Swayni

Read full description

Swayni is a voice workout timer designed for people who bring their own routines. You bring the routine. Swayni talks you through it. Stop glancing at a stopwatch on your screen: set your phone down, put your earbuds in, and let clear audio cues guide you through every exercise, rest period, and set. STRUCTURE YOUR ROUTINE: WORKOUT → GROUPS → EXERCISES • Group Management: Organize your workout into custom-named groups. Set rounds (sets), rest between exercises, and rest between groups. • Versatile Movements: Supports both timed holds (countdown timer) and repetition exercises (tempo/rhythm counting), with alternating left and right sides. • Independent Exercise Library: 86 built-in exercises with illustrated posture demonstrations. Create custom exercises with photos and notes, or link a warm-up routine directly into your plan. VOICE COACHING: HANDS-FREE TRAINING • Up-next announcements, countdown alerts, and pre-rest reminders so you know what exercise comes next before rest ends. • Keeps running seamlessly in the background, on the Lock Screen, or while using other apps. • Fully offline voice synthesis: train anywhere without needing an internet connection. APPLE WATCH COMPANION • Starts automatically when you begin on iPhone. Raise your wrist to see the current exercise, countdown, real-time heart rate, and active calories. • Pause, resume, or skip exercises directly from your wrist, even when your iPhone is locked. • Seamlessly writes workouts to Apple Health and closes your daily Activity rings. TARGET MUSCLES & TRAINING CONSISTENCY • Muscle Distribution Map: Review recently targeted muscle groups with switchable male and female anatomical figures. • Exercise History: Track completed sessions for each individual movement. • Weekly Schedule & Heatmap: Organize which routines to train on each day of the week, with an activity heatmap to stay consistent. SYSTEM DETAILS & HARDWARE ADAPTATION • Live Activities and Dynamic Island support for real-time tracking at a glance. • Hands-free control with Siri and Shortcuts. • Tailored for iPhone Duo: half-fold it on a table with the timer up top and controls below. SWAYNI PRO Swayni is free to start. Pro unlocks unlimited workouts and custom exercises, longer-range muscle and history analysis, private multi-device iCloud sync, custom accent colors, custom app icons, and removes app recommendations. Your personal workout history remains fully accessible even if Pro expires. Pro also includes the Apple Watch companion and linked workout references. Pro is available as a monthly or yearly auto-renewing subscription (yearly plan includes a 7-day free trial), or as a one-time lifetime purchase covering offline features. Payment is charged to your Apple Account at confirmation. Manage or cancel anytime in your App Store Account Settings. DATA & PRIVACY • No Account Required: Your routines, custom movements, photos, and notes remain stored on your local device, syncing only through your private iCloud when Pro is active. • Strict Data Boundaries: Heart rate and workout calories are stored in Apple Health and displayed locally; Swayni never uploads health metrics. We collect only anonymous product usage and funnel telemetry (never including workout names, exercise details, photos, notes, or health metrics). • Swayni provides workout timing and audio guidance, not medical advice. Start at a comfortable pace and discontinue immediately if you experience pain, dizziness, or unusual discomfort. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

K Tempo

Features
Read full description

K Tempo is a restrained pelvic floor (Kegel) training tool: train to the rhythm you set, and check the effect with real metrics. Why it is different Ā· Fully customizable parameters — contract/relax seconds, reps, rest between sets. Follow evidence-based protocols instead of fixed levels Ā· Haptic and sound guidance — strong pulse to contract, light pulse to relax. Keep the rhythm without looking at the screen Ā· Runs in the background — leave the app or lock the screen and the session continues; the Dynamic Island and Lock Screen show the current phase Ā· Position dimension — lying, sitting, standing, moving. Track the path of progression that matters Ā· Training plans and progression suggestions — one template and one position per week; the rules are visible and nothing is changed automatically Ā· Self-defined metric tracking — define the metrics you actually care about and watch the real trend over 8–12 weeks, not streak counts Ā· Training heatmap and overlay charts — see at a glance whether you trained, and put training load and your metrics on the same chart Privacy No account, no server, no data collection. Everything stays on your device by default; optional iCloud sync keeps data only in your own private iCloud database. K Tempo is a training log. It is not a substitute for professional medical evaluation.
