust brush size to match how wide the pain spreads • Undo and clear make corrections easy • Record intensity on a 10-level scale • Paint different intensities per area, and adjust them later ▶ Detailed symptom types (about 40 expressions, or add your own) • Nerve sensations: tingling, pins and needles, burning • Muscle, bone and joint: stiff, aching, throbbing • Spreading pain: shooting down the leg, only one side hurts • Conditions: stiffer in the morning, worse at night, changes with position • Altered sensation: left-right difference, unusual feelings • Add any symptom in your own words ▶ Treatment log • Medication: painkillers, anti-inflammatories and more • Therapy: manual therapy, shockwave and more • Exercise: walking, stretching, yoga • Food: anti-inflammatory meals • Other: meditation, heat and cold packs • See how your pain changed before and after each treatment ▶ Statistics and insights • 24-hour donut chart shows your daily pain pattern • Monthly calendar heatmap makes trends visible at a glance • Trend graph reveals the long-term direction • Insights on when pain eased and when it got worse • Treatment response estimated from your own records ▶ Medical images kept with each pain • File MRI, CT and X-ray images under the condition they belong to • Sorted by the date they were taken, read from the image itself ▶ Per-pain detail view • Manage several pain areas independently • See the latest status at a glance • Compare front and back body maps side by side • Timeline of symptoms and treatments ▶ Export (PDF and backup) • PDF report: summary, body maps and full history in one document to bring to your appointment (printable too) • Encrypted backup: save everything safely and restore it anytime • Export your data whenever you want ■ PRIVACY • Your pain records stay on your device — they are never uploaded to a cloud • No sign-up and no login • Core pain logging works without an internet connection • Optional weather and ad delivery may use approximate location and an advertising identifier; see the privacy policy for details ■ WHO IT IS FOR • Anyone managing chronic pain over the long term • People who want to understand their pain patterns and triggers • Anyone who needs to describe symptoms accurately at appointments • People who want a systematic record of what actually helped ■ FROM THE DEVELOPER Tongda was built by a developer who lived with a herniated disc for years. It comes from the moments when pain was impossible to put into words, from appointments where the symptoms came out wrong, and from the frustration of not remembering which treatment actually worked. I hope it helps you on your own pain management journey. ※ Tongda is not a medical device and does not replace diagnosis or treatment.
