G-Force Meter+ Accelerometer shows the G-force your phone feels right now on every axis, then turns each drive, ride or run into a result you can read: press Start, press Stop, and a session card shows the peak G, the average G and how hard you cornered, accelerated and braked. ▶ Live G-force on every axis • Total G on a round gauge with a moving dot for the direction of the force • Lateral (X), longitudinal (Y) and vertical (Z) values side by side • Min, average, max and peak while you record, plus peak chips for lateral, accel and brake • A scrolling chart of X, Y, Z and total G, or a sentence that explains the current G level ▶ Stop and see the session Press Stop and a Session result card appears: • Duration, peak G and average G • Peak lateral, peak accel and peak brake • A second-by-second G trend line (the first 10 minutes of a session) • With the Car activity selected, a plain-language reading of the drive, from Gentle to Very hard, based on the peak horizontal G Every finished session is saved to History automatically (the last 20). A session shorter than 2 seconds is not saved. If you switch apps mid-session, recording pauses in the background and the same session resumes when you return, and a session cut off when the system closes the app is recovered into History on the next launch. Share a result as text in one tap. ▶ History and personal bests Open History from the top of the Meter screen: personal bests, every session with its G trend, your race runs and rolling runs. Export sessions, runs or rolling intervals as CSV. A statistics report CSV unlocks for 24 hours after a short ad. ▶ G-G friction circle A dedicated tab plots lateral against longitudinal G as a trail inside rings at 0.5, 1.0 and 1.5 G, with peak lateral, longitudinal and combined G, so you can see how much grip you used in corners and under braking. ▶ Race mode • 0-60 mph launch timing with raw and rollout times • 60-0 mph brake test with time, distance and speed shed, estimated from the motion sensors • Rolling intervals: 60-120 mph, 100-200 km/h, 30-50 mph or your own range • GPS cross-check with a GPS 0-60 time, a quarter mile time and trap speed. A good fix shows a GPS-verified badge, otherwise the result is labelled as a sensor estimate • Regen profile for electric cars: braking events sorted by their strength into likely regen (gentle) and likely friction (hard), with their maximum G ▶ Set up for your car • Dash or Holder mount, auto-level and Re-level now • Reference 1G (resting reads 1.00 G) or 0G (resting reads 0.00 G) • Display sensitivity from 0.5x to 2.0x for the live gauge; the result card always shows the true values • Activity presets for Car, Roller-coaster, Sport, Elevator and Aircraft explain what each G level means there • A Guide tab with 8 tips on mounting, reading each axis and typical G in daily life • The screen stays on while recording • Interface in 30 languages ▶ Good to know Readings come from the phone's motion sensor, so mount the phone firmly and level it before you record. Launch and braking times are estimates unless they carry the GPS-verified badge. Only drive-test where it is safe and legal. For drivers checking how smooth or hard they drive, track-day and drag-strip fans, roller-coaster riders, and students who want to see physics in numbers.

Mornel is a gentle planner for people who find planning itself the hard part. Say everything on your mind, out loud or in a chat, and Mornel turns it into a calm, structured plan you can actually follow. Designed with ADHD and neurodivergent brains in mind, and for anyone whose thoughts move faster than their to-do list. BRAIN DUMP → PLAN Tap or hold the mic and talk. Mornel transcribes your ramble, spreads it across the right days, and shows you a review sheet before anything lands on your plan. Nothing is added without your say-so. It never invents times you didn't mention; it just proposes them. It understands English and five other languages. PLAN BY CHATTING Ask Mornel is a planner you can talk to. It knows your schedule, your focus history, and your synced calendar events, and it proposes changes as tick-box suggestions. You approve each one, and anything applied can be undone for five minutes. The AI never edits your plan on its own. A CALM DAILY PLANNER • A gentle day timeline with time blocks, colours, and icons • Quick add with date, time, reminders, and subtasks • An inbox for thoughts that don't have a day yet • "Break into steps": AI splits a daunting task into small, doable sub-steps • Routines in their own band above the day, ticked off with a tap • Mood check-ins as often as you like, with the shape of your day in Insights • Yesterday check-in: tick off what you actually did and keep your streak honest FOCUS, BEAUTIFULLY Start a focus session from one minute to hours, single or multi-round. Sit inside hand-painted scenes that shift from day to golden hour to night, with ambient soundscapes (rain, café, brown noise and more). A lock-screen Live Activity keeps the countdown in view (iOS 16.1+; interactive buttons on iOS 17+). A PRIVATE JOURNAL Notebooks, a clean block editor, moods, and photos, protected by an optional Face ID lock. Export your words any time as PDF or plain Markdown; your writing is never trapped here. MEET YOUR PET A small companion that grows only from real work: focused minutes and genuinely completed tasks earn XP; tapping and buying never do. Levels never decay. Watch it evolve through title bands from Stray to Legend, keep it on a home-screen widget, and bring friends along. Share plan tags with people you invite, and cheer each other's streaks in a friends-only feed. FREE, HONESTLY The planner, focus timer, journaling and moods, streaks, cloud sync, and the Live Activity are free forever, with a fresh daily allowance of AI planning, chat, and journal assists. Mornel Pro removes the AI limits and adds Apple & Google Calendar sync, weekly repeats, custom reminder times, every soundscape, more journal photos, and full journal export, with monthly, yearly, and one-time lifetime options.
