About

Willson

Features
Read full description

The Willson Software is a stress measurement tool. Stress levels are measured through the calculation of the user's RMSSD. The RMSSD value is obtained by detecting the user's heartbeat via the front camera. The subject places the phone flat on a smooth surface and then rests their index finger on the front camera. The measurement is valid precisely because the phone is still, as is the subject's hand. This procedure allows employees not only to understand their personal stress levels but also to identify critical work-related areas that generate stress, including the relationship between the user and their tasks, manager, and colleagues, as well as workplace motivation. Willson combines behavioral and psychophysiological measures to help workers identify and manage stressful situations in the workplace, using an interactive tree-like path and feedback mechanism. Additionally, Willson aims to assist companies and organizations by providing corporate wellness data and aiding in training needs analysis by aggregating individual user data. Specifically, the Willson Software operates through four phases of work: - Measurement of personal balance level in the absence of work-related stimuli (BASELINE). - Induction of work-related stimuli by compiling and computing the personal work 'to-do list' and measuring Heart Rate Variability (SETUP). - Activation of guided meditation to curb, limit, or eliminate stress in case of deviation from the baseline by 30% (TASK). - Measurement of stress after the TASK phase and optimization of the baseline (RECOVERY). The two main outputs are: - Stress value expressed as a percentage (relative to the baseline), both at an individual and aggregated level. - Collection of issues causing the most stress, both at an individual and aggregated level.

About

Il Filo

Il Filo keeps what happened, the decisions you made and what you want to do next, so you can resume without starting over. A project to move forward, a home to work on, a trip to plan or a family commitment to keep track of. Between one thing and another, days go by, plans change and decisions are made. When you return, you want to pick up where you left off. Il Filo fits any part of your life: anything you want to follow over time can become a Filo. EVERYTHING YOU NEED TO PICK UP AGAIN Create a Filo and gather the information that belongs to it. Add Traces to keep updates and decisions, choose the Step to take now and prepare the next ones. Write with bold text, highlights, lists and links. Add items to check off in Steps, record outcomes and keep audio notes up to two minutes long. The Timeline brings back your progress and Key Points, even weeks later. IMAGES AND DOCUMENTS, IN THEIR FILO Keep photos and PDFs in the Filo they belong to and link them to Steps and Traces. Swipe and zoom through full-screen images, read PDFs in the app and share files when needed. Find them in the Media and Documents sections. Attachments are in a free preview: up to 50 files in total across all Fili, with a maximum of 20 MB each. Later, new additions will require a subscription, even if unused slots remain. Existing attachments will remain accessible and manageable without a subscription. See Settings β†’ Attachments and limits for details. EXPENSES HAVE A CONTEXT TOO A quote for your home, a deposit for a trip, an expense to settle. With Budget, keep amounts and payments inside the Filo they belong to. Choose a currency, set an overall limit if you need one and add expenses. See what you have already paid and what you still expect to spend, compare estimates with your limit and link expenses to Steps. When you close a Budget, it stays in the Timeline. COMMITMENTS CONNECTED TO WHAT YOU ARE FOLLOWING Schedule Appointments within their Filo and find them in the Agenda alongside Steps with reminders. Filo cards show the nearest reminder across Steps and Appointments. Widgets show what to pick up again and today’s Appointments, right on your device’s Home Screen. A QUICK THOUGHT, READY FOR LATER Capture text and audio in Quick Notes, even before you know where they belong. Turn them into a Trace in an existing or new Filo whenever you’re ready. YOUR ORDER, YOUR POINTS OF REFERENCE Organize Fili into Collections with icons and colors, save favorites and customize your Home sections. Search, filter and sort archives by recent activity or name, with favorites first. Choose a soft header color for each Filo and switch between Content, Attachments and Budget with the dedicated selector. To get started, explore examples for home, travel, study, family and personal projects. YOUR CONTENT, UNDER YOUR CONTROL Il Filo is free and works offline, without a FILO account, ads or analytics tools. Keep your archive on your device or choose to sync it through your Apple Account’s private iCloud. If two changes need a decision, compare the versions and choose what to keep. Attachments and Filo colors also sync through iCloud. Export and import an encrypted .filo backup, including attachments, protected by a password or recovery key. Light and dark themes, adjustable text and an interface in Italian and English. When you return, the context is still there.
