Peptides Calculator Rebuilds Its iOS App Around the Calculator

Peptides Calculator rolled out version 9.1.2 of its iOS app on Sept. 16, 2026, calling it the biggest redesign in the product’s history. The update puts the calculator back on the home screen, rebuilds six core screens, and adds lab appointment booking with email reminders.

Why it matters: - The redesign makes the app easier to use at a glance for the more than 50,000 researchers who found the product through the calculator. - The update shifts the app from a feature list to a day-by-day workflow for tracking vials, meals, labs, workouts and supplements. - The company is trying to keep the calculator as the entry point for users searching for a free peptide calculator app.

What happened: - Peptides Calculator released version 9.1.2 of its iOS app on Sept. 16, 2026. - The company says the release is the largest redesign in the app’s history. - The update rebuilds six core screens: vials list, vial detail, supplements, meals, workouts and the calendar. - The app now opens directly to the peptide calculator, which sits in the center tab. - The release adds in-app lab appointment booking with email reminders. - The update also adds set-by-set workout logging and multi-week meal-plan generation with live progress.

The details: - The redesigned calculator opens with a headerless, immediate flow that starts with the numbers. - A researcher can turn a calculator result into a tracked item in one step. - The calculator is the only place a tracked item is created, so plan figures stay consistent from day one. - A cycle-estimate section shows how much of a plan is needed across its full duration before anything is ordered. - The vials list now uses a colored supply rail on each card to show remaining inventory. - The supply rail stays in the app’s accent color while stock is healthy, turns amber when low and rose when it is time to reorder. - A quick-action row on the vials list lets users log, skip or undo today’s entry without opening the item. - The rebuilt vial detail screen keeps key figures, cycle status, stock on hand and full history visible on one screen. - Logging is now available from the item screen, the vials list or the calendar. - Logging opens a single sheet with the date and notes at the top. - Optional detail earns a small bonus in the app’s progression system, but the app still allows immediate logging without it. - Undo works from every screen, and history stays synced across the app. - The app supports fixed weekly days, alternating biweekly patterns and interval schedules. - Schedule notifications can go out as push alerts or calendar events. - The app rewards consistency with daily streaks, weekly challenges, achievements and an XP progression system. - The meal screen uses a Dayline timeline that shows what has been eaten, what is next and how the day tracks against calorie and macro targets. - Meal-plan generation now lets a user choose one to four weeks. - Each week builds with live progress, can be canceled mid-run and keeps completed weeks. - The app generates each week with variety constraints to avoid repeating earlier weeks. - The lab suite now includes in-app appointment booking and an email reminder option ahead of the appointment. - Standing lab reminders for recurring panels now live on the same unified screen. - The app already reads lab results by scan, tracks more than 40 markers across eight categories and charts marker trends across draws. - The app also generates AI comparison insights that flag which markers moved between panels. - The exercise screen is rebuilt as Set Track. - Set Track shows working weight with a load rail, set markers that fill as sets are completed and a week ribbon for training rhythm. - Workout logging happens set by set, including partial progress. - The supplements list now uses the same supply-rail design as vials and adds an adherence strip. - Finished supplements can now be archived instead of deleted. - A new My Journey screen becomes the progress home for streaks, adherence, weight trends and wellness scores. - The redesigned calendar presents the week as a clean timeline with day-off support. - The app includes a searchable peptide encyclopedia with more than 100 profiles. - Each profile includes category, typical half-life and general reference notes drawn from public descriptions. - The company also maintains free web tools at peptidescalculator.app for users who are not in the app. - Those tools include a peptide half-life reference chart. - The web figures mirror the app’s figures, and the tools run in any browser with no account required. - The core app remains free, including the calculator, vial and item tracking, logging, the peptide encyclopedia, supplements, the calendar, and the redesigned meal and workout surfaces. - A Pro subscription adds unlimited tracked items, advanced scheduling, lab scan tracking and AI-assisted features. - The app is fully localized in English and Spanish. - Existing data carries forward unchanged, including vials, supplements, logs, lab results, streaks and plans. - The Apple Watch companion still shows reminders, current streaks, water intake, weight history and HealthKit workout and heart-rate data.

Between the lines: - The redesign suggests Peptides Calculator wants to be read as a workflow tool, not a database of separate features. - Putting the calculator first also reinforces the app’s identity for users who arrive through search. - The lab booking and reminder tools close a loop between planning, tracking and follow-through. - The app’s free tier stays broad, while the subscription is reserved for heavier usage and AI-linked functions.

What's next: - The company is positioning 9.1.2 as the new default experience for iOS and Apple Watch users. - Researchers can compare the redesigned app directly because the calculator is now the first screen they will see. - Existing users can keep their data and continue on the updated workflow without re-entering records.

The bottom line: - Peptides Calculator’s biggest update so far centers the app on its namesake calculator and rebuilds the rest of the product around a simpler, timeline-style day view.
