The units come from your vial’s lab sheet. One tap logs the dose. A reminder brings the next. Free, forever.
No mockups and nothing staged — this is the app as it ships.
Tide or Rose. Your colour.
Tap one — this page changes too. Same app, same lab-measured math, and you can switch it any time.
Research vials rarely contain exactly what the label says. goodtides keeps a registry of 3,500 third-party lab reports (COAs) published across 72 vendors — connect yours by lot number, and the math follows the lab’s measured mg for that lot.

goodtides’ own catalog of 100+ markers with reference bands narrower than standard lab ranges, resolved to your age and sex, trended over time, and cross-read against the protocol you actually run — for context and trending, not diagnosis. Cycle-dependent hormones (estradiol, progesterone, LH, FSH) need a cycle day to read honestly, so they show unscored, with the draw that would score them.
A push before every scheduled dose, named by peptide. Pick your lead time; one you've already logged won't nag, and if you miss the slot, a catch-up nudge still has your back.
Vial mg + BAC water become the exact units to draw, on a syringe you can drag. Injectable or oral.
Every trackable peptide and blend — commonly cited research dose tiers, frequency, timing, route and cycle notes, for reference.
Doses computed from the lab-measured mg for your lot, not the label — 3,500 COAs from 72 vendors on file, matched by lot number.
Upload a lab PDF, confirm the markers it reads, then track them against reference ranges over time.
Every dose on a per-peptide month and year heatmap, today ringed, each peptide its own color, tinted by how you felt.
Rate each dose and tag effects. A 7-day trend shows how you’ve been feeling.
Records the spot you log, with a chart so you can spread your sites out.
Track multiple open vials with a draw-from switch; wipes, needles and BAC water count down as you go.
Forecasts your empty date from your real dose log, so you can restock in time.
Finished vials roll into a per-peptide ledger that nudges your next cycle on time.
A welcome walkthrough, a guided tour, and a paced how-to-inject demo get you going on day one.
A reconstitution guide shows the exact BAC-water fill before you draw — no mixing math at the counter.
Most tracked peptides carry mechanism, safety notes and research references — learn it before you log it.
Educational starting-point templates from the research literature, cross-referenced with your tracked markers. Built to review with a licensed provider — never a prescription.
Local-first and offline — your log lives on your device, and we can't read it. Create a free account to back it up and sync across devices; export to CSV or JSON anytime.
Already track in a spreadsheet? Upload .xlsx or .csv and we import past doses, skipping duplicates.
Forgot to log? A gentle prompt catches up doses from the last few days, and "catch me up" backfills finished vials so your history stays whole.
Optionally log your weight in lb or kg, backdate entries, and watch the trend on a full chart with BMI. A private log, yours alone.
Keep a logging streak and share a streak, regimen, or history card. Your numbers only.

On iPhone, download it from the App Store. Everywhere else, Companion runs as a web app — add it to your home screen once and it opens full screen and offline, just the same.
Same app, same account — your data syncs across both.
What it is: a tracker and a calculator. It records what you enter (protocols, doses, injections, vials, supplies, schedules) and does the arithmetic of turning vial mg and water mL into syringe units. Catalog dosages shown alongside peptides are commonly cited research figures, included as a reference.
What it isn't: a medical service. goodtides does not provide medical care, evaluate your condition, or advise on individual dosing. Protocol drafts are educational summaries of published research figures, not individualized advice. COAs shown in the app are third-party lab reports published by vendors; goodtides does not test vials and cannot certify any vial’s purity, identity, or safety — COA-adjusted math only changes the arithmetic to the lab’s measured mg for that lot. Bloodwork bands are informational reference ranges for trending, not a diagnosis. Peptides are research compounds, not FDA-approved drugs. Decisions about whether and how you use them are your own. Consult a licensed provider before starting, adjusting, or combining any protocol.
