Expense tracker
You'll know when your budget runs out before it happens.
Log every expense in one tap, in soles, dollars or euros. Volt Budget works out your pace and tells you whether you'll make it to the end of the month, how much you can spend per day and which category is getting out of hand.

How it works
Three steps and your budget looks after itself.
- 1
Set up your cycle
From the 1st of each month, from your payday, biweekly or weekly. Add your budget and your categories.
- 2
Log in one tap
Shortcuts like "Lunch S/ 15" or "Taxi" are saved with one tap. Offline too: it syncs on its own.
- 3
Watch your pace
"On track" or "at this pace your budget will run out on November 20". Adjust before you overspend.
Benefits
Everything you need to make it to the end of the month.
Clear projections
Projected close, the date your budget would run out and how much you can spend per day until the end.
Soles, dollars and euros
Use one or all three currencies, with a unified budget (BCRP exchange rate or your own) or one per currency.
Your cycle, your rules
Monthly, biweekly or weekly, starting on your payday. Change the rule whenever you want.
Everything editable
Create, edit, reorder and delete categories, payment methods (Yape, Plin, card…), shortcuts and fixed expenses.
Offline
Log in a taxi or at the market with no signal. When you are back online, everything syncs across your devices.
Alerts and reports
Alerts at 50, 80 and 100%, a daily reminder, reports per cycle and export to Excel or CSV.
Your pace
It warns you before you overspend, not after.
Volt Budget compares what you spend with what you'd have spent at an even pace. Fixed expenses (rent, utilities) don't inflate your daily pace: they're added separately, so the projection is realistic from day 1.
Heads up: at this pace your budget will run out in 9 days, on November 20 (10 days before the end).
To make it to the end, spend at most S/ 63.80 per day.
Budget by category
The white mark is what you'd have spent at an even pace (36.7%).

Currencies
Soles, dollars and euros. Together or apart.
Choose one, two or all three currencies. With a unified budget, each expense is converted with its day’s exchange rate (BCRP’s SBS rate, or your own) and keeps that value forever. If you prefer, keep one budget per currency.
One budget
Everything adds up in your main currency.
One per currency
Each currency with its own pace and projection.
Reports
Your numbers, clear and exportable.
Last cycles against your budget, spending by day of the week and by payment method, your biggest expenses and the category that changed the most. Export to Excel or CSV in one tap.

What people ask us most.
Is Volt Budget free?
Yes, and ad-free. Every feature is included.
Does it work offline?
Yes. Everything is saved on your phone first. When there is a connection, it syncs with your account and your other devices. You only need internet the first time you sign in.
How does the exchange rate work?
In unified mode we use the selling rate published by the BCRP (SBS rate for the dollar and the euro rate), or the value you set. Each expense keeps its day’s rate, so your totals don’t change when the dollar goes up or down.
Can I use my own cycle, for example from the 15th to the 14th?
Yes. The cycle can be monthly from any day, biweekly (for example, the 1st and 16th) or weekly. If you change it mid-month, the current cycle adjusts and the next ones follow the new rule.
Can I change the categories?
All of them. The default ones (Food, Transport, Home…) can be renamed, given another icon and color, reordered or deleted, and you can create your own. The same goes for payment methods and shortcuts.
What about fixed expenses like rent?
Add them once as a fixed expense (a day every month, every week or at the start of each cycle) and they log themselves. The ones still to come already count in the projection.
Can I use it on two phones?
Yes. Sign in with the same account. If you edit the same expense on both while offline, the latest edit wins when they sync.
How do I delete my account?
In the app: Settings → Account → Delete account. You can also do it from the “Delete account” page on this site.
