Compare multiple calculations at once
When shopping online, calculate totals with shipping and points in parallel and see which store wins. Add a note for store or product names so you can review later at a glance.
CalcNote
A calculator made for trying things out.
CalcNote blends a calculator with notes, built for your phone. Run multiple calculations side by side, compare totals, tweak numbers, and recalculate as you think—just like on paper.
Main features & workflows
Track spending like notes
Jot down expenses with a category and you're done. No strict format—add dates or thoughts and it becomes your personal money log.
Plan trips with budget trial-and-error
Trip planning means trying options. Change transport costs, nights, or lodging and the total recalculates instantly. This is CalcNote's signature advantage in everyday planning.
From daily math to professional work
Currency conversion, unit conversion, math functions, and user-defined functions cover everything from daily calculations to advanced work.
Who it's for
- For people who compare real prices fast, including shipping and points.
- For those who tweak budgets (nights, transport, food) while watching the total.
- For anyone who logs spending as quick notes, not a rigid household ledger.
- For people who adjust formulas later and keep decisions moving.
- For anyone who wants one calculator for everyday life and work.

FAQ
How much does it cost?
Almost all features are free. A subscription plan removes ads and unlocks every feature.
Do you offer a one-time purchase version?
CalcNote originally shipped as two separate apps: the paid CalcNote Pro and the free CalcNote. Pro is still on Google Play to support existing users, and we plan to keep updating Pro as long as CalcNote continues to be developed. That means Pro effectively works like a lifetime license. That said, its price is set roughly at the cost of several years of the annual subscription, which helps fund ongoing development and support. For most new users, the subscription is usually the more practical choice.
Which platforms are supported?
CalcNote is available only on Android. There are no plans for an iOS release. If you're on iOS, we recommend Soulver—it's an excellent, well-crafted app.
Where can I get help?
We provide an online help guide and tutorial videos.
