Your workout notes, organized by date. Simpl is a flexible gym notebook for planning workouts, recording sessions, and remembering what matters. Instead of forcing every exercise, set, and rep into separate fields, Simpl lets you write naturally. Open a date, create a note, and start writing. KEY FEATURES • Keep multiple workout notes on any date • Write freely with simple Markdown formatting • Preview formatted notes without changing your original text • Save automatically as you write • Search by title, exercise, weight, text, or date • Sort results and quickly return to recent notes • Connect Apple Health to import completed workout summaries • Match Apple Watch workouts with existing notes or create new ones • Connect supported AI platforms and review workout proposals before saving them • Personalize AI proposals with your goals, equipment, schedule, and constraints • Choose between light and dark appearances • Sign in securely without a password YOU STAY IN CONTROL AI workout proposals never go directly into your calendar. Review, edit, reschedule, accept, or reject each proposal first. Apple Health integration is optional. Simpl reads only the completed workout information it needs and never writes to Apple Health. Routes, heart rate, and detailed biometric samples are not requested. Whether you are planning your next session, recording what you lifted, or looking back at previous training, Simpl keeps the process quick and uncomplicated. Writing should always be faster than configuring.
