Ferritin Plus
The whole app. 7 days free.
Plus is all of Ferritin, on iPhone and Android, with one account: the iron each period costs, every plate, every lab report, on one timeline.
7 days free, then US$99 a year. Cancel before the free days end and you pay nothing.
You sign in or create an account first, so Plus works in the app with the same account. Checkout asks for a card and charges nothing today. Prices in US dollars.
What's in Plus
Everything in Ferritin,
one subscription.
- 1
It counts the iron.
Log your period the way you already do. Every logged period gets an iron estimate, so a heavy month becomes a number.
- Flow by day, from spotting to heavy
- An iron estimate for every period
- Labelled as an estimate, because it is one
- 2
It tracks the refill.
Food and supplements are logged against the loss, so you can see whether a month was covered.
- Plate check for iron meals
- Supplements logged as you take them
- Coffee and tea timed around your iron
- 3
It keeps the lab results in view.
Ferritin and haemoglobin sit on the cycle timeline, so a recheck is a date in the calendar and not something remembered at the next bout of tiredness.
- Read from a photo or PDF of your report
- Your ferritin trend against your goal
- A recheck date on the calendar
The free days
How the 7 free days work
- 01
Start free
Pick a plan and add a card at checkout. Nothing is charged today.
- 02
Use all of it
Sign in to the app with the same account and everything is there.
- 03
Keep it, or cancel
When the 7 days end, the card is charged for the plan you picked. Cancel before then from your account and you pay nothing.
Can I cancel?
Yes, any time, from your account on this site. Plus stays until the end of the period you paid for, and nothing renews after it.
Can I change plans?
Yes, from your account. A longer plan starts at once. A shorter one starts when the current period ends.
Where do I use Plus?
In the Ferritin app on iPhone and Android, signed in with the account you subscribe with.
Is the free week for everyone?
It comes with an account's first subscription. Subscribing again later starts paid.
How do I pay?
By card, on Stripe's checkout page. Ferritin never sees your card number.
