Keep your vial records, schedules and notes together. PepMath is a personal peptide tracker built around Today, Journal and Vials. Record what happened, follow the schedule you entered and find your history when you need it. YOUR DAILY JOURNAL • Record taken or skipped entries, with your own amount and note. • Add past entries and correct amounts, dates and notes. • Search your journal and filter by vial, entry type, notes or date. • Browse the calendar and keep archived vial history in the same journal. • Undo recent entry deletions. YOUR VIALS AND SCHEDULES • Save a vial with just a name and add details when you are ready. • Choose your own weekdays or interval and a start date. • Enable local reminders after granting notification permission. Open PepMath regularly to refresh upcoming reminders. • Record stock on hand manually. Adding or editing journal entries does not change that stock. • Archive a vial to retain its history and free the active slot. FREE TO KEEP YOUR RECORDS One active vial, the full journal, archived history, basic reminders at the shared time and JSON export are free. Your saved records remain accessible and editable when a Pro subscription ends. PEPMATH PRO An optional monthly or yearly auto-renewable subscription adds unlimited active vials, individual reminder times and CSV export of vials and history. JSON export stays free. Pricing, billing periods and any eligible trial are shown before purchase. Subscriptions renew automatically unless canceled. Manage or cancel in your App Store account settings. LOCAL RECORDS No PepMath account is required. Vial and journal records are stored on your device. Export opens the iOS share sheet so you choose where to keep a copy. PepMath does not provide its own cloud sync or an export-import restore feature. PepMath records the values and schedules you enter. It does not calculate or recommend doses, dilution amounts or treatment plans, and does not provide medical advice.

Muffl

Muffl listens, but records nothing and sends nothing. When a sound you find hard appears — chewing, crunching, sniffing, keyboard tapping, a pen clicking — Muffl gently covers it with a soft layer of sound in your headphones. When it's quiet again, the layer fades away. The rest of the time you hear people as usual, so you can stay at the dinner table instead of leaving it. HOW IT WORKS • One big button. Turn the shield on from the app, Control Center, the Action button, Siri or your Apple Watch. • Pick the sounds that are hard for you: chewing, crunching, lip smacking, slurping, sniffing, heavy breathing, snoring, keyboard typing, pen clicking, tapping, a spoon on a cup. • Situation profiles: Dinner, Office, Transit, Cinema, Sleep next to snoring — each with its own triggers, masking sound and strength. • Eight masking sounds, generated live so they never loop or click: soft rain, rustling leaves, a brook, pink and brown noise, a low hum, café murmur, a warm fan. • Spectral fitting shapes the sound to the trigger's pitch, so it works at a lower volume. • Teach Muffl a sound of your own from a few examples. AFTERWARDS • A quiet diary of episodes and how they felt, with CSV and PDF export for your therapist. • A 30-second breathing circle when a moment was hard. PRIVATE • Audio is analysed in memory on your iPhone — nothing is written to storage and nothing leaves the device. No account, no ads, no analytics. • Optional iCloud sync for the diary uses your own private iCloud database. HONEST ABOUT LIMITS Muffl cannot remove sounds from the room and cannot switch your AirPods' modes. It adds a masking sound at the right moment. Best with AirPods Pro in Transparency mode; any headphones work. MUFFL PRO Free: the Dinner profile, up to 3 triggers, 45 minutes of shield a day and 3 days of diary. Muffl Pro removes the daily limit and unlocks every trigger and your own sounds, all profiles, all 8 masking sounds with spectral fitting, Apple Watch control and the full diary with export: yearly with a 7-day free trial, monthly, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in your Apple ID settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://evgeniybruchkovskiy.github.io/muffl-legal/privacy.html Muffl helps you get through trigger sounds. It is not a medical device, does not diagnose or treat any condition and does not replace working with a specialist.

Verdict
The clearest difference is iOS requirement: Muffl at 17.0 against PepMath's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
