Everything about your hip replacement. Before, during, and after. Mend is a calm, private companion that carries you from "surgery scheduled" through fully recovered. It organizes the instructions your surgeon already gave you — then turns your recovery into visible, day-by-day progress. BEFORE SURGERY • A T-minus countdown anchored to your surgery date • The prep checklist hospitals hand out as a 40-page booklet — as gentle reminders that arrive on time • The high-stakes items patients forget: NSAID and supplement stop dates, dental clearance, fasting instructions • Home preparation: fall hazards, recovery station, equipment, your 2-week helper • Prehab exercises with streaks — strengthening before surgery measurably improves recovery AFTER SURGERY • A 30-second daily check-in: pain, swelling, mood, walking aid, incision photo • A milestone timeline from first steps to full stride — walker to cane to driving to "back to normal" • Precaution cards matched to your surgical approach (posterior or anterior) • Med reminders with taper support — taking less than prescribed is celebrated, not just logged • Red-flag awareness: the symptoms that mean "call your surgeon now" PT EXERCISES, DONE RIGHT • The standard hip-replacement exercise program, built in — every exercise illustrated and explained • Configure sets, reps, and sessions per day to match exactly what your PT prescribed • Session reminders, daily progress, and streaks that keep you honest THE SURGEON REPORT One tap builds a clean PDF: pain trend, medication taper, walking-aid progression, exercise compliance, milestones, and your notes. Hand it to your surgeon or PT at follow-up — and answer "am I recovering normally?" with data. PRIVATE BY DESIGN No account. No cloud. No tracking. Your health data never leaves your iPhone. ONE PURCHASE, YOURS FOR GOOD Recovery is a season, not a subscription. Try everything free for 3 days, then one purchase unlocks Mend for good. Mend is an organizer and logbook for your care team's instructions — general educational information compiled from published hospital protocols, not medical advice or a medical device. Every default is editable, and your surgeon's instructions always come first. Terms of service: https://www.orionsoftware.co/terms Privacy Policy: https://www.orionsoftware.co/privacy
