Inseries Pro: Smart Calculator4.0.1 - App Store
You'll be able to see results in few seconds.
Publisher Description
The smart, modern, and elegant calculator app - optimized for multi-touch
* Easy, logical entering of calculations and clear history of previous results
* Built-in calendar functions (e.g., number of days between two dates)
* Naturally adding and subtracting percentages (e.g., 99+20% taxes or 79-30% discount)
* Gesture support for fast access to previous results and memory
Inseries is the slightly different professional calculator app that allows you to naturally enter calculations and clearly browse your previous results. Simply type in "100+20%" to add taxes, or "100-30%" to easily calculate a discount. Inseries even shows you "pi" as a real constant instead of just a number.
Inseries' clear user interface is designed for multitouch allowing us to come by with a small and simple keypad based on the clear keypad layouts of typical financial and business calculators. By using choosers for quickly accessing functions and constants we could bring in scientific calculator functionality without sacrificing usability.

Version History Inseries 4.0.1 fixes some bugs and of course includes all the improvements of Inseries 4:
- Updated calculation engine with increased accuracy and reduced rounding errors
- Long numbers are now automatically displayed in scientific (“E”) notation for improved clarity
- The secondary function of the CLEAR button now provides CM (Clear Memory), as this is used more frequently than the previous ALL (Clear All) function 4.0.1 Jul 7 Inseries 4 includes several notable improvements:
- Updated calculation engine with increased accuracy and reduced rounding errors
- Long numbers are now automatically displayed in scientific (“E”) notation for improved clarity
- The secondary function of the CLEAR button now provides CM (Clear Memory), as this is used more frequently than the previous ALL (Clear All) function 4.0 Mar 3 Subtle improvements to better fit new iOS design. 3.7 10/13/2025 Beside general usability improvements and minor bug fixes, Inseries 3.6 comes with the following new features:
- New year-month-day ("YM") format for date calculations
- Extended result field context menu featuring memory operations
- Improved copy & paste functionality 3.6 07/21/2025 Performance improvements and bug fixes. 3.5.1 09/10/2022 Inseries 3.5 provides bug fixes and stability improvements. 3.5 03/01/2022 Inseries 3.4 includes some under-the-hood improvements. 3.4 11/19/2021 Inseries 3.3.1 provides a couple of usability improvements and bugs fixes. 3.3.1 03/14/2021 Inseries 3.3 makes our smart calculator app even better through a number of bug fixes and usability improvements.
Additionally, we changed the "Clear Memory" keyboard shortcut to SHIFT+CMD+s, since we strongly believe this new key combination is more logical and intuitive. 3.3 02/09/2021 Inseries 3.2 improves overall usability with focus on iPad. Specifically, we are introducing a number of practical keyboard shortcuts:
- Copy Result (SHIFT+CMD+C)
- Clear Result (CMD+BACKSPACE)
- Restore Result (SHIFT+CMD+BACKSPACE)
- Store in memory (CMD+S)
- Recall from memory (CMD+R)
- Clear Memory (CTRL+CMD+BACKSPACE)
- Toggle Fraction Digits (CMD+D)
- Toggle Date Format (SHIFT+CMD+D) 3.2 12/11/2020 Inseries 3.1 fixes a few bugs and of course comes with all the nice, practical new features of Inseries 3:
- New operators for factorial, (square) root and exponentiation
- Extended and also simplified date calculations
- Actual Greek symbols for constants such as π
- Improved, more consistent swipe gestures 3.1 05/06/2020 Welcome to Inseries 3! Inseries has been rewritten from the ground up using Swift and runs now natively on iPad for the first time!
Inseries 3 also comes with many great, practical new features:
- New operators for factorial, (square) root and exponentiation
- Extended and also simplified date calculations
- Actual Greek symbols for constants such as π
- Improved, more consistent swipe gestures
- And of course Dark Mode ;-)
Additionally, we also further optimized the keypad layout and improved overall calculation error handling -- we hope you like the new version as much as we do! :-) 3.0 10/14/2019 Inseries 2.1.1 provides optimized support for the screen resolution of the new iPhone XS Max. 2.1.1 09/25/2018 Inseries 2.1 provides faster access to functions and constants via new secondary keypads. In addition, the new version now also takes advantage of the iPhone X's full screen size and provides a few new functions such as en explicit "rad" conversion function, or a date function for calculating tomorrow's date ("tom"). 2.1 08/24/2018 Inseries 2.0 provides a number of significant improvements over previous versions of our smart calculator app:
- New, simplified keypad that makes various input tasks a lot easier through 2nd functions via long-pressing a key — especially entering hex numbers and accessing the most common constants (pi and e)
- More clear representation of past calculations through color coding and more natural operator characters for multiplications and divisions
- Faster way to perform date calculations: you can now easily add days to a date via the standard ‘+’ operator and calculate the number of days between two dates by subtracting them from each other
And finally (we know, long overdue): native support for iPhone 6 and iPhone 6+ screen sizes. Hope you enjoy the new update! 2.0 06/30/2015 Minor stability and usability improvements. 1.6 03/01/2014 Inseries 1.5 adds calendar functions for adding days to a date, calculating the number of days between two dates, or to determine the calendar week based on a given date.

The update also refreshes the look & feel slightly to be even more in line with the new overall design. In addition, there is a new "0" fraction digits mode that allows displaying results as rounded integer numbers. 1.4 09/17/2013 Inseries 1.3.1 fixes a database reloading problem related to many previous calculations as well as a few minor user interface issues. 1.3.1 07/26/2013 Inseries 1.3 introduces additional number formats such as hexadecimal, binary and degrees as well as functions to convert between these formats. Additional new features include:
* Degrees key for easily calculating directly with degrees; use the new DEC (short for decimal) function to convert degrees to radians
* Expandable keypad featuring A-F keys for entering hexadecimal numbers (swipe up/down in the upper rows of keys to expand/collapse the keypad)
* Easily enter hex and binary numbers using common "#ff20ea" and "%100101" notations
