A supplement tracker app that logs doses from a sentence

What does a supplement tracker need to do?

Anyone who takes more than two or three supplements ends up asking the same questions. Did I take it today? What was the dose when I started the new brand? How long have I been on this one? A supplement tracker has to answer those without turning into a second job.

Sayved takes a different route from a checklist app. You don’t build a list of products first. You say what you took, or photograph the bottle, and each supplement lands in your log with a name, a dose, a unit and a time. The log grows as you use it, and you can search it later.

What do I say to log supplements?

Plain sentences, in any order, as many items as you like:

• “Took fifty milligrams of zinc and two thousand IU of D3.”
• “Five grams of creatine in my shake after training.”
• “Magnesium glycinate, 400 milligrams, before bed.”
• “Fish oil, two capsules, with lunch.”
• “Started the new iron tablets today, 14 milligrams.”

The last example is useful for later: the words “started” and “new” stay in your own transcript, which is kept exactly as you said it. When you ask “when did I start the iron tablets?”, the answer comes from that entry. Speech is converted to text on your phone, and the audio is never uploaded.

If you have a bottle in front of you, a photo of the label gives Sayved the product name and the serving printed on it. Say how much you took, or edit the entry.

Exactly which fields get stored?

For each supplement entry:

• Name of the supplement, as stated or read from the label.
• Dose as a number, and unit (mg, mcg, g, IU, capsules, scoops, and so on).
• Time, defaulting to when you logged it, editable for something you took earlier.
• Confidence that the reading matches what you meant.
• Your original words, stored verbatim, and the photo if you used one.

Every field can be edited. The correction is saved beside the first reading, never over it. A common fix is the unit: “400 milligrams” misheard as “400 micrograms” is worth a glance on the entry, because it is a thousand-fold difference. Deleting an entry removes it from the device for real.

How do I log the same stack every day?

This is where routines earn their place. Take the entry for your usual morning stack and save it as a routine. From then on, one tap logs the whole thing, one tap skips it today, and a long-press lets you change the amount, for example a double dose of one item. Nothing is filed without your tap, so the log never claims you took something you didn’t. A skip is just a skip, with no message about it.

If you want a nudge, reminders are opt-in and off by default. You write the wording and choose the times, they stay silent if you have already logged the dose, and they never say you missed anything. Details are on the one-tap routines page.

How does it show in Today, Reports, Ask and the doctor report?

• Today lists what you took, with the doses.
• Reports has a supplement roll-up that adds up each item and its doses across a week up to all time, shown together with medication. It describes what you logged. It does not compare you to a recommended amount or colour a day.
• Ask answers from your own entries: “How many days in October did I take creatine?”, “What dose of D3 was I on in the summer?” or “When did I switch magnesium brands?” It answers when asked and never volunteers anything. See ask your health history.
• Doctor report: you can include supplements in a printable report for any person and date range. That is a tidy answer to “what supplements are you on?” at an appointment. See health report for doctor.

Each family member has their own separate log, so a child’s vitamin drops don’t mix into an adult’s history. See the family health tracker page.

What about medication versus supplements?

Sayved files a prescription or a pharmacy medicine under medication and a vitamin or a sports supplement under supplements, working from what you say. They are separate categories because they are handled differently: medication is a sensitive category and is kept out of a “safe” export by default, while supplements are not. If an entry lands in the wrong place, you can change its category. The medication side is described on the medication log page.

What are the honest limits?

Sayved is a record. It cannot tell you whether a supplement is useful, whether a dose is sensible or whether two things interact, and it will not try to. If you have questions like that, they are for a pharmacist or doctor, and the log is simply something to show them.

The AI reading of voice and photos is part of Sayved Pro: 14 days free, then $2.99 a month. If you stop paying, everything you logged stays readable, searchable and exportable free forever, and you can still type entries. Your log lives on your phone, and only the text of a sentence or a downscaled photo goes to an AI model, with no name, email or account. See pricing.
