Prime Factorization vs Panecal Scientific Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Prime Factorization
This utility app breaks down integers into their prime factors. It also calculates the number and sum of divisors, lists all divisors, and identifies specific number types like prime, perfect, abundant, or deficient.
- Prime factorization of integers
- Calculate number of divisors
- Sum of divisors calculation
- List all divisors
- Identify prime numbers
- Identify perfect, abundant, deficient numbers

[Description] Panecal is a scientific calculator app that lets you display and modify formulas. By allowing you to review your formulas as you type, it helps prevent typos and calculation errors. You can also reuse past formulas and utilize variable memory to recalculate by changing only specific values. The on-screen cursor allows you to quickly navigate to where you want to edit by tapping or using the arrow keys. Featuring a powerful, flexible, and intuitive user interface, the app also supports swiping to scroll through formulas and long-pressing to copy and paste. [Features] - Recalculate easily using past formulas - Effortless editing with cursor navigation and screen swiping - Copy and paste formula text - History log for both formulas and calculation results - Binary, octal, decimal, and hexadecimal calculation and conversion (Up to 32-bit) - M+/M- memory functions and variable memory (A–F) - Support for arithmetic operations, inverse trigonometric functions, logarithmic functions, power/root functions, factorials, absolute values, percentage calculations, modulo operations, and polar/cartesian coordinate conversion - Multiple angle units (DEG, RAD, GRAD) -Multiple display formats: Normal (standard), Fix (fixed decimal), Sci (significant figures), and Eng (engineering notation in multiples of 3) -Customizable decimal point characters and grouping separators [Disclaimer] Please note that Appsys accepts no responsibility for any damages, lost profits, or claims from third parties arising from the use of this software.

Verdict
The clearest difference is ads: Prime Factorization at none against Panecal Scientific Calculator's shown. Prime Factorization also leads on review sentiment (100% vs 76%) and monetization model (free vs ad-supported). Panecal Scientific Calculator's advantage is rating (4.8 vs 4.4) and ratings volume (2K vs 5). On price, update cadence, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Panecal Scientific Calculator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Panecal Scientific Calculator has 2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Prime Factorization's written reviews are positive against 76% of Panecal Scientific Calculator's, so the app with the better star average is not the one people write more warmly about.
Prime Factorization ships an update every 3 months, Panecal Scientific Calculator every 2 months. The most recent releases landed on October 15, 2026 and October 29, 2026 respectively.
