These two apps take opposite editorial stances. PeptIQ is a broad peptide-tracking app with a dosing-and-stacking library, protocol templates, AI features, a community, and versions for iOS, Android and web. Pepti is a deliberately narrow, measurement-only tool for iPhone that publishes no dosing content, keeps everything on the device, and has no account. The deciding question is whether you want an app that supplies dosing information, or one that refuses to.

This comparison is written by the maker of Pepti, one of the two apps. The PeptIQ facts below are taken from its own website and App Store listing as read in October 2026, and each is dated and linked in the Sources section so you can check it yourself. Where a common assumption turned out to be wrong on checking, we have said so rather than repeat it.
| Pepti | PeptIQ | |
|---|---|---|
| Approach | Measurement & record-keeping only; no dosing content | Broad tracker with a dosing/stacking library, protocol templates and AI (Oct 2026) |
| Platforms | iOS 17.2+ | iOS, Android and web (Oct 2026) |
| Price | $16.99/mo or $69.99/yr USD, 14-day free trial on annual; one tier | Free to download; in-app purchases listed from $9.99 to $129.99 (App Store, Oct 2026) |
| Account & data | No account, no cloud sync; data on-device, apart from optional AI coach chats | No account required for basic use; data local by default; optional account + cloud sync on Premium (Oct 2026) |
| Dosing content | None, by design | Yes — dosing and stacking library, dosing-schedule and protocol templates (Oct 2026) |
| Reconstitution math | Yes; vial + diluent to draw volume and U-100 units | Yes; reconstitution calculator incl. multi-peptide blends (Oct 2026) |
| Injection site rotation | Yes, 12-site | Yes; injection site map (Oct 2026) |
| AI features | Optional AI coach chat only | AI companion chat, protocol audit and vial scanner on Premium (Oct 2026) |
| Community | None | Yes — "Trusted Circles" (App Store, Oct 2026) |
| Cited sources on site | Yes; PubMed/label-linked compound pages | Not assessed (Oct 2026) |
If breadth is what you want, PeptIQ has it. It runs on iOS, Android and the web, so it is not tied to one device; its library pairs tracking with dosing, half-life, stacking and status information for many compounds; and it adds protocol templates, AI features such as a companion chat and a vial scanner, optional cloud sync across devices, and a "Trusted Circles" community for accountability (Oct 2026). For someone who wants one app that both informs and records — and who wants that record on Android or in a browser — PeptIQ covers ground Pepti deliberately does not.
Said plainly: if you want an app that offers dosing and stacking guidance, or you are not on an iPhone, PeptIQ is the better fit and Pepti is the wrong tool for you.
Pepti's advantage is restraint. It publishes no dosing content at all, by design: it converts a figure you already have into a draw volume and U-100 syringe units and never suggests what the figure should be. It keeps everything on the device with no account and no cloud sync — not local-by-default-with-an-optional-cloud, but no cloud at all, the one exception being the optional AI coach conversation. Its reconstitution math and 12-site rotation are built in, and its compound reference pages cite their sources rather than asserting. For someone who specifically does not want a dosing library on their phone, that narrowness is the point.
On the mechanics, the two overlap more than the framing suggests. Both do reconstitution and draw-volume math, both track injection sites, and — contrary to a common assumption — both work without an account and store data on the device by default. PeptIQ then layers an optional account and cloud sync on top for those who want cross-device use; Pepti offers neither. If account-less, on-device tracking with a reconstitution calculator were your only criteria, either would do; the real fork is dosing content and platform.
Ask two questions. First: do you want the app to tell you about doses, protocols and stacks? If yes, PeptIQ is built for that; if you specifically want a tool that never does, Pepti is. Second: what are you carrying it on? PeptIQ runs on iOS, Android and web; Pepti is iPhone only. Those two answers decide it far more cleanly than any feature count.

No, not for basic use. PeptIQ's FAQ states it does not require account creation for basic functionality and that data is stored locally on the device by default, with cloud sync offered as an optional Premium feature (Oct 2026). Pepti goes further: it has no account and no cloud sync at all, and your data stays on the device apart from optional AI coach conversations.
Yes. PeptIQ lists iOS, Android and a web app at app.peptiq.io (Oct 2026). Pepti is iOS only and requires iOS 17.2 or later, so if you are on Android, PeptIQ is the one here that fits.
They differ here by design. PeptIQ's features page describes a peptide library with dosing and stacking information and dosing-schedule and protocol templates (Oct 2026). Pepti publishes no dosing content anywhere: you enter a figure you already have and it does the arithmetic, and it never suggests what that figure should be.
Both include reconstitution math. PeptIQ's site lists a reconstitution calculator including multi-peptide blends (Oct 2026); Pepti turns vial strength, diluent and a figure you already have into a draw volume and U-100 syringe units. The deciding question is editorial, not arithmetic: PeptIQ pairs the math with dosing content, Pepti deliberately supplies none.
Pepti is one flat tier: $16.99 per month or $69.99 per year in USD, with a 14-day free trial on the annual plan, no free tier. PeptIQ is free to download, with in-app purchases listed from $9.99 to $129.99 on its App Store listing (Oct 2026). Check its listing for the current figures.
Not medical advice. Pepti is a record-keeping and measurement tool, not a medical device. PeptIQ details are from its own public pages, October 2026; products change, so verify current details on PeptIQ's own pages.
