What the progress tracker does
Most weight-loss apps show you a single number on a single day. Retatrutide users need more: a steady-state PK curve, the dose escalation history that produced it, side effects clustered around dose-change weeks, and weight movement that lags injection by 7–14 days. The Retadose progress tracker fuses all four into one view at /app/trends, plus a milestone tracker and shareable progress link.
Milestone trophy cards
Every Retadose account auto-unlocks milestone trophies as you cross thresholds: 5%, 10%, 15%, 20% (and every further 5%) of body weight lost, your first inch off the waist and every 2 inches after, a 30-day check-in streak, and your first personal PK calibration. Trophies are measured from your starting weight, which you can set if you began treatment before joining, and they stay on your Milestones page as an at-a-glance record of progress that survives bad weeks.
Persistence is the largest predictor of GLP-1 outcomes. A 2024 retrospective analysis (PMC12636059) found that users who maintained injection consistency through month 3 lost roughly twice as much weight at month 12 as users who let gaps creep in. Visible milestones reinforce the streak.
The multi-metric chart
The trends chart at /app/trends overlays four signals on a single time axis:
- Weight — every weigh-in plotted as a dot, with a 7-day moving average line.
- Modeled level — your estimated retatrutide blood concentration from the PK engine, updated every dose and decay-modeled between doses.
- Doses — vertical markers showing each injection with its dose in mg.
- Side-effect intensity — daily check-in scores aggregated to a 0–10 daily band.
The visual gives you a fast read on cause and effect: did the bump in nausea track to a dose escalation? Did the weight stall coincide with a level plateau, or did it precede one? Did skipping a week drop your modeled level into a sub-therapeutic window?
Sharing your progress
Each trophy card gets its own link at /share/<token>. The link is unguessable and needs no login, and it shows only the card image and milestone headline, with previews that render inline on Reddit, X, Bluesky and SMS. Your name appears on the card only if you opt in from Settings.
For a clinician, use the Provider Summary (Dashboard → Provider Report): your last 90 days of doses, check-ins, weight and waist, reported side effects, wearable data and glucose on one page. Print it or save it as a PDF to bring to a 10-minute appointment.
How it compares to spreadsheets and weight apps
| Capability | Spreadsheet | Weight app | Retadose tracker |
|---|---|---|---|
| Weight log | Manual | Yes | Yes |
| Dose log with dose math | Manual formulas | No | Yes (auto) |
| PK level estimate | No | No | Yes (Coskun 2022 params) |
| Side-effect tracking | Manual | Sometimes | Daily check-in |
| Milestone trophies | No | Sometimes | Yes |
| Clinician-ready summary | Email file | Rarely | Printable PDF + CSV |
Privacy and data control
Retadose stores your data on a single server you can revoke access to. We do not sell, broker, or share your dose or weight data. Trophy share links expose only the card, never your account, dose log, vials, or contact info. You can delete your account and all stored data at any time from settings.
Frequently asked questions
Can I export my progress as CSV or PDF?
Yes. The Provider Summary on your dashboard lists your last 90 days of doses, check-ins, weight and waist, side effects, wearable data and glucose, and prints or saves as a PDF. A CSV download covers your doses, check-ins with your modeled level, wearable data and glucose, for a personal backup or a clinician who prefers spreadsheets.
Is a trophy share link permanent?
It lasts as long as the trophy does. Deleting your account removes your trophies and their links. If you correct a mistyped entry and the corrected data shows a trophy was never earned, that trophy and its link are removed too.
How are milestones triggered?
Milestones are pure functions of your logged data: weight change from your starting weight, waist change from your first measurement, consecutive check-in days, and your first PK calibration. Nothing is unlocked manually. They appear automatically when you cross the threshold, and if you correct a mistyped entry, your trophies are re-checked against the corrected data.
What if I miss a check-in?
The streak counts active days, but the side-effect chart simply has a gap. The dose log and modeled level are unaffected — they update whenever you log an injection. Missing a check-in won't break milestones you've already unlocked.
