Stop relying on messy notes or complex spreadsheets – track everything accurately in one secure, easy-to-use app. Comprehensive Peptide Inventory Management: Log Any Peptide: Maintain a detailed database of all your compounds – from research peptides and GHRP/GHRH analogs (like CJC-1295 or Ipamorelin) to healing peptides and GLP-1s.

Perfect for managing complex peptide stacks or cycles.

About

Metre

Features
Read full description

Metre is a watch-first workout app for lifters who want to stay focused on the workout instead of reaching for their phone. Built for Apple Watch, Metre supports the rhythm of training: start a workout, begin a lift, track your sets, time your rest, and move into the next effort without breaking focus. Set up the workout before you start. Choose your sets and rest time for a lifting session, then let Metre carry you through the flow. You can also run Tabata, EMOM, and custom work-and-rest protocols from your wrist. Use Metre to: • Start workouts quickly from your wrist • Set the number of sets, rest time, and rounds before you begin • Move through programmed lifting, Tabata, EMOM, and interval workouts • Save workout records to Apple Health and view them later in Apple Fitness • Track lifts and total sets during a session • Time work and rest between sets • Add more rest when you need it • Use haptic feedback to know when it is time to lift again • Look back at your workout history before your next session Many workout apps are built around planning, logging, and extra features that pull attention away from the gym floor. Metre takes a simpler approach: do one thing, do it well. Your phone stays out of the way so you can lift, rest, and repeat with better rhythm from the start of the workout to the last set. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
