Diby
Read full descriptionHide full description
Diby is a coaching app for fitness coaches and the people they train. Coaches get a workspace to run the whole practice. Athletes get a clean place to train. Both live in the same app β switch between them from the workspace picker. FOR COACHES β’ Clients β your full roster in one list. Open anyone to see goals, body-metric history, check-ins, injuries and notes. β’ Calendar β 1:1 sessions, group classes, assessments and your own planning blocks. Invite clients individually or by group and see who accepted. β’ Library β build workouts from an exercise library, organize them into programs and phases, and reuse them across your roster. β’ Sessions β assign the work, then follow it set by set. Prescribed vs actual on every set, with RPE and per-set feedback. β’ Groups β bundle clients into training groups and schedule them together. β’ Messages β one thread per client, with unread counts so nothing slips. FOR ATHLETES β’ Your week at a glance: what's assigned, what's due, what you've finished. β’ A workout player built for the gym floor β big targets, quick logging, no hunting for the next set. β’ Track weight, body fat, measurements and progress notes over time. β’ Keep your own exercises and workouts alongside anything your coach assigns. WHY COACHES SWITCH Most coaching practices run on a spreadsheet, a notes app and a chat thread. Diby replaces all three without asking you to change how you coach β your programming, your language, your structure, in one place, on the device you already carry to the gym. Diby is available in English, Croatian, Portuguese (Brazil), Spanish and German. Questions or feedback: help@diby.io Terms of Use (EULA): https://diby.io/terms Privacy Policy: https://diby.io/privacy
