Next Up Pro vs Magnetic Sensor

Customize Your Intervals, Your Way A fully customizable interval timer: Create your intervals. Specify reps, sets, colours and sounds. Tailor it to your purpose and needs. Minimal design and easy to use. Options for rep-based intervals and images. Display options: Choose to run your timer in a detailed view that auto-scrolls through intervals or a full-screen mode for a larger, easily visible display. Both modes support portrait and landscape orientations. Visual details: In detailed view, running intervals and sets are highlighted, providing a clear visual cue. For intervals with multiple reps, the highlighted area indicates the percentage completed. Set optional background colours on intervals for a visual cue. Light and dark mode versions are available and will adapt to your preferences set on your device. Quick actions: Set an interim intervals that will automatically be added between intervals. Optionally, end your timer with the interim interval. Skip or backtrack through intervals using intuitive arrow buttons. Swipe actions allow for easy deletion and duplication of intervals and sets. Automatically sync timers across all your devices! Share your timers with others! --- Interval Timer Pro features: • Unlimited Timers: Create as many timers as you like, with unlimited intervals. • Time-based and Rep-based Intervals: Create intervals based on time or reps, offering maximum flexibility. • Description, Length, and Reps: Set the details of each interval, customizing it to your precise requirements. • Interim Intervals: Quickly set up timers by adding interim intervals that run between each interval. • Interval Sets: Group intervals into sets and specify the desired number of set reps. • Interval Customization: Differentiate intervals with background colors, images/photos, and sounds. • Time Display: View countdown of each interval and total remaining time, with an option to display total elapsed time. • Sound Options: Enable countdown beeps, set interval/timer sounds, and/or enable text to speech. • Progress and Highlighting: View progress with highlighted current intervals and reps completed. • Start from Any Interval: Choose which interval to start the timer from, providing maximum control. • User-friendly Actions: Effortlessly manage intervals with swipe actions for deletion and duplication.

Magnetic Sensor turns your phone's built-in magnetometer into three precise tools: • Compass — A live, tilt-compensated compass with cardinal direction (N/E/S/W) and adjustable magnetic declination so the needle points to true north, not just magnetic north. • Metal Detector — Set a baseline reading anywhere, choose Low/Med/High sensitivity, and feel haptic pulses that get stronger as the field deviates. Perfect for finding studs in a wall, screws under drywall, or rebar in concrete. • Field Logger — Record samples at up to 60 Hz, then export to CSV via the share sheet. Saved recordings stay in the app for replay or re-export. KEY FEATURES • Live X / Y / Z axis readings + total field magnitude • Tilt-compensated heading using the accelerometer • Magnitude history sparkline + multi-channel chart • Rolling statistics: mean, standard deviation, RMS, range • Figure-8 calibration helper with quality indicator • Min / Max tracking with one-tap reset • Three sample rates: Slow (500 ms), Normal (100 ms), Fast (16 ms) • Light / Dark / System theme • English and Korean • Unit options: μT, mGauss, nT • Adjustable smoothing • Magnetic declination presets • Haptic alerts for the detector • Keep-screen-awake while recording • CSV export with full timestamp + per-axis data PRIVACY All sensor data is processed on-device and never leaves your phone. The app does not collect location, contacts, or personal information. Anonymous mobile advertising is used to keep the app free; you can watch a rewarded ad to unlock unlimited CSV sharing for the session. WHO IT'S FOR • Hobbyists exploring magnetic fields • DIYers detecting screws, studs, and rebar • Students collecting data for physics or geology projects • Hikers wanting a reliable phone compass • Anyone curious about the invisible field around them REQUIREMENTS A device with a magnetometer (most phones built since ~2013). The app cannot work on devices without one — it will tell you on launch.
