From the label to the app
| What the label says | What PepLabo does with it |
|---|---|
| Missed dose: give it if the next dose is more than 48 hours away; otherwise skip it and keep the usual day [1]. | A follow-up arrives 30 minutes after a missed dose time, and Today marks the dose as overdue. PepLabo does not count the days or decide for you. |
| If 2 or more doses in a row are missed, the label describes restarting the dose escalation at a lower dosage [1]. | Today shows your last dose and how long ago it was, so a gap of several days is visible at a glance. PepLabo never changes a dose. |
| Rotate injection sites with each dose [1]. | Each log asks for the site on a front and back body map, and a weekly heat map shows which areas you used. |
| Before the cap is removed, a single-dose pen can be kept at 8–30 °C for up to 28 days [1]. | Enter the expiry date and PepLabo reminds you a week before and on the day. It does not count days since first use or days out of the fridge. |
