Acceleration vs Triad

'Acceleration' is special in two ways. First, it processes the readings from your built-in accelerometers in real time to show only horizontal acceleration. Second, it takes data directly from your built-in accelerometers, sidestepping built-in smoothing. Created originally to help EV drivers who were concerned that their brake lights were coming on inappropriately during regenerative braking, it can also be used to display braking and acceleration performance. It's a small app that's easy to use. You don't have to sign-in, there aren't any ads and an internet connection isn't needed. To use the app, set your device in one fixed place. Tap 'Calibrate' to let the app find the size and direction of gravity. Horizontal acceleration is now displayed. When 'Record' is tapped, for the next 13 seconds a scatter graph of calculated readings is displayed. Two green arrows let you increase or decrease the vertical scale of the graph. By default, unsmoothed data from your accelerometers is used. Tapping the 'Smooth' button continuously averages the last last ten readings. This helps to manage results. To help check the correct function of brake lights during regeneration, the 'Lamp' button displays a panel that changes from blue to yellow at 0.7m/s/s, and to red at 1.3m/s/s. Upgrading will let you save your sets of data to look at later. You can also export full-sized pictures of graphs into your camera roll. However, apart from this, the free version of this app is fully functional. This app takes raw data from the accelerometers - not the processed data provided by the operating system. When 'Calibrate' is pressed, the magnitude and direction of gravity is measured, relative to the device. The app then continues to collect data from the accelerometers, mathematically projecting it onto the plane perpendicular to the original gravity vector. It reports the magnitude of this projected vector. This process produces a reliable result for horizontal acceleration, whilst making you aware of jitter and sensitivity.

Most days pass without us really seeing them. Triad is a small daily habit that changes that. Three questions. Two minutes. One clear view of your life. Every evening, Triad asks you the same three questions, carefully chosen to show you what your day actually held: • What are you proud of today? • What are you grateful for today? • What did you learn or realize today? Three questions that do something bigger than they sound: they show you that your life, even on ordinary days, contains more than you usually notice. A JOURNAL THAT GROWS WITH YOU Every answer becomes part of your personal journal. Search it, filter it, revisit specific days. Mark the moments that mattered as standout highlights. Over weeks and months, a picture of who you are and how you're changing slowly takes shape. INSIGHTS THAT REVEAL PATTERNS Triad shows you the themes that have been shaping your days: what you keep coming back to, what's shifting, what matters. The mood overview makes positive and negative patterns visible and shows how your average mood develops across weeks and months. This helps you recognize changes, notable periods, and weekdays that typically stand out for you. WHY THREE QUESTIONS Not because three is a magic number. Because each question opens a different door: Pride builds self-worth. Gratitude shifts perspective. Learning moves you forward. Together, they cover the parts of a life worth paying attention to, without turning reflection into work. BACKED BY RESEARCH • People who write down three positive things daily are up to 25% happier and more optimistic (Emmons & McCullough, 2003; Seligman et al., 2005). • Gratitude exercises help break rumination cycles and reduce depressive thoughts (Lehr et al., 2021). • Just four weeks of daily reflection measurably increase resilience and lower stress (Lorenz et al., 2022). • Even one to two minutes a day can improve well-being in the long term (Seligman et al., 2005). FEATURES • Three structured reflection questions per day • Personal journal with search, filters, and monthly overview • Standout highlights for especially meaningful entries • Mood heatmap, weekly and monthly trends, and insights into recurring patterns • Quick notes for thoughts during the day • Custom themes including Dark Mode • Daily reminder at your preferred time • Privacy first: your entries stay yours START TODAY Two minutes tonight, and you'll close the day knowing what was actually in it. A week in, you'll start noticing things you would have missed. A month in, you'll have something most people never build: an honest record of your own life. Try Triad for free.
