## Most critical reviews (6 lowest-rated)

### 4/5 — Great concept, BUT

*2026-07-07*

there is an issue with the app, whenever I try to input a number in the custom sequence… it doesn’t work. Also there is no way to input negative numbers

### 5/5 — Greatest App Of All Time

*2026-02-06*

Genuinely, the things I would do just be able to use this app one more time. It is impeccable, the epitamy of perfection all an a square pixel on my phone screen. Every time I not think of using the app, my stomach does 6.whole mini loopty-loops. The is really just no doubt the greatest app I have ever used, am using, or will ever use.

### 5/5 — An immaculate and fully functional app

*2025-12-06*

A truly wondrous tool which brought my dreams into reality. Never in my life did I actually think I’d be exposed to such a beautiful algorithm presented in such a simple, and organized way.

### 5/5 — Best app to use to explore collatz

*2025-12-06*

Using the regular calculator for collatz is quite tedious, so this app saves a lot of time.

### 5/5 — Incredible app

*2025-12-05*

This app allowed me to quickly and efficiently calculate my Collatz Conjecture curiosities

### 5/5 — ABSOLUTE CINEMA

*2025-12-04*

Great for all my collatz sequence needs
