Features

What PEPTIDAL does

Grouped by what you are trying to do. Each feature says whether it is free or Premium. Tracking and information only, not medical advice.

Track

Free, with limits

Your stack

One list for the peptides, medicines and supplements you take. Add from the library or type your own name. Free accounts can track one peptide or medicine and up to five supplements.

Free

Logging

Log each time you take something from the Today screen, or skip it. Your history is kept in your account.

Free

Reminders

Dose reminders are scheduled on your device at the times you set. You need to allow notifications. There is also an optional weekly reminder for the letter.

Free, longer history Premium

Daily check-in

Four quick taps for energy, mood, sleep and appetite, with nausea as an optional extra. Skip anything you like. Free accounts see 30 days of history.

Free, longer history Premium

Sessions

Simple timers for things like fasting, sauna, cold and red light, so you can keep a record. Free accounts see 30 days of history.

Premium

Unlimited items

Track as many peptides, medicines and supplements as you like.

Understand

Free

Calculator

Converts numbers you type in, for example the amount in a vial, the liquid added and the amount you have already decided on, into a reading you can check. It works either way round. It does not recommend anything and it does not know what is right for you. You can save a vial from the calculator to keep an inventory.

Free

Body, sleep and lab trends

Record weight, body measurements and sleep, and see simple charts of your own history, with markers for when you logged something. Lab results sit on the same timeline.

Premium

Lab detail

The latest value and direction of each lab marker are free. Premium adds the full history, charts and the change since the previous result.

Free

Estimated level curve

For items with a published half-life, the Today screen can draw a simple estimate of how much may remain over time, labelled as an estimate and not a clinical model. For other items it shows an illustrative shape only.

Free, longer history Premium

Apple Health and Health Connect

If you allow it, you can tap sync in Settings to bring in sleep, weight, body fat percentage and lean body mass, plus heart rate variability (HRV), resting heart rate and VO2 max, which appear in the Recovery section of Insights exactly as recorded, with no interpretation. Apple records HRV as SDNN and Android as RMSSD, so they are labelled and never compared. It reads only and never writes. What you type yourself is never overwritten. Free accounts see 30 days of readings, and Premium shows longer history.

Premium

Clinician summary

Builds a PDF of your protocols, labs, body measures and check-ins on your device, to share with a clinician if you choose.

Learn

Free

The library

Plain descriptions of items people track, each with an evidence label, a regulatory status label with a date, and sources. No doses and no recommended amounts. How the library is built.

Free, older issues Premium

Weekly letter

A short weekly summary of published studies, the same for every reader and approved by a named person before publishing. The latest four issues are free to read in full. Older issues are Premium, except safety and regulatory items and corrections, which stay open to everyone. How we choose studies.

Ask AL

Free, optional

AL, an optional AI assistant

Ask general questions about what you read and log. AL can use what you have logged only if you agree on a consent screen first. It is an AI, not a doctor, it can get things wrong, and it does not give personal dosing advice. More about AL.

Free

Report this reply

Every AL reply has a Report this reply button, so you can tell us when something looks wrong.
