PunchLab ā Punch & Kick Force Meter PunchLab turns your iPhone into a professional punch and kick force meter, giving boxers, martial artists and trainers instant feedback on strike power and technique. How it works Secure your iPhone to the punching bag using an armband, tape or stretch band. PunchLab uses the phone's built-in accelerometer to detect each impact and calculate the force in Newtons, along with the angle of the strike from the ideal hitting axis. Three training modes Power Mode ā measures and announces the force of each individual strike as you train Speed Mode ā counts how many strikes you land in a set time period Time Mode ā records how long it takes to reach a target number of strikes Solo and Two-Phone modes Use PunchLab on a single iPhone attached to the bag, or pair two iPhones via Bluetooth ā one on the bag as the Sender, one with the trainer as the Receiver ā for real-time coaching from ringside. Training feedback Force reading in Newtons for every strike Strike angle showing how straight and true each punch lands Hit count and session averages Visual gauge and bar chart updated in real time Optional spoken readout of force and angle after each strike Session logging Every session is logged with a full hit-by-hit table showing force, angle and timing. Logs can be emailed directly from the app for ongoing performance tracking. Unlock email reporting A one-time in-app purchase unlocks the ability to email session logs, perfect for trainers tracking multiple athletes over time.

Sleep tracking and a smart alarm, using the phone you already own. No watch. No band. Nothing extra to wear or charge. Every morning: a sleep score that shows its working, and one thing to do tonight. A SMART ALARM YOU CANNOT SLEEP THROUGH Set the latest time you want to be up. For the final 30 minutes Sleepfy watches for movement and, when you are already stirring, eases you awake with sound and gentle vibration rather than a jolt. Open the app and a sunrise is waiting. The alarm is scheduled through iOS. It rings on time, at full volume, even on Silent or in a Focus mode. The gentle part is a bonus. The time is guaranteed. A SCORE THAT EXPLAINS ITSELF Trackers hand you a number. Sleepfy shows the working: sleep against your goal, how late you turned in and how steady your schedule is, each with what it cost or earned. ADVICE FROM YOUR OWN NIGHTS Not the tips every app gives you. Sleepfy reads your history and ends every insight with one thing to do tonight, and when: in bed by 10:40 PM, last coffee before 2:10 PM. Home and Trends work from the same bedtime, wake time and sleep debt. YOUR JOURNAL, MEASURED Log caffeine, alcohol, exercise, stress, screens before bed and dinner. Sleepfy lines each one up with your measured sleep, so you see how your nights compare after it. NINETY NIGHTS ON ONE SCREEN Your last 90 nights, one square each, coloured by sleep against your goal. Tap any night for its date and duration. Your score and bedtime consistency show their change from the week before. HEAR WHAT WAS IN THE ROOM Snoring, talking, coughing, a door, a dog outside. Sleepfy picks them out, times them to the minute and gives them their own card on Home. Play them back: a snoring report you can listen to is one you can check. If an alarm or a call interrupts tracking, Sleepfy picks up again as soon as iOS allows, and the minutes it missed show as a gap, never as time awake. SEE THE SHAPE OF YOUR NIGHT Deep, light, REM and awake time, with a graph of the night. They are estimates, and Sleepfy says so. Deep sleep is judged against what is typical for your age. HOW IT WORKS Before bed, tap Start and put your phone face down on the mattress near your pillow, plugged in. Sleepfy listens to the room and reads its motion sensors overnight. Short clips from the latest night are kept so you can hear them; the next night replaces them, and you can switch this off. Tap Stop in the morning and your report is ready. YOUR DATA STAYS YOURS No account to create. Your sleep data stays on your iPhone and in your private iCloud, encrypted and tied to your Apple ID. We cannot read it. Nothing is sold, there are no ads, and you can clear everything in Settings at any time. EVERYTHING ELSE ⢠Five home screen widget styles ⢠Streaks for a steady schedule, with a goal you can change ⢠Change your sleep goal and manage your subscription in Settings ⢠Private iCloud sync: your history survives a new iPhone and a reinstall WORKS WITH APPLE HEALTH Sleepfy reads from and writes to Apple Health. With an Apple Watch, it uses the Watch's measured sleep stages instead of estimates. SLEEPFY PREMIUM Sleepfy is free to download.
