APPLE WATCH CONTROLS Pause, resume, skip ahead and end the session from your Apple Watch. The phone stays the source of truth; the Watch confirms every tap with a haptic. TRAINING LOG TIMELINE Your training log is now a timeline of session cards (rounds, sparring, pads, HIIT, sprints and runs) with a one-tap Share on every card. SHARED WORKOUT PRESETS Send any timer profile as a link. It opens ready to start on a training partner's phone, or takes them to the App Store if they don't have RoundFlow yet. PAY ONCE The Lifetime Pass is a one-time purchase: pay once, no subscription needed, and every Pro feature is yours for good. Try Pro free first if you like. FIXED • Bug fixes and stability improvements. ### 1.6 — 2026-09-04 Pick your discipline. Start fast. DISCIPLINE PICKER Boxing, Muay Thai, MMA, Taekwondo or fitness — pick once and your first timer is ready before the paywall. Your first session is one tap away, and Home suggests the next one with a date. YOUR PUNCH COUNT IS FREE Every session logs your punch total with Apple Watch and writes to Apple Health — Pro or not. Pro reads it round by round, with heart rate, Effort and how fast you recovered. SHARES THAT INSTALL Every share card now carries a link and a QR code to the app. Present mode is a poster for the gym wall, with the room code when you train together. REMINDERS, ASKED ONCE After your first workout we ask if you want a reminder on your training days. Nothing else, and Settings keeps your plan either way. ALSO - The paywall opens on the free trial when one exists, and stays legible at large text sizes. - Rate RoundFlow from Settings. - Privacy manifest and a corrected privacy policy. ### 1.5 — 2026-09-02 The corner now calls combinations it can name. COMBO CALLS The coach voice calls real combinations - jab, cross, hook - from a library the corner can actually pronounce, not just numbers. PRESENT MODE Cast the timer to the gym wall: a clean, huge round clock a whole class can read. NEXT SESSION After your first workout, Home offers a concrete next date. Tap it to pick your days. Dismiss it and the plan stays one tap away in Settings. PAYWALL, HONESTLY It now says what stays free - the timer, the bell and your training log, forever. And at accessibility text sizes the price is finally on screen. FIXED - Eleven controls that looked live but did nothing now do what they say. - Plan cards no longer run off the screen at large text sizes. - The plan editor is reachable whether or not reminders are on. ### 1.4 — 2026-08-29 Know whether your hands were still there in the last round. OUTPUT PER ROUND The watch now slices your punches at every bell, so you see the shape of your session, not just a total. Elite output holds late — a falling profile is the same story your Gas Tank tells, read from the other side of the bell. CALIBRATE YOUR PUNCH DETECTION A short drill on the Apple Watch: throw ten jabs on the beat and RoundFlow learns what a punch feels like on your wrist. No more guessing at a sensitivity slider. HEART RATE AND PUNCHES ON THE LOCK SCREEN Your live BPM and punch count now ride along in the Live Activity and Dynamic Island. The phone on the gym floor is finally a real dashboard. COOL DOWN An optional two minutes of paced breathing after the final bell, with your heart-rate drop measured at the end. SIRI, SHORTCUTS AND WIDGETS "Start Muay Thai in RoundFlow." Start a specific timer or a roadwork run by voice or from the Action button, pin a timer to a home-screen widget, and put your streak on the Lock Screen. FIXED - The Lock Screen stays in step when you pause or skip a round. - Sessions interrupted while paused no longer write a full workout to Health. - Punch counts no longer carry over between back-to-back sessions. - Heart rate no longer sticks at its last value when the watch drops out. - The timer corrects itself after the system stalls it, instead of running long. - Group rounds stay in lockstep when several commands land at once. - Subscription status now updates reliably, including after a cancellation. - Better VoiceOver labels, Dynamic Type support, and a confirmation before a timer is deleted. ### 1.3 — 2026-08-12 Your music, handled properly. • The bell now survives switching to AirPods mid-round — before, the audio could go silent for the rest of the session. • Your music reliably resumes after a workout ends. • The coach finishes his sentence: "Breathe in" is no longer cut off by the rest announcement. The Corner breathes properly. • The breathing ring now moves through the whole inhale, holds at the top, and eases out — it used to freeze at full size for the first four seconds. Your training is recorded honestly. • Stop a workout early and it's logged with the rounds you actually did. Before, quitting after 8 of 12 rounds recorded nothing at all. • Sessions log the time you really trained, not the time you planned to. Plus: a circuit-training template, a clearer look across every screen, and the free plan now tells you where you stand before you hit the limit. ## Apps similar to RoundFlow | App | Rating | Price | Category | | --- | --- | --- | --- | | [AI Calorie Calculator Tracker](https://appshunter.io/ios/app/ai-calorie-calculator-tracker/id6746127427) | 4.3 (12) | Free | Health & Fitness | | [Halal AI: Scanner & Food Scan](https://appshunter.io/ios/app/halal-ai-scanner-and-food-scan/id6741214834) | 4.7 (265) | Free | Health & Fitness | | [AngelSense Guardian](https://appshunter.io/ios/app/angelsense-guardian/id1015546607) | 4.6 (387) | Free | Health & Fitness | | [Shadow Boxing Workout App](https://appshunter.io/ios/app/shadow-boxing-workout-app/id1510911574) | 4.9 (2,936) | Free | Health & Fitness | | [MarkRun: Walk to get rewards](https://appshunter.io/ios/app/markrun-walk-to-get-rewards/id6748003663) | 4.4 (4,031) | Free | Health & Fitness | ## More apps by Zakaria Elkassmi - [Vaktberegner](https://appshunter.io/ios/app/vaktberegner/id6785544934) - [Calque: Document Translator](https://appshunter.io/ios/app/calque-document-translator/id6800795744) All apps by Zakaria Elkassmi: https://appshunter.io/developer/6785544936 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
