About this app

Do a decision? Make a decision.

You know the words. You just combine them the wrong way, and that is what makes English sound translated instead of natural.

Colloca teaches the word pairs that native speakers actually use together, then helps you practice them until the right combination feels automatic.

WHAT YOU GET

- 1,000 natural English collocations across 7 practical topics
- Everyday Speaking, Work & Business, Study & Academic
- IELTS & PTE Booster, Feelings & Health, Goals & Decisions, Opinions & Debate
- High-quality audio for every phrase
- Example sentences, short dialogues and common-mistake tips
- Three quiz modes: Yes or No, Multiple Choice and Spot Unnatural
- Save favorites and drill difficult phrases
- A small daily goal and streak, without pressure
- Core lessons work offline, with no ads, account or sign-up

WHY COLLOCATIONS

Learning single words stops working after a while. What separates a good speaker from a natural one is knowing which words belong together:

Wrong: do a decision
Natural: make a decision

Wrong: powerful evidence
Natural: strong evidence

Wrong: make responsibility
Natural: take responsibility

Every entry in Colloca comes with the common mistake beside it, so you learn the right pair and unlearn the wrong one at the same time.

BUILT FOR

- IELTS and PTE candidates who need stronger lexical resource in Writing and Speaking
- Professionals who want to sound natural in meetings and email
- Students writing essays and reports in academic English
- Anyone who has learned English for years but still sounds translated
