Weight and dose trends
Weight by dose, protein by day, and how you felt around each shot. One chart and one plain sentence each.

Tilly is a free GLP-1 and protein tracker for iPhone and Android. Log a meal in a sentence or a photo, see how much protein is left today, and keep shots, side effects and weight in one calm journal.

Write what you ate the way you’d say it, “2 eggs and toast”, or take a photo of the plate. Tilly works out the protein, calories, carbs, fat and fiber, and shows how it got there, so you can fix anything with a note.
No searching a database. Protein comes first.
Tilly reads the plate into foods and grams, and says what it assumed.
The numbers on the packet’s label go straight in.

Eating less on a GLP-1 makes protein easy to miss. Tilly sets a daily protein target from your weight, to help you hold on to muscle, and the ring shows what’s left as you log.
No streaks and no grades, only what’s left for today.
Your dose, where it went, and a reminder on shot day.
A tap each, on the same list as your meals.

Ask Tilly about side effects, shot day or what to eat. It answers from your own journal, not a generic article, and shows every entry it read.
Every entry it looked at is a line you can open.
Nothing goes in your journal without your yes.
What to take and when stays between you and your prescriber.

Weight and dose trends, a report for your doctor, Apple Health, and reminders that know your shot day.
Weight by dose, protein by day, and how you felt around each shot. One chart and one plain sentence each.

Doses, weight, meals and side effects on one page. Share it before an appointment.

Take the picture. Tilly reads the plate into foods and grams, and lets you say what’s off.

Weigh-ins and the tape, steps, calories and sleep. Only what you switch on, one at a time.
Shot day, pill time, the evening before to take the pen out, and meals when little is logged.
English, Romanian, German and French, each written the way people talk.
No scores and no guilt. A slow week is weather, and Tilly says so.

Tilly: GLP-1 & Protein Tracker is a free app for iPhone and Android for people on GLP-1 medication such as Ozempic, Wegovy, Mounjaro and Zepbound. You log meals in a sentence, a photo or a barcode, track your daily protein, and keep shots, side effects and weight in one journal.
No. Tilly keeps your journal and explains common patterns in plain words. It never tells you what dose to take, when to take it, or whether to change anything. Those decisions are yours and your prescriber’s.
The weekly shots Ozempic, Wegovy, Mounjaro and Zepbound, and the daily tablets: the Wegovy pill and Foundayo. Tilly knows each one’s schedule and how long it stays in the body, which is what the Trends curve and the shot-day patterns are built on. Anything else, such as Rybelsus, Trulicity or Saxenda, goes in as another shot or pill and is logged the same way, without the curve.
Yes. Tilly reminds you on shot day, or at pill time for a daily tablet, and can nudge you the evening before to take the pen out of the fridge. You can turn any reminder off.
Yes. Choose “Just log my meals” when you start, and Tilly works as a food log and protein tracker. Add your medication whenever you begin.
