### 1/5 — Five stars would recommend

*2026-01-09*

Yes it says one star but i want to be the first one star. But there is nothing bad about the app, i like it. So I would recommend.

### 3/5 — Buttons bug out as 4-10 presses are required to register

*2025-12-07, version 1.2.5*

Title

### 5/5 — Better than Duolingo

*2025-11-26*

Best language learning app I’ve used by far. Better than Duolingo by a long shot!

### 5/5 — Great app for learning!

*2025-06-26, version 1.2.5*

i originally picked this up to learn Toki Pona, but I've also ended up learning stuff like the NATO Phonetic alphabet, Finnish (vocab), and Minecraft Enchantment Language.

If you want to learn extra stuff that is not apart of the app, you can also join the Discord and download Packs!

### 5/5 — I love it!

*2025-05-26, version 1.2.2*

I am trying to learn toki pona and when I go on Optimem it really helps my learning!

### 4/5 — Good for Toki Pona; Like Anki but has smaller deck base

*2025-05-03*

The best part is that its free and has no ads.(AnkiMobile $25)
Edit: Best app for a clean interface for learning Toki Pona with SRS!!!
It uses a similar format to Anki but only has two buttons: hard and easy. I prefer Anki's customizability and I like the user-friendly format, but I didn't see any sentences and often other specialized apps would be better: The main iOS toki pona app, renshuu or lingodeer for japanese, etc...
However minecraft enhantment table isa unique language I havent seen
The description says you can learn anything, but the deck selection is very limited.
Honestly has potential, but is still primitive.
Disclaimer: I only used it for about 10 min and based my review off of that.

### 5/5 — Amazing

*2025-04-21, version 1.2.0*

Very useful and simple!

### 5/5 — Awesome app

*2025-01-09*

Best language learning app I’ve used so far. Highly recommend, especially if you need to learn quickly.

### 5/5 — Yes

*2024-11-05*

I now speak Minecraft enchantment table

### 2/5 — Too confusing

*2024-07-05*

I’m trying to learn the hiragana alphabet, and often it’ll turn “Myu” into “Myo”??? Way too confusing and it causes me to fail a lot 
(*´Д｀*)
