PKU Phenylketonuria Tracks Phenylalanine (Phe), protein or exchanges
MSUD Maple Syrup Urine Disease Tracks Leucine intake and essential amino acids
TYR1 Tyrosinemia Type 1 Tracks Tyrosine intake
HCU Homocystinuria Tracks Methionine intake
IVA Isovaleric Acidemia Tracks Leucine intake

Questions

Frequently asked questions

Is Protelino free to use?
Yes. Every core feature, logging meals, scanning food and labels, tracking blood spots, and basic reports, works for free, forever, with no account required. Pro adds unlimited history, unlimited AI scans, cloud sync, and support for up to five family profiles.
Which conditions does Protelino support?
PKU (Phenylketonuria), MSUD (Maple Syrup Urine Disease), Tyrosinemia Type 1 (TYR1), Homocystinuria (HCU), and Isovaleric Acidemia (IVA), plus a general metabolic tracking mode. Each condition gets its own targets and units: Phe, Leucine, Tyrosine, Methionine, protein, or exchanges.
Does Protelino replace medical advice?
No. Protelino is a tracking and logging tool built to work alongside the targets your metabolic team has already prescribed. It never sets or changes those targets for you, and it isn't a substitute for professional medical care.
How does the AI label scan work?
Point your camera at a product's own nutrition-facts table instead of the product itself. Protelino reads the printed values, including Phe, Leucine, Tyrosine, or Methionine when a specialty product lists them, rather than estimating from a food match. Always double-check anything close to a daily limit against the packaging itself.
Is my data safe?
Your tracking data lives on your device by default. Nothing leaves your phone unless you turn on Pro sync. Pro sync is hosted in the EU and built to GDPR requirements from the ground up. See our Privacy Policy for the full detail.
Can I use Protelino for more than one child?
Yes. Free includes one profile. Pro supports up to five, each with its own condition, targets, history, and avatar. Switch between them in a tap.
Can I share reports with my dietitian or doctor?
Yes. Generate a clean PDF report of meals, nutrients, and, on Pro, blood spot trends in seconds, ready to bring to any appointment.
What happens to my data if I cancel Pro?
Nothing is ever deleted. Your full history stays safely on your device. You'll see the free tier's 10 day / 3 month view again until you resubscribe, and cloud sync pauses until then.
Which devices does Protelino work on?
iPhone and Android, including a home screen widget on both, so today's numbers are visible without opening the app.
