## Prime Factors Reviews in United States

### ***** "The best for me"
Edit: this app quite working a few months ago after ios18 updates. Still shows primes but doesn’t show factors of other numbers when you click on them.  

Really loved this app before. 

This app is perfect for me, I’m always jotting numbers down for patterns and god knows what. Big problem tho. It quite working after ios18 update. Please fix asap.
-- Ryansgutters6, 2025-03-06

### *---- "No longer works"
App only identifies prime numbers in red but does not give the prime factors of the nonprime numbers.
-- WastedAllofMyMoney, 2025-02-09

### *---- "Dec 2024. App does not work"
When I try to press a number absolutely nothing works, and this is across all of my iPads. I think this app is completely broken. Do not download until the developer has updated it.
-- The Jones Journal, 2024-12-07

### *---- "Not working"
When I click on a number nothing happens. I can’t see properties. Fraud app. Spam
-- Wildgremlins, 2024-10-29

### ***** "Helpful"
Just yep it’s great.
-- Rockstar576787, 2020-03-12

### **--- "I would rather pay to see no ads"
The app works, but the ads are very, very annoying. It’s a combination of outside ads and ads for the developers own apps. I would rather pay for the app than see the ads. If I didn’t have to see the ads, I would rate this app four or five stars. I am deleting this app, I can’t handle the ads.
-- Rambo8649, 2019-01-10

### ***** "Greaaaaat"
This app is really good! I love how far up it can go. It can go up to over 100 Billion!
-- Cab Coose, 2018-11-09

### ***** "Espectacular!"
Realmente es espectacular esta aplicación! Poder ver los números primos y los factores primos hasta el 1 billón es súper impresionante.
-- alexmendez17, 2018-09-23

### ***** "Great app! I use it every day!"
When I write in my journal, I check every day how many days old I am, and put the prime factors in my journal. This app is perfect for that.
-- Tem Noon, 2017-02-22
