The countdown.
The week screen opens on the days until your next shot, with Log shot right under it. Shots can be weekly or daily. If one goes in a day early or late, the countdown moves with it and says so. A reminder arrives on shot day at the time you pick.
Injection sites.
A map of six sites: both sides of the abdomen, both thighs and both upper arms. Each shows the days since it was last used, and the one used longest ago is marked. A site you used in the last 14 days shows in amber, as a reminder of your own rotation rather than a medical rule. Nothing is blocked, and sites you do not use can be switched off. Your leaflet says which sites to use; the map records where your shots went.
Logging a shot.
As a starting point, the form fills in the site you used longest ago and the dose of your current step. Check both against your prescription and leaflet, change either, and save. You can add a photo of a site reaction. History lists every shot with its site and dose; open one to see its photo or to delete an entry logged by mistake.
Dose steps.
Type in the steps from your prescription: the dose, the date each one started and how many weeks it was planned for. Optional presets fill in common semaglutide and tirzepatide dose steps to save typing; check every entry against your prescription and change any figure. The app never moves you up a step. There is also a note for what your prescriber told you to do if a shot is missed.
Weight and side effects.
A weekly weigh-in in kilograms, pounds or stones, with an optional waist measurement. The chart shows each reading, a 7-entry average, and the change since your dose steps began and over the last four weeks. Side effects are nausea, constipation, diarrhoea, fatigue, site reaction, appetite and other, each on a five-step scale, day by day. You can also log protein and water each day.
Supply and the summary.
Pens and vials on hand, with a refill reminder worked out from the count you keep and your schedule. For U-100 syringes, a calculator converts the concentration and prescribed dose you enter into syringe units and shows the working. A PDF of the last 12 weeks for your prescriber: dose steps, shots with date, site and dose, weight and side effects.
