Alethea vs Peptra: On-Device Logger vs Outcomes OS

*Updated October 5, 2026*

Short answer: Pick Peptra if you want a native on-device dose/protocol logger with a clear free tier and no cloud account. Pick Alethea if the job is “is this working?” across schedules, labs, multi-brand wearables, and AI on web/PWA.

Competitor facts are summarized from the public Peptra: Peptide Dose Tracker App Store listing as of October 2026 and may change — verify in the store before you buy. A separately branded PepTra Android listing exists from a different developer — it is not the same app.

Side-by-side

Peptra — on-device protocol logging

Peptra emphasizes cycles (weeks-on/off or stepped ramps), backdatable dose logs, vial inventory with run-out alerts, concentration converter, offline reminders, site map, and estimated level curves for compounds with published half-lives (Premium). Free forever covers unlimited dose logging with one active protocol.

Alethea — outcomes correlation on web/PWA

Alethea is built so doses sit next to sleep, HRV, weight, and labs, then AI answers from that combined history. Schedules and adherence (including skips and unlogged doses), recon math, and vial inventory are first-class.

Honest limits: web / PWA only. Free = no wearable sync. Not HIPAA-covered. No BAA. Not a pharmacy. Not Alethea Medical.

Pricing: Free $0; Premium $9.99/mo or $99.99/yr; Pro $29.99/mo or $299.99/yr; Clinic $1,990/yr (up to 10 patients, 3 staff; month-to-month $199/mo); Founding Member Pro $9.99/mo locked (first 50, web only). See pricing.

Pick Peptra if…

• On-device / no-account logging is non-negotiable
• A free one-protocol native logger is enough to start
• You do not need multi-brand wearable sync

Pick Alethea if…

• Multi-brand wearables + labs + adherence in one place is the job
• You want AI on *your* longitudinal stack
• You’re fine with web / installable PWA
