## What is Renabook?

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.

### 4/5 — 良い

*2026-10-14*

他のアプリとデータがリンクしてくれると助かる。

**Developer response:** benefitNO1様

★4と「良い」のお言葉、ありがとうございます。

「他のアプリとデータがリンクしてくれると助かる」とのご要望、私たちも大切なことだと考えています。今のところ、このアプリの記録はこの端末の中だけに保存していて、他のアプリと自動でデータをやり取りする機能はありません。そこで、iPhoneの「ヘルスケア」と、体重と血圧の記録をつなげられるように対応いたします。できあがりましたら、アップデートでお届けします。

それまでの間は、「グラフ」タブのいちばん下にある「先生に見せる」から、「計測記録CSV」「検査値CSV」を書き出せます（Pro）。CSVはExcelやNumbersなどの表計算アプリで開けます。

ヘルスケアのほかに、特につなげたいアプリがありましたら、設定の「不具合・バグ報告・ご要望」からお聞かせください。
