Track 3 peptides free, forever — no account needed. Pro unlocks custom alert thresholds, unlimited items, restock history, and CSV export.
Track your peptides and supplements without a spreadsheet. Start free — no account, no ads, no tracking. Stackr tells you when to reorder, factoring in shipping time, so you never run out.
FREE TO START
Track up to 3 items free. No account required. Your data stays on your device.
NEVER RUN OUT

• Restock history and reorder logging
NEVER OVERPAY
• Cost per use, daily spend, and annual run-rate

CONCENTRATION

• Every number is one you typed. Stackr never suggests an amount or works one out.
SCHEDULES THAT MATCH REAL LIFE

Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
Amounts shown as you entered them: amounts in IU now show in IU on every screen, and an amount like 1.25 mg reads 1.25 mg instead of being rounded to 1.3. Home and your protocol show the amount for today's schedule phase, which is the amount Stackr records when you log. The summary PDF prints the amounts you entered and logged the same way. Nothing you saved has changed.
Steadier item edits: oil items take amounts in mg or mcg, to match the mg/mL on their label, and switching an item from oil to powder now clears its old mg/mL value.
If you're coming from an earlier version, this release also brings everything from 1.5.0:
• Back up your stack: a full copy of your data, kept on this phone and never copied to iCloud
• A one-tap summary PDF of your items and the last 90 days, for your doctor
• Calmer notifications: one message at your reminder time instead of one per item
• Log a dose from any item, even unscheduled ones
• Concentration: record the value printed on your product's label
• Sources & References for the app's health-related statements
• Better VoiceOver support and easier-to-hit buttons
