Roundup, vendor-neutral
There is no single best app - only the right fit for what you run. Below is a plain, vendor-neutral look at the main peptide and GLP-1 trackers, what each does well, and where it falls short. Pepteca takes no affiliate money from any of them, and we include our own upcoming tracker rather than pretend the field is empty.
Last updated August 2026
Platforms and prices change, and we checked these in August 2026. Each app's name links to its own page so you can confirm the current details before you commit. We take no commission if you choose any of them.
Free for one compound; Premium about $4.99/month or $39.99/year
Good at: The closest thing to a product-plus-content approach: native apps, a set of free no-login web calculators, and tracking that spans peptides, GLP-1s, and TRT, with pharmacokinetic curves and site rotation.
Watch for: Its written content is thin on linked sources compared with a citation-first reference, and the full multi-compound experience sits behind the subscription.
Freemium with a paid Pro tier
Good at: The most heavily marketed tracker in the niche, with dose logging, inventory and low-stock alerts, scheduling, progress photos, and encrypted backup.
Watch for: The authoritative App Store listing is iPhone-only, and the name is shared by more than one app, so confirm you are installing the right one. It grows mainly through paid ads rather than open, cited content.
Subscription, roughly $9.99 to $19.99/month, 14-day trial
Good at: Cross-platform, with a large compound reference library alongside the tracker and sync across devices.
Watch for: It runs a community supplier directory - pointing users toward where to buy. Pepteca does not do this and does not think a reference should; it is the exact model we avoid on trust grounds.
Freemium; paid premium tier (price not listed on the site)
Good at: A full free tier: injection logging, protocol scheduling, site rotation, vial inventory, calculators, and an education library, across all three platforms.
Watch for: The premium price is not shown up front, so you have to sign up to see where the paid line falls.
Free core; paid premium tier (price not listed on the site)
Good at: A clean, general injection tracker that works well for GLP-1 shots, weight charts, and side-effect logging, with a genuinely usable free tier.
Watch for: It is a general shot tracker rather than a peptide-specific tool, so there is no compound library and less peptide-aware inventory math.
Free reference and calculators now; tracker pricing to be set
Good at: Right now, the citation-first side: a cited compound library, free calculators, and unit and titration guides, with a clear line between what is studied and what is community-reported. The tracker we are building aims squarely at the gaps above - a vial inventory that actually deducts logged doses, multi-compound stacks tracked as one unit, reminders, and data you can export - with no vendor money and no supplier directory.
Watch for: The tracker is not out yet. Today Pepteca is a reference and toolkit; you can join the waitlist below to hear when the tracker opens.
We are building the tracker described above: dose logs, a vial inventory that deducts, stacks as one unit, reminders, and free data export - no vendor money. Join the waitlist and we will email you when it opens.
There is no single best - it depends on what you run and what you value. Regimen is the strongest all-rounder pairing native apps with free web tools; PeptIQ has a generous free tier across three platforms; Shotsy is a clean choice if you mainly track GLP-1 shots. mypeptidepal.ai is cross-platform but runs a supplier directory we would steer clear of. Pepteca is building its own tracker, and this roundup includes it honestly rather than pretending competitors do not exist.
Yes. Several apps have real free tiers - PeptIQ and Shotsy both let you log doses for free, and Regimen is free for a single compound. A spreadsheet is also free and, for a simple protocol, often enough. The paid tiers mostly unlock multi-compound stacks, richer inventory, and reminders.
Because a roundup that only recommends the site's own product is an advertisement, not a review. Pepteca takes no affiliate money from any app here and is not yet a tracker itself - the honest thing is to tell you what actually exists and where each option fits, including where a competitor is the better call for you.
