Review momentum
57/100
faster than 61% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Renabook: Renal Dialysis Diary
Your paper dialysis book, all in one place.
Renabook is a simple log for life on dialysis: weight and blood pressure morning and evening, and the fluid removed on dialysis days. No sign-up. No ads. Your records stay on your device.
■ Cards that match the day
On dialysis days you record pre- and post-dialysis weight and the fluid removed. On other days, weight and blood pressure morning and evening. Set your dialysis days once and today's cards line up for you.
■ The difference from your dry weight, as a number
Enter the DW your doctor gave you and the weight card shows the difference. It makes no judgement and gives no warnings — the number is yours to take to your clinic.
■ Charts and a two-week table
Weight, blood pressure, and lab values become charts. The last two weeks appear in the same table layout as a paper dialysis book.
■ Works with Apple Health (free)
Weight and blood pressure that your scale or blood pressure monitor app saves to the Health app are filled into the morning and evening entries on non-dialysis days. The weight and blood pressure you record here are written to Health as well. Values you entered by hand are never overwritten. Turn it on anytime under “Link with Health” in Settings.
■ One page for your clinic
Hand over your records as a clinic summary (PDF). CSV export is included.
■ An emergency and travel card
Keep your treatment settings — access, dialyzer, blood flow rate, session length — on a card you can show staff at another unit, in large text, even with no signal.
■ Reminders that know your schedule
Measurement reminders morning and evening, and a reminder the night before a dialysis day. No measurement reminders on dialysis days, since you are measured at the unit.
Free: daily measurements, linking with Apple Health, the access check, lab values, one emergency card, and the last 90 days of the charts
Pro (a one-time purchase, no subscription): the clinic PDF, CSV export, the full chart history, and managing other people
Note: this app is a log and reminder for life on dialysis. It is not a dialysis record book issued by a medical provider, and it does not diagnose, treat, or provide medical advice. Always talk to the doctors and staff at your clinic about your weight, your blood pressure, and your treatment.
