Protocol vs Peptide Tracker & Calculator
#1 App Store result for peptide tracker
Which peptide tracking app is right for you?
Protocol is the more complete system. Peptide Tracker & Calculator is simpler and more established.
Peptide Tracker & Calculator is currently the #1 App Store result for 'peptide tracker' — a testament to their strong ASO and early mover advantage. They're solid for basic tracking and reconstitution math. But Protocol goes significantly further: three AI tools, supplement and habit tracking alongside peptides, bidirectional Apple Health, the Active Levels chart showing all compounds simultaneously, and a 73-profile research website. Protocol's free tier is also meaningfully more generous: 2 protocols with 5 items each.

Frequently asked questions
Why does Peptide Tracker & Calculator rank higher in the App Store?
App Store rankings are heavily influenced by review count, download velocity, and time in the market. Peptide Tracker & Calculator has been available longer and has more reviews. Protocol launched recently and is building its ranking — the ASO fundamentals (keywords, subtitle, description) are all optimized and rankings will improve as reviews accumulate.
Does Peptide Tracker & Calculator have an AI assistant?
No. It's a tracker and calculator without AI features. Protocol includes three AI tools: the Research Assistant for compound research, the Check-in Coach that analyzes your logged data after every check-in, and the AI Stack Builder that proposes full protocols from your goals.
Does Protocol have a better reconstitution calculator?
Protocol's reconstitution calculator is built into the inventory workflow — enter your vial size and target dose, choose Precise (10 units), Easy Draw (20 units), or Large Draw (50 units), and every future dose log references those exact numbers automatically. There's also a free web calculator at protocolapp.health/tools/reconstitution-calculator.
Which has a better free tier?
Protocol's free tier is more generous: 2 active protocols with up to 5 items each, plus 5 AI queries to start. This lets you build the full Injury Protocol example (TB-500 + BPC-157 + PT rehab + collagen) entirely on the free tier.
