Read full description

Protodose is a private personal routine tracker for adults who want a clear, reviewable record of the plan they enter themselves. Start by adding your own protocol details. Today then shows what is scheduled, with a clear choice to confirm, skip, or log an entry late. Every confirmed entry can be undone from Today. USER-INPUT CONCENTRATION CONVERSION Enter your own vial strength, liquid volume, dose, and syringe scale. Protodose shows the resulting volume and syringe units from those inputs. It does not recommend a concentration or dose. SUPPLY THAT MATCHES REAL LIFE Keep separate vial, pen, or other supply lots with preparation/open and expiry dates, batch/source notes, and remaining amount. Choose a supply when you confirm an entry; only then is its amount reduced. A PRIVATE ROUTINE RECORD - Daily, specific-day, every-X-day, and cycle schedules - Saved site history with a suggested next saved site - Calendar-ready dose history with confirm, skip, late, and undo actions - Optional self-reported weight, energy, sleep, and symptom observations - Local routine reminders scheduled ahead with a visible final scheduled date - User-initiated CSV and PDF exports plus a private local backup copy Your protocol, dose, notes, supply, and check-in details stay on your device. You choose whether to export or share a file. Protodose is for personal tracking and education only. It is not medical advice and is not a substitute for a qualified healthcare professional. IMPORTANT DISCLAIMER Protodose is intended for educational, informational, and record-keeping purposes only. The app does not provide medical advice, diagnosis, treatment recommendations, or dosing instructions. Always consult a qualified healthcare professional regarding medical decisions.

STAKK

Read full description

Take control of your peptide routine with STAKK. STAKK is an all-in-one peptide tracker, injection log, reconstitution calculator, and protocol organizer. Whether you are tracking GLP-1 medications such as Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Rybelsus®, Saxenda®, Victoza® or Trulicity®, peptides such as BPC-157 and TB-500, or a completely custom peptide stack, STAKK helps you keep your doses, injections, schedules, cycles, and history organized in one clean app. PEPTIDE & INJECTION TRACKING Record your injections in seconds and build a complete history of your routine. STAKK keeps your peptide, date, time, dose, and schedule together so you no longer have to rely on scattered notes, screenshots, spreadsheets, or memory. RECONSTITUTION CALCULATOR Take the repetitive math out of reconstitution. Enter the amount in your vial, the volume of reconstitution liquid, and the amount you want to measure. STAKK calculates the resulting concentration and corresponding syringe volume for you. CUSTOM PEPTIDE STACKS STAKK is built for more than one medication or peptide at a time. Organize multiple compounds into your personal stack while maintaining individual schedules, injection records, and histories for each one. SMART SCHEDULES & REMINDERS Create schedules around your routine and let STAKK help you keep track of what comes next. See upcoming injections, follow your cycle timeline, and receive reminders based on the schedules you create. Each peptide or medication can have its own independent schedule, giving you flexibility even when your routine contains multiple compounds with different intervals. INJECTION SITE ROTATION Keep track of where previous injections were administered using a visual injection-site history. Instead of trying to remember which location you used last time, STAKK gives you a simple record you can review whenever needed. CYCLE HISTORY & PROGRESS Your previous routines do not disappear once a cycle ends. STAKK keeps your logged history available so you can review past injections, timing, quantities, peptide combinations, and completed cycles over time. BUILT FOR PEPTIDE TRACKING STAKK can be used to organize many different peptide and GLP-1 routines, including semaglutide, tirzepatide, liraglutide, dulaglutide, retatrutide, BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, MOTS-c, Tesamorelin, Sermorelin, and custom entries. IMPORTANT HEALTH INFORMATION Availability, approval status, and permitted use of individual substances vary by country.

It does not provide medical advice, diagnosis, treatment recommendations, dosing recommendations, prescribing guidance, or instructions to begin, change, or discontinue any medication, peptide, or other substance.
