Catchword
Read full descriptionHide full description
The pharmacist says a word you don't know. You nod, and by the time you're outside it's gone. Say it into Catchword instead. In seconds you get a card - English translation, a plain explanation, and an example from that kind of moment. Then it comes back days later, right before you'd forget it. Catchword is for English speakers living in Spain, where Spanish is already part of the day - the paperwork, the landlord, the pharmacy, the school run. HOW IT WORKS β’ Hear a Spanish word or phrase and say it aloud. β’ Get an instant card with an English translation, a clear explanation, and examples from that situation. β’ Review it on a spaced schedule until it sticks. BUILT FOR LIFE IN SPAIN β’ Learn Spanish as it is used in Spain, with regional notes where they matter. β’ Keep the place or interaction where you heard each word. β’ Review a situation before you need it again. β’ No fixed course and no deck to build. WHY IT WORKS Catchword is built on the parts of learning research that survived replication, not gamified into streaks: β’ Successive relearning - the same word retrieved across several sessions over weeks. β’ Retrieval before reveal - every review asks before it shows. β’ Immediate feedback - the answer arrives the second you commit. Catchword works best alongside real life, lessons, conversations, and immersion. Reviews work offline. Audio is transcribed and discarded, never stored. Two minutes a day. A word said out loud, and it stays. --- Catchword Pro Start with a 7-day free trial, then choose Pro monthly or annual. Pro unlocks unlimited catching and review. Payment is charged to your Apple Account; your subscription auto-renews unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in Settings.

Verdict
The clearest difference is iOS requirement: Catchword at 16.4 against STEM Tutor's 18.2. On price, ads, in-app purchases and device support there is nothing between them.
