The best steroid cycle tracker apps in 2026

OptiPin – a cycle as a unit, with labs on the timeline

OptiPin added dedicated cycle tracking in July 2026. You group a run's compounds into a named, dated cycle. The cycle then gets a week-by-week timeline with one lane per compound, your dose ticks and your blood draws marked on it. Phase tags for blast, cruise and PCT sit on the same timeline, so you can see which phase each blood panel was drawn in. A phase-aware bloodwork checklist marks off baseline, mid-run, end-of-run and recovery panels as you log them. Repeating on/off schedules have been supported since August 2026.

Two features are estimates. We would rather be blunt about that. The estimated clearance window is worked out from each compound's half-life and your last logged dose (roughly three to five half-lives of the slowest-clearing compound). It is a model rather than a measurement. It is not a start date for anything. The level chart puts every compound you log on one screen, with nandrolone, trenbolone, masteron, boldenone, primobolan and the common orals shown as estimated amount on board. The half-life figures behind it are the same ones in our free half-life visualizer. When a cycle closes, OptiPin keeps an archive: compound totals, lab movement from first to last panel, weight change and logged side effects. You can export it as a plain report. Phase tags also give OptiPin's AI insight summaries the context of which phase you were in.

There is no account and the data stays on your phone. iCloud Sync across your own Apple devices is optional. Progress photos never sync or leave the device.

Where it falls short: iPhone only. It is also a general tracker that covers TRT, peptides and GLP-1s, so a lot of the app is not about cycles. It does not ship cycle templates. It will not tell you what to run.

Best for: anyone who wants a cycle's doses, labs and phases in one record they can look back on, or hand to a doctor. Get OptiPin on the App Store →

Since September 2026 it also reads your Apple Watch nights (or Whoop, Oura or Garmin data in Apple Health) into a nightly recovery score scored against your own last 60 nights. Health Trends then compares recovery on mornings after injection days with other mornings. It also compares HRV and sleeping heart rate in weeks on each compound against weeks off. None of the other cycle trackers here reads wearable data.

Anabolic Steroid & TRT Tracker – the most-reviewed dedicated log

This is the app most people find first. At 74 US ratings (4.7) it has the largest review base of any cycle-specific tracker. It logs every dose by compound, amount, time and method across steroids, TRT, peptides and SARMs. It counts what is left in each vial, recommends the best-rested injection site and estimates the active amount of each compound from half-lives you enter. Weight, blood pressure, sleep, mood and custom metrics sit alongside. At $24.99 a year it is also one of the cheapest subscriptions here.

Where it falls short: no phase tags or cycle grouping that we could find. Bloodwork is a general health-metric log rather than a lab timeline. It was last updated in April 2026.

Best for: a straightforward dose journal at a low price.

Dosely – inventory and photos first

Dosely (EFN Group) pitches itself as a "peptide and steroid companion". Its strengths are on the supply side: vial inventory with a reconstitution calculator, AI vial scanning from a photo, a cost estimator and a 50+ compound database with half-lives. It also has a progress photo journal with side-by-side comparison, a cycle manager for organizing phases and a doctor export.

Where it falls short: a subscription is required to use the core features. Its listing also shows several different prices at once. Its half-life curves are models kept separate from measured levels. It does not estimate a clearance window.

Best for: people who mainly want stock, cost and photos organized.

TRT Plus – one-off price, enhanced mode

TRT Plus has two modes: Classic for plain TRT and Advanced for enhanced stacks. It ships 100+ pre-configured compounds including anabolics, orals, SARMs and ancillaries. Its listing claims a multi-route PK model, titration plans, photo scanning of lab reports with an AI bloodwork report and level predictions anchored to your own bloodwork. It is sold as a $29.99 one-off lifetime purchase and runs on iOS and Android.

Where it falls short: 4.0 from 19 US ratings. Its listing also leans on proprietary branded models we could not check independently.

Best for: Android users and anyone who would rather pay once.

Cycle: Anabolic & TRT Tracker – new, clean, unproven

Cycle launched at the end of July 2026 and had no US ratings when we checked. It logs doses, labs, weight, blood pressure and symptoms through a daily checklist, draws a half-life decay curve per compound and scores your consistency. Data is stored locally by default. Signing in adds cloud sync. Pro is $7.99 a month or $49.99 a year.

Best for: worth a look if you like its design. Too new to judge.

Steroid Plotter – a free web tool, not a tracker

Steroid Plotter is a free website that plots estimated blood levels from doses and half-lives you type in. Its site says about 20,000 people use it each month. It is good at showing how esters stack and decay. It does not remember what you actually took and has no reminders or bloodwork. The curves are only as good as the half-life numbers behind them. Its example protocols are not a recommendation from anyone, including us.

How to choose

If you only want a record of doses and vials, the Anabolic Steroid & TRT Tracker is cheap and does that. If you want the cycle as a whole (phases, labs and doses on one timeline plus an archive to compare the next run against) that is what OptiPin is built around. On Android, TRT Plus and Dosely are the realistic options. Whatever you pick, the app matters less than the bloodwork it holds: a baseline before, a panel during and a recovery panel after, read with a clinician.

Frequently asked questions

What is the best app to track a steroid cycle?

No dedicated cycle tracker here has more than 74 US ratings, so nothing is proven yet. Anabolic Steroid & TRT Tracker is the most-reviewed dedicated option and the simplest. OptiPin goes furthest on structure, with phase tags, a lab timeline and an estimated clearance window. TRT Plus is the one-off-price option. TRT Plus and Dosely both run on Android. Steroid Plotter plots levels but does not log.

Can an app tell me when my cycle has cleared?

Some apps estimate it from half-lives. OptiPin estimates a clearance window from each compound's half-life and your logged doses. Anabolic Steroid & TRT Tracker estimates the active amount of each compound from half-lives you enter. These are rough models. They measure nothing and are not a signal to start or stop any medication. Bloodwork and a clinician are how recovery is actually checked. Our guide to how a cycle is structured covers which labs matter.

Which steroid cycle tracker keeps data private?

OptiPin needs no account and stores data on your phone, with optional iCloud Sync across your own Apple devices. Cycle stores data locally by default and only syncs if you sign in. The App Store privacy labels for Anabolic Steroid & TRT Tracker and TRT Plus say “Data Not Collected”. Dosely's label lists purchases, contact info, identifiers and usage data as data used to track you. Check each label before logging anything you would not want tied to your email.
