You raised your dose in week nine. Five weeks later you wonder whether your curve has changed since, and you scroll through your history to find the date of the switch. You know it was roughly then, but not which day.
Medication tracking in Trendcurve takes the searching out of this. You enter your dose in mg, and every change sets a dose marker in your history automatically. With Trendcurve Pro, the "Dose steps" card also shows how fast your trend weight fell during each step.
What medication tracking does
The feature is meant for people who take a medication on a fixed weekly schedule, for example as part of a GLP-1 therapy. Trendcurve names it neutrally on purpose. The app knows no active ingredients and gives no recommendations. It only keeps the records.
It consists of four parts:
- Dose markers. Every dose change appears in your history as a marker with a date and the dose.
- Injection day and time. You choose which day your week starts on and when the reminder arrives.
- Weekly reminder. A local notification at your chosen time carries the action "Done". Once you check it off, it stays quiet until next week.
- The "Medication" card on the Today tab. It shows your next injection day and checks off the week with one tap. Only the calendar day is stored.
The label and the dose stay on your device. They never appear in notifications or on shared images, and they never go to analytics services.
How to set it up
Open "Settings & more" → "Medication tracking" and work through these steps:
- Turn medication tracking on.
- Add a label if you like. It is free text and visible only to you.
- Tap "Enter dose", type the dose in mg and switch on "Add a start date" if you want to record the step retroactively. With a start date, Trendcurve sets the first dose marker on that day. Without one, the app only remembers the current dose and creates no step.
- Pick the injection day and the time for the reminder.
- Allow notifications if your phone asks. Without permission, no reminder arrives.
At your next dose change, tap "Change dose" and enter the new value. If a marker is wrong, edit or remove it under "Settings & more" → "Experiments and markers".
An example with three steps
The numbers are invented and serve only as an illustration. Your trend weight is 98.0 kg (216.1 lb) when you start at 0.5 mg. After 4 weeks you move to 1.0 mg, and after 4 more weeks to 1.5 mg.
| Step | Dose | Duration | Trend before → after | Weekly rate |
|---|---|---|---|---|
| 1 | 0.5 mg | 4 weeks | 98.0 → 97.2 kg (216.1 → 214.3 lb) | 0.2 kg (0.4 lb) |
| 2 | 1.0 mg | 4 weeks | 97.2 → 95.6 kg (214.3 → 210.8 lb) | 0.4 kg (0.9 lb) |
| 3 | 1.5 mg | 6 weeks | 95.6 → 93.8 kg (210.8 → 206.8 lb) | 0.3 kg (0.7 lb) |
For each step, the card takes the change in your trend and divides it by the duration in weeks. In step 2 the rate is twice as high as in step 1. In step 3 it drops again although the dose is higher. That is a pattern you can observe and nothing more: the card shows what your trend did, not why.
Step 3 has many conceivable reasons: a holiday, a cold, a month of more restaurant meals, or a flatter phase without any visible cause. First check what changed in your daily life during those six weeks, and look at the chart to see whether the curve moved evenly or in jumps. A marker of the type Travel or Other under "Experiments and markers" helps you find such phases again later.
Reading dose steps in the trend
A single daily value is useless for this question. Two kilos of water can distort a whole week of any step. That is why the card works with trend weight, as described in trend weight instead of the daily value, and compares the start and end of each step on the smoothed curve.
In the history chart, the steps appear as tinted bands labeled with the dose. You see at a glance where the curve steepens and where it flattens. The "Dose steps" card sits on the Analysis tab and is visible only while medication tracking is on. For each step it shows the period, the duration, the trend change and the weekly rate.
A step runs from its marker until the day before the next one, and the current step runs until today. If you have set a target pace, you can compare each step's rate with it. Trendcurve warns you when the target pace or the measured rate lies above 1 percent of body weight per week. For help judging a weekly rate, see how fast you should lose weight.
Limits of the analysis
- Minimum data. Each step needs at least 7 days, 4 of them with a measurement. If something is missing, the card tells you how much. Short steps therefore show no rate at first.
- Correlation, not cause. If you eat differently, travel or fall ill during the same weeks, your trend moves as well. A step's rate says nothing about what triggered it.
- No comparison with others. Your rates apply to you. The app cannot judge whether a step runs faster or slower than it does for other people.
- No recommendations. Trendcurve is not a medical device. Your prescribing doctor decides on dose and intake, so discuss any unusual curve with them.
- Experiments about medication or dose. When you share an experiment result, the image says only "Experiment", never the label.
Free and Pro
Free are the switch, the label, the dose in mg, injection day and time, the dose markers in your history, the weekly reminder with "Done" and the "Medication" card on the Today tab. Pro unlocks the "Dose steps" card with period, duration, trend change and weekly rate, plus the tinted step bands in the chart. Without Pro, the markers stay visible: you can always see on which day you changed the dose and compare the curve before and after with your own eyes.
If you already take a dose, enter it today with the date you started it. The step is then created retroactively, and the analysis begins with the measurements you already have.
