PepLedger – Peptide Tracker is a private iPhone app for people who already run a peptide, GLP-1, TRT, or longevity protocol and want the log on the phone, not in a sheet.

You log a dose. If that compound has a published half-life on file, What's Active Now shows an estimate of what is still left. Metabolism varies. It is not a blood test.

The library lists 456+ compounds as reference data. Browse is free. PepLedger does not sell peptides. A reconstitution calculator runs on the device. Inventory, site rotation, labs, and a discreet mode are included. iOS 18+, iPhone and iPad. No Android app.

Free dose and health log. 7-day Pro trial, then $6.99/mo or $49.99/yr. The paywall can be closed. Not a medical device. Not medical advice.

PepLedger features and specs

  • Specialized Tracking
    PepLedger appears to be designed for tracking peptide usage, dosages, and schedules, which can be valuable for users who need organized record-keeping for peptide-related regimens.
  • Web-Based Accessibility
    As a web application, it may be accessible from various devices without requiring installation, allowing users to log or check data from anywhere with internet access.
  • Niche Focus
    By focusing specifically on peptide logging rather than being a generic health app, it may offer more relevant fields, reminders, or features tailored to this specific use case.
  • Potential for Data Organization
    Users managing multiple peptides or complex protocols could benefit from centralized digital record-keeping instead of manual notes or spreadsheets.
  • Simplicity of Purpose
    A tool with a narrow, well-defined purpose can be easier to learn and use compared to broader, more complex health tracking platforms.

Possible disadvantages of PepLedger

  • Limited Public Information
    There is little publicly available detailed information about PepLedger's specific features, pricing, or user reviews, making it difficult to fully evaluate its quality and reliability.
  • Uncertain Regulatory Status
    Since peptides can be subject to legal and medical regulations depending on the region, an app centered on this topic may face questions about compliance, endorsement, or medical liability.
  • Possible Lack of Third-Party Validation
    Without established reviews, ratings, or a strong user base, it's hard to confirm the app's security, data privacy practices, or overall trustworthiness.
  • Narrow Use Case
    Because it is highly specialized for peptide tracking, it may not appeal to or be useful for a broader audience seeking general health or medication tracking tools.
  • Unknown Support and Updates
    There is no clear indication of how actively the app is maintained, whether customer support is responsive, or if new features are regularly added.

Analysis of Daystack

Overall verdict

  • I don't have verified, up-to-date information about Daystack (daystack.app) specifically, so I can't confirm its quality, features, or reputation with confidence. Based on the name and domain, it appears to be a productivity or task/day-planning tool, but I'd recommend checking recent user reviews, its official website, and app store ratings before forming a judgment.

Why this product is good

  • Unable to verify specific features or user feedback for this product from available information
  • Cannot confirm pricing, reliability, or company reputation without current data
  • No independent reviews or benchmarks are available in my knowledge base for this specific app

Recommended for

  • Users should independently research current reviews on sites like Product Hunt, Trustpilot, or Reddit
  • Best to try any free trial or demo version yourself to assess fit for personal or team productivity needs
  • Suitable to evaluate only after confirming it meets your specific requirements (e.g., task management, calendar integration, team collaboration)
