Partly
Doesn't
Not listed: we couldn't confirm it either way

From each app's App Store listing and its own website, checked November 2026. "Free" means on the app's free plan. PeptideKit's free plan covers one protocol. Privacy labels are reported by each developer and aren't verified by Apple. Features change, so check the listing before you download.

Why PeptideKit

No account, ever. There's nothing to sign up for, and your history still syncs through your own iCloud.
The shortest privacy label here. No data linked to you and no tracking. Only usage data that isn't tied to you.
Free iCloud sync across your iPhone, iPad and Mac. In the other apps here, sync is on a paid plan or not listed.
The basics on the free plan: reminders, a body map for sites, a low-stock alert, a calendar of what you took and missed, and export to CSV or PDF.

PeptideKit is a tracking and reminder tool. It doesn't suggest amounts or schedules. Follow the instructions from your healthcare provider.

Questions

You make PeptideKit. Is this fair?: We picked the things we think matter most in a tracker, so read it with that in mind. Every fact comes from each app's own App Store listing or website. Where we couldn't confirm something, we wrote "Not listed" instead of guessing.
What does "data linked to you" mean?: It comes from the privacy label on each App Store page. Data linked to you is tied to your identity, for example through an account or a device ID. Each developer fills in their own label, and Apple doesn't check it.
What's free in PeptideKit?: Reminders, the body map for sites, low-stock alerts, the calendar, iCloud sync and export to CSV or PDF, for one protocol. Plus adds more protocols and on/off cycles.
What about PeptideDeck?: It's a website with guides, calculators and a paid AI coach, not a tracking app with reminders, so it isn't in the table.
How current is this?: Checked November 2026. Apps change often, so check the App Store listing for the latest before you download.
