Levels
An estimated level curve for every compound in your stack, built from published half-lives and your own log. Each compound gets its own chart.

Know your
levels.
Vantal logs every dose in one tap, charts the estimated level of each compound, reads your bloodwork and tracks your training, all on one private timeline.
iPhone and Android coming soon. No account needed. Free for the first 50 users.
One timeline
Everything you take, measure and lift, together.
Most apps track one thing. Vantal puts your doses, your levels, your labs and your training on the same axis, so you can see how they move together.
Labs
Snap a photo or PDF of your report. Vantal reads the values, you check them, and every marker is charted against your doses with its reference range.
Training
Workouts, sets and progression. Your strength trend sits right next to your levels and your labs.
Fuel
Weight, body measurements and nutrition targets, with context that knows when your dose changed, so a water shift isn't mistaken for a trend.
Honest estimates
A curve you can trust, because it tells you what it doesn't know.
Every level in Vantal is labelled as an estimate. The model is published in the app, uncertainty is drawn as a band, and where no half-life has been published, Vantal draws no curve at all.
- ✓Calibrate to a blood test. Link a curve to a lab result and Vantal scales the estimate to your measured level.
- ✓Measured, modelled, projected. One clear visual grammar, so you always know which is which.
- ✓Never a dose suggestion. Vantal records what you enter. It doesn't tell you what to take.

Private by design
Your data lives on your phone. Not on ours.
No account. No ads. No analytics. No trackers. Health data is the most personal data there is, and we built Vantal so we never have to hold it.
On-device first
Everything is stored locally and backed up on the device, with verified snapshots. Nothing leaves without you asking.
Encrypted sync
Optional sync is end-to-end encrypted with a key only you hold. We store ciphertext we can't read.
Ask before sending
Lab scans and questions leave your phone only when you tap, after a clear consent screen. Our server keeps none of it; the AI provider that reads them may hold them briefly under its own terms.
FAQ
Questions, answered plainly.
What can I track?
GLP-1 medications, testosterone and other hormones, peptides and ancillaries: anything you take on a schedule. Vantal also covers your bloodwork, workouts, weight, body measurements, nutrition and data from Apple Health or Health Connect.
Is Vantal medical advice?
No. Vantal is a personal log and visualisation tool. It is not a medical device. It does not diagnose, treat, cure or prevent any condition, and it never recommends doses. Talk to your clinician about your treatment.
How accurate are the level curves?
They are estimates from published pharmacokinetic data and the doses you log, and real levels vary from person to person. Vantal shows an uncertainty band, publishes its model in the app, and lets you calibrate a curve to your own lab result.
Do I need an account?
No. Open the app and start logging. If you want your data on a second device, turn on encrypted sync and keep your recovery key.
What does it cost?
Vantal is free for the first 50 people who join. After that it costs $4.99 a week, $9.99 a month or $39.99 a year. There will never be ads, blurred bait features or surprise trial billing.
Which platforms?
iPhone, Android and the web, from one app. The web version works today at app.vantal.app and installs to your home screen.
