A tuition tracking app that copies the month for you
In a spreadsheet, each client means 12 entries a year; in Diafixo, just one.
20 clients × 12 months = 240 spreadsheet entries. In Diafixo, 20: you add each one once. Sample math, using your number.
Made for people whose clients pay every month
- Your client's Pix lands straight in your account, with no platform fee on top.
- New phone? Sign in with the same email and your list is there.

Questions
Do I have to enter everyone every month?
No. You add each client once: name, WhatsApp number, amount and due day. On the 1st, that month's payment shows up by itself. Paused clients are skipped.
Does the app charge my clients automatically?
No. You tap Charge, WhatsApp opens with the message and the Pix code ready, and you send it. When the Pix lands, you tap Paid.
Is there a client limit?
Yes: 150 on Solo, 400 on Equipe and 1,000 on Empresa. At the limit, only adding a new client asks you to upgrade, and nothing you already have disappears.
Who is it for?
Anyone in Brazil who gets paid monthly by Pix. The app, the reminder messages and the billing are in Brazilian Portuguese and reais.
Add them once and let the month turn.
