Where PeptIQ has the edge
Wearable integrations. PeptIQ connects directly to Whoop and Oura Ring, pulling recovery scores, strain, readiness, and HRV into the same view as injection logs. For users who already wear a Whoop or Oura, this is a genuine advantage. Regimen syncs with Apple Health and Google Health Connect but does not have direct Whoop or Oura integrations in 2026.
Bloodwork sync. PeptIQ integrates with Function Health, Quest, LabCorp, SuperHuman, and FHIR-compatible portals. If your workflow involves regular bloodwork and you want dose logs and labs in one view, PeptIQ handles this natively. Regimen currently requires manual entry for lab values.
Web app. PeptIQ runs in a browser at app.peptiq.io. For users who prefer desktop, this is an option Regimen does not offer. Regimen is iOS and Android only.
Where Regimen has the edge
Price. At $4.99/month, Regimen's premium tier costs one-quarter of PeptIQ's $19.99/month. Annually, that is $39.99 versus $99. For most users running 3 to 4 compounds, the tracking depth is comparable. The price difference is not.
Compound library depth. Regimen covers 600+ compounds including GLP-1 medications, TRT compounds, peptides, and research chemicals. PeptIQ covers 100+ peptides with strong educational content. For users tracking less common compounds (retatrutide, tesamorelin, MOTS-C, GHK-Cu, NAD+), Regimen's library is significantly broader.
App Store rating. Regimen holds a 4.9-star rating across 70+ reviews. PeptIQ holds a 4.2-star rating across 36 reviews. User satisfaction is measurably higher on Regimen.
Free tier. Regimen's free tier gives access to every feature (PK curves, health metric correlation, injection site tracking, reconstitution calculator) for one compound. PeptIQ's free tier is limited to basic tracking. Users who want to evaluate an app fully before committing can do so on Regimen at no cost.

Which app should you use?
Choose PeptIQ if you already use a Whoop or Oura Ring and want wearable data alongside your injection logs, or if you need direct bloodwork integration with Quest, LabCorp, or Function Health as part of a clinical or provider-guided workflow. The web app is also useful if you prefer managing protocols from a laptop.
Choose Regimen if you are tracking multiple compounds, especially GLP-1 medications, TRT, and peptides simultaneously, and want the broadest compound library at the lowest price. At $4.99/month versus $19.99/month, Regimen is the practical choice for most biohackers who do not require Whoop or bloodwork integration.
