more Every time I open the app I have to type my apple password. Dose mg is capped at 100mg, can’t add mcg. Can’t add a dose that’s 250mcg. Have to click and hold to add times(not sure if this is intentional) has good potential just has limitations.
Developer Response Sorry for the bad experience you had, both issues should have been resolved for a while. Sorry for the late reply I just saw your review now.

This app has simplified my tracking process. The inventory management and dose tracking give me a single app where I can track everything instead of the complicated spreadsheet I was using previously. I had a few suggestions for the developer and he reached out for more details and changes were made to the app very quickly. I cannot recommend this app enough.

I started using the app to track peptides. If you are tired of tracking everything manually in a note book then this app is for you. Track purchases, dilutions and even custom mixes.

This app is SO good. Well worth the investment to keep track of literally EVERYTHING. The only issue is that iOS 26 has broken it, it will not open, only crashes.
Developer Response I hope the issue is fixed now with the latest version. I am really sorry for the inconvenience this caused you.

2.20 Mar 16
Features
• Performance Improvements: Improved performance across the app including faster startup, smoother dashboard, and reduced hangs. More improvements to come.
• Redesigned Plotter: Completely redesigned the Plotter tool with schedule and experiment workspaces. Find it in Tools → Plotter.
• Plan to Protocol Conversion: Convert any plan into a protocol for better titration and tapering management.
• Improved Log Multiple: Refreshed the batch logging interface in Calendar with a cleaner design and smoother workflow.

2.18 Jan 20
Features:
• Hide Progress Pictures: Temporarily hide progress pictures across the app when sharing your screen. Choose a duration (1h, 2h, 12h, 24h, 7d, or Forever) or turn it off. Find it in Settings → Privacy.

• Advanced Concentration Curve Models: Choose how peptide concentrations are modeled. Long-Acting (default) works great for weekly injectables like Semaglutide and Tirzepatide. Fast-Acting captures rapid spikes for short half-life peptides like BPC-157 or TB-500. Sustained Release models depot formulations. Find it in Inventory → Peptides → any peptide (not a blend) → tap ? in the top right for visual examples.
• Create Blends from Vials: Mix individual peptide vials into custom blends when filling cartridges. Select 'Blend from Components' mode, choose vials from different peptides, and the app creates a new blend definition or matches an existing one.

• Chart Legend Highlight Mode: Tap any peptide in the concentration chart legend to isolate it; all other lines fade out and the Y-axis auto-scales to that peptide's range. Tap again to show all. On by default. Toggle in Dashboard > Chart Display Settings > Legend Highlight Mode.
• Improved History List: Visually improved history list view with cleaner cards, better spacing, and a date jump picker.
• Flexible Extended Cycles: Define on/off periods in days or weeks independently. Perfect for protocols like '50 days on, 2 weeks off'. Mix units freely for active and rest phases.

2.14 12/19/2025
Features
• Shared Plans - Assign a single dosing plan to multiple profiles. Perfect for couples or family members on the same plan—each person gets their own independent injection tracking. Toggle between Personal and Shared mode when creating or editing a plan (visible when you have 2+ profiles).
• Improved Procurement - Procurement now supports multiple tracking numbers per order, partial shipment receipts, and per-item status tracking. Receive items as they arrive, link them to tracking entries, and create inventory individually or in batches. The list view shows delivery status at a glance.
• Profile Tags on Widgets - Widgets now display your profile initial as a colored tag, making it easy to identify which profile's doses you're viewing at a glance.
• Smart Site Recommendations - Dashboard and Calendar now suggest optimal injection sites for today's doses, color-coded by rotation status. Tapping 'Log Now' pre-fills the suggested site. Enable per site in Settings → Injection Sites.
Bugs
• Fixed Concentration Chart for Custom Peptides - Concentration calculation settings now persist correctly for custom peptides and blends. Previously, disabling 'Disable Concentration Calculations' would revert after restarting the app.

2.13 12/14/2025
Features
• Profiles - Track Multiple People
Create separate profiles for different people managing the same inventory on the same device. Each profile has its own isolated injection history, dosing plans, weight entries, progress pictures, and injection sites—while sharing the same global inventory. Perfect for couples and families. Find it in Settings → Profiles.
• Override Expired Items
Expired cartridges and vials can now be manually extended in inventory. An "Extend Expiration Date" button appears for expired items, allowing you to extend the date by 28 days with a safety confirmation.
Bugs
• Fixed Plan Start Date Picker - The date picker when creating and editing plans works again.
• Fixed Cartridge Expiration Dates - Expiration dates are no longer forced when filling cartridges. You can now choose whether to set an expiration date or leave it blank.
Note: The Profiles feature is currently in beta. If you encounter any bugs, please email j.grundherr@pm.me with details.
2.12 11/29/2025
Features
• Inventory Shortage Alerts
The dashboard now warns you when your peptide supply might run out before your next order arrives. Tap the warning to see which compounds need attention and when to reorder based on your active plans and lead times.
• Split Daily Doses
Plans can now assign different doses to morning vs evening injections. Perfect for protocols that need unequal splits throughout the day. Lock one time slot and the remainder automatically flows to the other slots.
• Show Both Units and mL
New toggle in Settings displays both U-100 units and mL when logging doses. On by default to help verify measurements and reduce dosing errors.
Bugs
