Calculator of Formulas vs Intuitive Memory Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Calculator of Formulas
This application calculates and graphs mathematical formulas with multiple variables. It allows for programming complex equations, plotting graphs with variable manipulation, and saving frequently used formulas. It also generates tables of results for easy export.
- Programs formulas with up to six variables
- Plots graphs with variable manipulation
- Ray plotting for n-dimensional functions
- Graph tracing and intuitive touch gestures
- Saves formulas with descriptions
- Creates tables of calculated results
- Includes help files and tutorials

This app is focused on calculating and graphing mathematical formulas for everyday life and work. What distinguishes it from many other RPN calculators available at the App Store? Some of them allow for formula coding, do graphs, and are free, too. Unfortunately, most of these apps feature formulas of only one variable. In most real life applications, however, mathematical formulas have multiple variables! This app does all of the above plus the following: * Programs mathematical formulas with up to six variables. * Is simple to use. * Plots graphs with respect to a chosen single variable while keeping all other variables fixed. * Plots graphs when all the variables are changing along a user-prescribed vector. This relatively new concept of "ray plotting" enables user to probe a function in n dimensions by looking at its 1-dimensional slices. * Does graph tracing and enables graph manipulation with a simple set of intuitive touch gestures instead of button/pop up controls. * Saves most used formulas along with detailed description for later use. * Creates tables of calculated results that can be pasted into other applications. * Has an exhaustive set of help files and tutorials.
Intuitive Memory Calculator
This app simplifies complex calculations by offering multiple memory slots to store and retrieve numbers. It allows for unlimited access to stored values and keeps a history of your recent computations. Easily manage multiple numbers for multistep problem-solving.
- Multiple memory slots
- Unlimited number retrieval
- Recent calculation history
- Easy memory slot management
- Intuitive interface

Have you ever memorized or written down numbers while performing complex calculations? Intuitive Memory Calculator solves this problem with multiple memory slots that make it easy to store and retrieve numbers for multistep calculations! Simply tap a memory slot to store a number and tap it again to retrieve a stored number unlimited times. When you ready to clear a memory slot, swipe up on that slot and tap Delete. Additionally, you can now access 25 of your most recent calculations. Many traditional calculators with memory would have up to five buttons (MS, MR, MC, M+, or M-) just to allow you to keep track of one number! Intuitive Memory Calculator has three memory slots which allow you to keep track of three different numbers and each slot was designed to take up no more space than any other button in this calculator.

Verdict
The clearest difference is review sentiment: Intuitive Memory Calculator at 90% against Calculator of Formulas's 33%. Intuitive Memory Calculator also leads on update cadence (every 6 weeks vs every 17 months) and ratings volume (46 vs 1). Calculator of Formulas's advantage is rating (5.0 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Calculator of Formulas holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Intuitive Memory Calculator has 46 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Calculator of Formulas's written reviews are positive against 90% of Intuitive Memory Calculator's, so the app with the better star average is not the one people write more warmly about.
Calculator of Formulas ships an update every 17 months, Intuitive Memory Calculator every 6 weeks. The most recent releases landed on June 4, 2026 and August 15, 2026 respectively.
