This app is now legacy. It will be supported at least till Aug 2024.

Solutionist 2 is coming soon and it will be much better. And a lot more modern.

"Underneath the surface of Solutionist‘s simple UI is a complex and powerful system…" - 4/5 stars :

"You are only limited by your own imagination.. An incredibly powerful app." - 4 / 5 stars :

Solutionist is a simple, yet sophisticated app that allows you to save a formula or a sequence of formulae and create calculation templates. Once created, all you have to do is to enter inputs and get the outputs.


* Create custom multi-step calculation templates (Calcs).
* A calc can contain a sequence of formulae.
* Multiple inputs and outputs for each calc.
* Condition based formula usage: Assign different formulae for a field based on condition.
* Text message in output field: Because a number is not what you always want from a calculator. Eg) You need a BMI calculator to say if you are “healthy” or “overweight”.
* Share your creations via Airdrop, mail or any other file management app installed on your device.
* Folder structured arrangement of calcs for ease of access.
* Swipe right to copy, swipe left to paste.


Here are some example calcs created by Solutionist users for their own personal needs

* Discount calculator for shopping
* Taxi fare calculator for one’s own city
* Custom tax calculator
* Custom brokerage calculator for trading
* BMI calculator for health
* Impedance calculator for Sound Engineering
* Custom weight calculator at industries

"You are only limited by your own imagination.. An incredibly powerful app." :


* Intelligent typing assistance - keypad automatically grays out irrelevant buttons, guiding a valid formula entry.
* Intelligent warnings - to prompt in case of oversight mistakes.
* Thoughtfully designed and integrated feature set makes Solutionist a unique and powerful tool.


* Set a prefix or suffix for values. “25 inches” makes a lot more sense than just “25”
* Round/floor/ceil outputs up to 5 decimals. No one needs an endless list of decimal digits.


All the features and sophistication are hidden behind a simple, clean and intuitive interface.

Excellent and very helpful

I work in a plastic factory and we use formulas to figure roll weights and minutes per roll to name a few. This app has made it so easy to figure without remembering the formulas. There are some suggestions I have a small bug or two which I will be submitting to the developer. Other than that it's an excellent app!

Limited functionality

The application is really useful, but lack of decent editor and any math functions except power, makes it use really limited

Great app for engineers!

This is an excellent app that replaces any need for excel on the go. If you're thinking about downloading an excel app to do quick formulas, think about getting this first. Simple and easy to use.

Only thing that could be added is the ability to copy and paste formulas into the application if they are pre-templated with the format needed for this app.
