### 4/5 — Gets.chomp não pode ser executado???

*2026-07-22*

Estou estudando programação começando por Ruby e percebi que ao digitar o gets.chomp no app, ele me retorna o seguinte erro: "undefined method 'chomp' (NoMethodError)"... então queria saber se há alguma forma de ativar essa opção de interação, ou isso fica limitado apenas o programa já baixado em Windows ou Linux? Obrigado!

### 3/5 — Pls

*2026-07-14*

Pls make it so that I can require and show ruby2d

### 1/5 — Unusable, unfortunately

*2026-06-01*

There are a lot of bugs with this app now. I only made it about three minutes before giving up. When you first start coding, the keyboard pops up and pushes the code off the screen, so you can’t see what you’re writing. The screen blinks in and out frequently, like a strobe light at a concert. And as another reviewer mentioned, basic Ruby methods (not from Rails) are mysteriously missing. In sum, you just aren’t going to get anywhere with this app.

### 5/5 — Winner

*2025-11-06*

Flippin awesome.

### 5/5 — Great App

*2025-06-09*

Only thing I can say is you could have some better tutorials for beginners other than that it’s a great app

### 5/5 — Very useful for outside work!

*2025-05-11*

I must make my ruby program only by iPhone. I can do that to use this Rubylist by using iPhone 13 + ELECOM OSMOD Six + ELECOM Ultra Slim Keybord. Thanks a lot!

### 5/5 — Nada

*2025-04-15*

Nothing happening here. No longer functional.

### 1/5 — Dead, unsupported, non functional

*2025-04-11*

Dead, unsupported, non functional

### 4/5 — Some native methods not recognized

*2025-03-18*

Great scripting app for iPad.  However, there are some native methods like even and odd are not recognized by the app and i am getting method not found.  I made sure i am using an integer when I invoked the methods.

### 5/5 — Ruby scripting on iPhone

*2024-11-21*

I use this as I’m reading Ruby books. It’s a great tool to have if you want to play around with Ruby. The editor is great as well, well thought out with having the Tab button. It would be nice to have a reverse tab.
