Because weight is not the whole picture.
If you are managing blood pressure, diabetes or anticoagulation, the calorie app and the health numbers usually live in two different places. Here they live in one, and each explains the other.
Two dials on one line
Nobody says “systolic 118, diastolic 76”. They say “118 over 76”, so that is how Loopa asks for it, two dials on one line, done in about three seconds. Readings come back labeled by the American Heart Association categories. Normal, elevated, stage 1 and stage 2, as published in Understanding Blood Pressure Readings, and the trend sits next to the week you actually ate. The World Health Organization’s sodium reduction fact sheet is why sodium is charted beside it: high-sodium diets raise blood pressure, and WHO recommends under 2,000 mg a day for adults.
Free- Systolic and diastolic on one line, as you would say it
- Every reading labeled by category, not just plotted
- Charted alongside sodium from your own food log
- iHealth cuffs sync readings automatically, on Premium

Glucose next to the meal that caused it
A glucose reading on its own is a number. A glucose reading next to the meal that preceded it is information, the American Diabetes Association’s Standards of Care in Diabetes asks for post-meal readings one to two hours after a meal begins, which is generally when the peak lands. Because food and vitals are in the same app, the chart lines them up without you exporting anything or reconciling two timestamps by hand.
Free- Fasting and post-meal readings
- Lined up against your own food log
- Trends over the last 30 days free; any range on Premium
- iHealth meters sync directly, on Premium

INR tracking, if you are on warfarin
If you are on an anticoagulant, INR is the number that governs your week, and no mainstream calorie tracker records it. Loopa does, alongside the vitamin K in your food log. The MedlinePlus entry for warfarin, from the US National Library of Medicine, is direct about why that pairing matters: foods containing vitamin K affect how warfarin works, and it asks you to “eat consistent amounts of vitamin K-containing food on a week-to-week basis”. Consistency is exactly what a food log can show.
Free- Log INR with the date and the target range you were given
- Sits alongside dietary vitamin K from your own log
- Included in the PDF report for your clinic
- The only tracker in our comparison that records it

Oxygen, heart rate, temperature and sleep
SpO2, resting heart rate, body temperature and sleep are logged the same way and charted on the same timeline. Supplements and fluids have their own trackers, and menstrual cycle tracking sits beside them so you can see how a phase lines up with weight, energy and appetite. If you just want the dates, the period calculator works them out in your browser without an account.
Free- SpO2, resting heart rate and temperature
- Sleep, with a nightly prompt on the home screen
- Supplements, with real supplement-facts data
- Cycle tracking, phase-aware, alongside everything else

A report you can actually hand over
Pick a range and Loopa produces a plain-English summary with the charts attached, exportable as a PDF. It is designed to be read by a person in a ten-minute appointment rather than to impress you with density, and it says where the data is too thin to conclude anything.
Free- 7, 30, 90 days or a range you choose
- PDF export, laid out to be read not admired
- Vitals, food, weight and activity in one document
- Explicit about what the data cannot show

Loopa is not a medical device.
It matters enough to say outside the terms of service.
Loopa records numbers you or your devices measure, and charts them. It does not diagnose anything, it does not interpret a reading as safe or unsafe, and it is not a substitute for your doctor, your pharmacist or your anticoagulation clinic. Nothing in the app is a clinical decision-support tool and nothing in it is regulated as one.
The coach is bounded the same way. It will talk about general nutrition and habits, and when a question moves toward the medical it says so and points you back at your clinician instead of improvising. That boundary is deliberate. Occasionally unhelpful beats confidently wrong about something that matters.
What Loopa is genuinely good at is the record-keeping between appointments: having the readings, the food and the dates in one place, and being able to hand over a clean PDF instead of a carrier bag of paper slips. If you are on warfarin and your clinic keeps asking what your greens intake looked like, that is the gap this fills.

Frequently Asked Questions
What people ask about tracking health past calories.
Can Loopa track blood pressure?
Yes, and it is free. Systolic and diastolic go in on one line the way you would say them out loud, each reading comes back labeled by category, and the trend charts alongside the sodium in your own food log. iHealth cuffs sync readings automatically on Premium; entering a reading yourself is always free.
Does Loopa track INR?
Yes, free, and as far as we can tell it is the only mainstream food and health tracker that does it at all. You log the value and the target range you were given, and it charts alongside the vitamin K in your food log. The MedlinePlus entry for warfarin asks people taking it to “eat consistent amounts of vitamin K-containing food on a week-to-week basis”, which is the interaction anticoagulation clinics actually ask about.
What other vitals does Loopa track?
Blood glucose, oxygen saturation, resting heart rate, body temperature and sleep, plus supplements, fluids and menstrual cycle tracking. All of it charts on the same timeline as your food and weight.
Is my health data encrypted?
Your health entries are encrypted against your own account rather than pooled in a readable table, and progress photos have no admin or coach view at all. There are no ads anywhere in Loopa on any tier, so your data is not being monetized through advertising either.
Can I give the data to my doctor?
Yes. Pick a range and export a PDF report with the charts and a plain-English summary, or export everything as CSV. It is laid out to be read in a short appointment.
Is Loopa a medical device?
No. Loopa records and charts numbers you or your devices measure. It does not diagnose, it does not tell you whether a reading is safe, and it is not a substitute for your doctor, pharmacist or clinic. The in-app coach is bounded to general nutrition and habits and points you back to a clinician for anything medical.
Is vitals tracking free?
Yes. Blood pressure, glucose, INR, SpO2 and temperature are on the free tier, for every member, on Android as well as iPhone, which as far as we can tell no other mainstream tracker does. Somebody managing a condition should not have to subscribe to write down a number their clinician asked them to write down.
