Stop logging dynamic repetitions for a static workout. Muscles respond to tension, and isometric bar training is the ultimate way to build raw, injury-resistant strength. But standard fitness trackers are built for dynamic gyms. They do not understand force-based holds, strap-slot heights, or the precise progressive overload rules required for true isometric gains. Enter ISOBEAST. ISOBEAST is a premium, high-contrast training log designed specifically for isometric bar (ISO-BAR) equipment. By tracking exact force, hold duration, and strap slot positions (1–36), ISOBEAST removes the guesswork and guides you through deterministic progression rules to ensure consistent, measurable strength increases. PRECISION ISOMETRIC LOGGING Log force, hold duration, and exact ISO-BAR hook slots (1–36) to record performance at specific muscle lengths. The speed-first UI lets you log a set in under three taps. DETERMINISTIC PROGRESSION ENGINE ISOBEAST automatically scores sets (Success, Neutral, Failure) and updates targets using transparent rules like double progression, time-target holds, and average-capacity tracking. BUILT-IN ISO-BAR / ISOCHAIN / ISOMAX PROGRAMS Load read-only training templates straight from the manual: • The Promethean (6-second holds with double progression) • 6x6 (fixed percentage of tested 1RM) • Military Power (max-effort singles with slot variation) • Iron Man (long holds for conditioning) • One-Rep Max Testing (averages peak force attempts) DEVELOPER-PREMIUM UX • Pre-filled target inputs based on previous session data. • Custom haptic logging alerts for clear tactile confirmations. • Automated rest timers with skip commands and background notifications. • Persistent Active Workout banner to resume or discard sessions safely. PR VAULT & TRENDS Track your all-time bests per slot/mode and watch your strength curve rise with interactive volume charts. SECURE SYNC & PRIVACY ISOBEAST securely stores your profile, routines, and workout logs in a private cloud database. All logins and tokens are encrypted and kept in the iOS secure keychain. We collect no tracking data and never sell your personal information. Unlock true tension-based strength. Track with ISOBEAST. Terms of Use: https://isobeast.app/terms/

About

DreamSweep

This app provides two distinct sleep scores: one for restorative sleep and another for brain waste clearance. It uses scientific research to offer personalized insights into sleep quality and its impact on cognitive health.

Highlights
  • Dual sleep scoring (Restorative Sleep Score, Brain Clearance Opportunity)
  • Age-fair scoring based on clinical norms
  • Transparent algorithm with explained weights
  • Integrates with Apple Watch and HealthKit
  • Compatible with Oura Ring and other wearables
  • Graceful degradation for missing sensor data

Your sleep does two things, and until now, no app told you about either of them. DreamSweep is the first sleep app that separately scores how well you recovered overnight and how well your sleep supported brain clearance. sleep. sweep. restore. WHY TWO SCORES? Sleep research has shown that sleep serves at least two distinct biological functions. Restoration is how your brain resets: synapses are pruned, memories are consolidated, and cognitive capacity is replenished. Brain waste clearance is a separate process: during deep sleep, the glymphatic system flushes out toxic proteins like amyloid-beta and tau, the molecules linked to Alzheimer disease. These two processes depend on different aspects of your sleep and can vary independently. A great night for recovery can be a poor night for brain clearance, and vice versa. Every other sleep app collapses this into one number. DreamSweep gives you both. YOUR TWO SCORES Restorative Sleep Score (RSS): Did your body and mind get what they needed? Modeled on sleep-lab methodology. Combines sleep duration, continuity, cycle architecture, and timing stability, scored against age-appropriate clinical norms. Brain Clearance Opportunity (BCO): Did your sleep support brain clearance? Based on the emerging science of the glymphatic system. Tracks deep sleep quality and heart-rate variability patterns linked to brain clearance activity. WHAT MAKES DREAMSWEEP DIFFERENT Two scores, two biological questions, not one opaque number. Every parameter traceable to a published scientific norm. Age-fair scoring: a well-slept 65-year-old earns a high score on age-appropriate criteria. Fully transparent algorithm, no black box, every weight explained. Grounded in peer-reviewed sleep science and glymphatic research. Graceful degradation: missing sensors drop out, your score always works. WHO IS DREAMSWEEP FOR Health-conscious adults who have outgrown single-number sleep scores. People investing in longevity and brain health. Users who want to understand their sleep, not just track it. Whether you are 30 and optimizing performance or 60 and protecting cognitive reserve, DreamSweep gives you the answers that matter. THE SCIENCE DreamSweep is grounded in decades of sleep research, including the seminal discovery of the glymphatic system by Iliff and Nedergaard (2012), landmark studies on sleep-driven brain clearance (Xie 2013, Fultz 2019), and AASM clinical scoring standards. Every scoring parameter traces back to a published source. REQUIREMENTS Works with Apple Watch (Series 4 or later) and Apple HealthKit. Also works with other HealthKit-connected wearables (some physiological features require Apple Watch). No special permissions or entitlements required. DreamSweep is a wellness product, not a medical device. Scores are wearable-derived estimates and are not intended to diagnose, treat, cure, or prevent any disease.
