Planned in five languages." canonical: https://klmlabs.app/budget-planner/ updated: 2026-11-07 --- # Saldo: a budget planner that shows what's left until payday Saldo (working name) is a monthly budget planner in design for iPhone and iPad. Log a purchase in seconds, and see, while you're still at the till, how much of your money is left until payday. No account and no ads. **Status:** In design. Nothing is built yet; the pictures below are design previews. The name, like everything else on this page, may change before launch. [Email me when it launches](mailto:support@klmlabs.app?subject=Notify%20me%3A%20Saldo). No form and no mailing list: your email stays in our inbox, and we reply once, when the app is on the App Store. ## Pictures of the app - Design preview of the main screen: what's left this month and the per-day figure (Design preview — may change before launch) - Design preview of logging a purchase: the amount and the category buttons (Design preview — may change before launch) - Design preview of the budgets screen, each category marked under, near or over (Design preview — may change before launch) - Design preview of Insights: spending by week and by month, and the trend (Design preview — may change before launch) ## The problem it solves - You want to know, while you're still in the shop, what's left to spend until payday, without doing sums. - You want to log a purchase in seconds, without typing a description for every coffee. - You want a budget for each kind of spending, and to see early when one is about to run over. - You want rent and bills counted every month, without entering them again. ## Why we're making it If you're paid once a month, the number that matters is what's left until the next payday, and you need it at the till, not at home. Saldo is planned around that one number: log what you spend in a couple of taps, and the app keeps the rest of the month in view. ## Planned features What the first version is planned to do. Nothing is built yet, and the plan may change. - Log a purchase in seconds: the amount, then a tap on a category. - What's left this month, counted from the day your month starts, with a per-day figure. - A budget for each category that shows when you're under it, near it or over it. - Rent and bills that repeat every month on their own. - Insights by week and by month, and a trend that uses each month's own budget. - Sync through your own iCloud, and an export to CSV for a spreadsheet. ## Who it’s for People paid once a month who keep track of their spending by hand and want to stay on top of it day by day. - Someone paid on the 25th sets the month to start that day and checks the per-day figure before buying lunch. - A student logs a coffee with two taps at the counter and sees the eating-out budget turn to “near”. - A renter enters rent and the phone bill once, and every month starts with them already counted. - After a month of use, someone opens Insights to see which category ran over, then exports the month to a spreadsheet. ## Languages and devices Planned in English, German, French, Spanish and Italian, with your own currency and number formats. For iPhone and iPad. ## Price The price isn't set yet. It will show on the App Store page, and in the app before you pay. ## Who makes it, and your data KLM Labs, a small app studio run by its founder, Mayank Kumar Grover, makes this app. [About KLM Labs and how we check our pages](https://klmlabs.app/about/) ### Your data - No account to make. - Your entries stay on your devices; sync goes through your own iCloud. - No ads in the app. ### Hear when it launches [Email support@klmlabs.app to be told at launch](mailto:support@klmlabs.app?subject=Notify%20me%3A%20Saldo).
