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. 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. 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. 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. You can also export and import an encrypted .filo backup, 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.

Verdict
The clearest difference is price: Il Filo at Free against Sampling Calculator's $5.99. Il Filo also leads on update cadence (every 6 days vs every 16 months). Sampling Calculator's advantage is iOS requirement (15.6 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
