About this app

Notch is a simple, private log for GLP-1 injections. Record each shot, rotate injection sites, follow your weight and note side effects, all in one place. No account, no sign-up.

Works with any injectable GLP-1 medication: pick semaglutide, tirzepatide, liraglutide or dulaglutide, or type your own name.

SHOT LOG AND REMINDERS
• Log a shot in seconds: date and time, medication, dose (mg, mL or units), injection site and a note.
• The dose is filled in from your last shot, so a routine shot takes a couple of taps.
• Set your schedule as prescribed: every N days or on chosen weekdays. Home shows when your next shot is due.
• A reminder on shot day, and one the day before if you like. Tap "Log now" right in the notification.
• Starting mid-treatment? Add your past shots in one go.

INJECTION SITE ROTATION
• Pick the site on a body map: abdomen, thighs and upper arms, left and right.
• Notch highlights the least recently used site and selects it for you.
• Add your own sites, or turn off the ones you don't use.

WEIGHT AND TRENDS
• Log your weight in kg, lb or stones and pounds, and set a goal.
• See your weight line with shot days and dose changes marked, along with the change over the period and the weekly average.
• Side effects such as nausea, fatigue, heartburn or constipation, each with a severity from 1 to 5 and a note. See on which days each one was logged.
• Dose periods: your log grouped by dose, with the shots and the first and last weight of each period.
• Visit summary: your shots, doses, weight and side effects from the last 4, 8 or 12 weeks on one page. Show it at your appointment or share it as an image, made on your phone.

HISTORY
• Every record by date. Filter by shots, weight or side effects. Edit or delete, with undo.

PHONES AND TABLETS
• On tablets, in portrait and landscape, Notch shows more side by side.
• Light, dark or system theme. In English, Korean, Spanish, German, French and Brazilian Portuguese.

YOUR RECORDS STAY YOURS
• No account. Your records are saved on your phone and are not sent to us.
• Android's own backup to your Google account can include them, so they can come back on a new phone.

FREE, WITH AN OPTIONAL 24-HOUR UNLOCK
All features are free for your first 7 days. After that, logging, reminders, site rotation, your full history and the 7- and 30-day weight graphs stay free. When you want more, watch a short ad to unlock longer graph ranges, side-effect trends, dose periods and the visit summary for 24 hours (up to twice a day). A banner ad sits at the bottom of the screen.

NOT MEDICAL ADVICE
Notch is a personal log, not a medical device. It does not calculate, recommend or adjust doses, and it does not interpret your results. Always follow your healthcare provider's instructions. Notch is not affiliated with any medication maker.
