Act one · the problem
A 30‑second daily check‑in becomes a dose history, nine insights computed on your iPhone, and a five‑page report for your next appointment. No account. No cloud.
One email at launch · 7‑day free trial · $4.99/mo or $29.99/yr · iPhone, iOS 17+
Three questions the scale can’t answer
The scale drops either way. Rapid weight loss on a GLP‑1 takes lean mass with it unless protein and training keep up, and a bathroom scale can’t tell you which is which.
Navy‑method lean mass, measured weekly, trended over time.
Day 0 and day 1 hit differently from day 4. Most people learn their window by feel, badly, over months.
Energy and side‑effect severity per day since injection, across your last cycles.
“I felt rough for a while after the last increase” is not data. Your prescriber is deciding your next dose on it anyway.
A five‑page PDF: weight with dose markers, side effects by phase, dose history.
Act two · the protocol
Three things the app records that no calorie counter does. Shown here at full width, because a dose ladder crammed into a phone frame is unreadable at 6pt.
Dose history · tirzepatide · every step you have actually taken
Training calendar · August 2026 · injection day and the days after
Injection dayDays after
Your injection day, and the three days after it. DOSE marks them from the day you told it you inject, so the pattern is visible on a calendar instead of remembered.
An injection‑day alert at 8:00 AM on your day, naming the medication. A daily reminder at a time you pick. Both are local notifications — there is no push server.
Where your energy actually runs highest across the cycle, compared between the 48 hours after an injection and the days further out — reported once you have logged at least four cycles.
Body composition · U.S. Navy method · computed on device
BF%♂ = 86.010 · log₁₀(waist − neck) − 70.041 · log₁₀(height) + 36.76
BF%♀ = 163.205 · log₁₀(waist + hip − neck) − 97.684 · log₁₀(height) − 78.387
lean mass = weight × (1 − BF ÷ 100) · protein target = 1 g per lb of lean mass
Act three · the handover
Five pages, rendered on your iPhone with Apple’s own PDF renderer. It never touches a server, and it is built to be read in sixty seconds across a desk.
Act four · the engine, the price, the promise
Plain arithmetic over your own logs. Each check has a data threshold and says nothing until it is met — no pattern, no card. The copy below is what the app actually shows.
| Number | Check | What it says | Fires at |
|---|---|---|---|
| 01 | Post‑Injection Pattern | In your logs, side effects peak on day 0 post‑injection and ease by day 3. | n ≥ 3 cycles · peak ≥ 2.0 · peak ≥ 1.5 clear of other days |
| 02 | Dose Adaptation | Your avg side effects at 7.5mg are 47% lower than at 5mg. | ≥ 7 days at the current dose |
| 03 | Hydration and Nausea | Days under 64 oz of water show 1.6 points higher nausea in your logs — on injection days and other days alike. | ≥ 5 days per group · ≥ 1.0 delta · injection‑day controlled |
| 04 | Protein Intake | You’re averaging 87g protein/day (target: 172g). That leaves you 85g short each day. Injection days average 61g vs 91g on other days. | 14‑day average vs lean‑mass target · injection‑day gap shown at ≥ 15 g |
| 05 | Weight Trend | Averaging 0.8 lbs/week over this window. 27.1 lbs to go to your goal of 195.0 lbs. | 7‑day moving averages · n ≥ 10 · rate ≥ 0.5 lb/week |
| 06 | Injection Sites | Left Abdomen used 63% of the time; Right Thigh least often. Follow the rotation guidance that came with your medication. | last 10 injections · n ≥ 8 · one site > 50% |
| 07 | Body Composition | ~172-174 lbs lean mass. Lean mass is holding steady in your measurements. | 3+ measurements · direction claimed only at ≥ 2.5 lb |
| 08 | Energy Pattern | Your energy runs 67% lower (and side effects higher) within 48hrs of injection. It runs highest on days 5-6. | ≥ 4 injection cycles · gap ≥ 20% |
| 09 | Lean Mass Protein Target | You need 172g protein to protect 172 lbs of lean mass. You’re averaging 87g (85g gap). | needs body composition + 5 protein entries |
When each check first appears · verified against a realistic history, weekly injections
Eight of the nine arrive inside a month. The ninth waits for eight injections, because a claim about which site you overuse means nothing before then — it used to appear on day 25 and was wrong most of the time. A test in the app fails if any check stops being reachable, and every check that claims a pattern is run against thousands of histories built from pure noise and fails if it speaks up too often: a flat week has to produce silence, not an invented trend.
Insights describe patterns in your own logs. They are not medical advice — review dose decisions with your prescriber. That sentence sits under the list in the app, too.
Data Not Collected · the App Store label, not a slogan
Your logs live in your iPhone’s storage and go nowhere unless you tap Share. Not us, not an insurer, not an employer. Read the full policy →
APP PRIVACY · DATA NOT COLLECTED
Nothing to sign up for, nothing to reset. Delete every entry from Settings in two taps and the app returns to day one.
Insights, the PDF and the CSV are computed and rendered on the phone. There is no backend to go down or get breached.
No analytics, no crash reporters, no ad frameworks. Billing runs through Apple’s StoreKit; we see a subscription status and nothing more.
Reads weight, steps, sleep and workouts to pre‑fill your log. Writes weight back only when you edit it. Decline it and everything still works with manual entry.
Price
DOSE Pro unlocks new entries and the insights that depend on them. Everything you have already logged — and both exports — stays readable forever, subscribed or not.
Read‑only never expires. Cancel and your logs, the PDF report and the CSV export remain available. The subscription gates new entries, not your history.
Billed by Apple to your Apple ID. Manage or cancel in Settings → Apple ID → Subscriptions. Renews automatically unless cancelled at least 24 hours before the period ends.
Price shown in USD; local pricing is set by Apple’s tier equivalents in your storefront.
Questions
Ozempic, Wegovy, Mounjaro, Zepbound, and compounded semaglutide and tirzepatide — each with its own dose ladder, so the steps you record are the right ones for your medication. DOSE records the dose your clinician prescribed; it does not propose a schedule or suggest when to change.
$4.99 per month or $29.99 per year, both with a 7-day free trial. Billing is handled by Apple; cancel any time in your iPhone's Settings → Apple ID → Subscriptions.
Nothing is lost. DOSE switches to read-only: you can still open every past entry and export the PDF report or the CSV. The subscription unlocks creating new entries and the insights that depend on them.
Yes. Apple Health is optional. If you allow it, DOSE reads weight, steps, sleep and workouts to pre-fill your log and writes weight back only when you edit it. Decline it and you enter weight manually; everything else is identical.
On your iPhone, in the app's local database. DOSE has no servers, no accounts, and no third-party SDKs, so there is nothing for us to see. The only time data leaves the device is when you tap Share on a PDF or CSV.
You enter waist and neck circumference weekly (plus hip, for women). DOSE applies the U.S. Navy method to estimate body-fat percentage and derives lean mass from your weight. It is not a DEXA scan, but it is consistent, trackable, and computed the same way every week.
Five pages: a patient summary, your weight chart with dose-change markers, a side-effect timeline, protein and hydration compliance, and your full dose history. It is rendered on the phone and shared through the iOS share sheet — email, AirDrop, print.
No. DOSE is a tracking tool, not a medical device. It does not diagnose, treat, cure or prevent any condition, and insights describe patterns in your own logs only. Discuss any dose or protocol change with your prescriber.
iPhone running iOS 17 or later, with a Home Screen widget. There is no Android or iPad-native version yet.
