For when you know what to do and still can't start. Just start with 3 minutes, and the timer carries on from there. Calibrate is a calm pomodoro timer and to-do list, built for the moment before you begin. EMPTY YOUR HEAD FIRST Brain-dump every loose thing into one list for today. Big ones break into small steps. Spaces keep work, home and health apart, so today stays short. Every to-do gets a day, or waits without nagging you. START FROM YOUR LIST Swipe any to-do to just start: three minutes, then your block carries on by itself. REAL BLOCKS, REAL BREAKS Each block ends with one question: how was your focus? Then you choose: a break, or the next block. In the flow? Keep going, and answer when you stop. YOUR LOCK SCREEN DOES THE WORK The whole session lives on your Lock Screen and Apple Watch: the countdown, the check-ins, the next-block choice. Nothing needs unlocking. You never have to open the app. AN HONEST WEEK, NOT A SCORE The weekly recap shows how much you really did. Facts, never grades. No streaks, no scores. Miss a day, nothing breaks. WHO IT'S FOR Students in long study sessions. ADHD brains: the app never punishes a wandered mind, it just asks kindly. Anyone who's tried blockers and streak apps and wants something gentler. Calibrate helps you notice. It never notices for you. Focus sessions, to-dos, spaces and lists are free, all of it, unlimited. Calibrate Plus adds the long view: your weekly recap, your busiest hours, your habits month by month, and unlimited keeping track. Monthly, or one purchase that's yours for good.

Session Flow

Read full description

Session Flow is the calendar for anyone who works by appointment and wants to know, without mental math, who has paid and what's left to collect. It works for therapists and counselors, dietitians, physical therapists, private tutors, personal trainers, hair stylists, nail techs and anyone paid per visit. Add a client once, with the day, the time and the fee, and your schedule fills itself in. Every session shows its fee and whether it's been paid. Your schedule fills itself in • Weekly, every other week, monthly or your own repeat, with a set number of sessions if you need one. • Mark holidays and your time off, and the app cancels those sessions; change your mind and they come back. A client who travels gets a pause of their own. • No-shows, cancellations and rescheduling in one tap, with no math to redo. • Day, week and month views, with a warning when two times overlap. • Already use your phone's calendar? The app reads your appointments and sets up each client with you, one by one. Nothing in your calendar changes. Payments in one place • One tap on Mark as paid and the session is paid. • Per session or per month, a flat fee or the sum of the sessions: each client on their own terms. • A rate increase applies from its date on, and older open sessions keep the old rate. • Outstanding: the total and client by client, always up to date. • Prepayments become a balance, and each session draws from it (Premium). Reminders and payment messages on WhatsApp • The session reminder, with the day and time, is ready to send, and the day's list shows who still needs one. • The payment message is ready too, with the date of each open session and the total (Premium). You check it and send it. • Charge one by one: each client's payment message, one after the other (Premium). • Notifications on your phone before each session. Receipts and documents • Receipts, attendance letters and a superbill template, as PDFs with your details and your client's. • Ready-made templates, and your own. • A spreadsheet of payments received, for your accountant. Your month in numbers • Received, forecast and what's left, month by month. • Average ticket, % canceled and the month's chart (Essential and Premium). • On a tablet or computer, Insights: your year month by month and what needs attention this week (Premium). Your data stays with you • Works without an account and offline. Without the cloud, nothing leaves your phone. • No tracking. • Back up to a file whenever you want. • With the cloud (Premium), the same data on your phone, tablet and browser. • For health professionals: Session Flow is not a clinical record, and it keeps only what your schedule and payments need. Your work, your words • Call the people you see clients, patients or students, and each visit a session, appointment, consultation or class. • Groups, with each participant's fee and payments (Premium). • English, Portuguese and Spanish, with your currency and 12- or 24-hour time. Plans • Up to 4 clients, with no subscription and no time limit. • Essential: up to 40 clients and full statistics. • Premium: up to 1,000 clients, cloud sync, WhatsApp payment messages, groups, prepayments and Insights. • Essential and Premium come with a 14-day trial on your first subscription.
