Set your plan once. Every day, Stax shows what's due and you tap it done. That's the whole habit. Stax keeps your peptide routine on autopilot: doses, days, dose changes, phases and cycles, vials counting down, injection spots rotating, and a two-page report your doctor can read. Everything stays on your phone. No account, nothing to sign up for. PLAN IT ONCE - Enter your own plan: which peptide, which days, how much. - Every day, chosen weekdays, or every few days. - Dose changes on the day your plan says, week by week. - Phases that start when the last one ends; off-cycles when you need a break. - See the week ahead: tap any day to see what's planned. TAP IT DONE - Today's plan, nothing else. One tap per shot. - Took a different amount? Change it for that one shot without touching the plan. - Log an off-plan shot in two taps: amount, spot, done. Units, mg, mcg or IU. - Stax remembers the unit you usually log in and suggests names as you type. VIALS AND SUPPLIES - Add a vial and watch it count down as you log. - Know the day it runs out, before you're dry. - Syringes and alcohol pads can count down too. - Reconstitution worked out: vial, water, dose, to a mark on the syringe. INJECTION SPOTS - A body map remembers where the last one went. - Today, this week or this month at a glance. SEE YOUR PROGRESS - Every shot, day by day, per peptide. - Streaks, totals and charts; daily, weekly, monthly. - A quick daily check-in for energy, sleep and focus. PILLS AND VITAMINS, TOO - An organizer for the rest of your stack: morning, midday, evening, bed. - Scan a label to add a supplement. Nutrients add up as % of daily value, week by week. - Peptides stay front and center. A REPORT YOUR DOCTOR CAN READ - Two pages: shots day by day, doses and vials, injection spots, how you felt, supplements. - Made on your phone from what you logged. Share it only when you choose. WORKING WITH A CLINIC? - If your clinic uses Stax for clinics, they can send your plan to your phone and keep it up to date, and you can share your report back with a tap. REMINDERS THAT KEEP YOUR SECRET - One nudge on days your plan still has something left. - Playful and undercover: never names a peptide, never mentions injections or doses. PRIVATE BY DESIGN - No account, no sign-up, no ads, no tracking. - Your log, plan and settings are stored only on your device. - Deleting the app deletes everything. AND THERE IS STAX Stax is the purple dot who watches where you tap, gets excited while you type, and cheers when you log. Tracking should not feel like a chore. STAX PLUS Start with 14 days of everything, free. No card needed and nothing renews. After that, keep Stax Plus with a monthly or annual subscription or a one-time lifetime purchase, or keep using the free version (2 logs a day, reminders and progress). Stax Plus includes unlimited logging, your plan, supply and inventory tracking, and the doctor report. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation of purchase, and renewals are charged within 24 hours before the end of each period. Manage or cancel any time in Settings > Apple ID > Subscriptions. IMPORTANT Stax is a personal tracking tool, not medical advice. It does not recommend, diagnose or treat anything, and it does not suggest peptides, amounts or schedules. Everything in the app is entered by you. Talk to a qualified healthcare professional about your treatment. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://staxtrack.com/privacy-policy
