Instead of plain text cards, every card in its ready-made 'BrainPods' carries a picture, an example sentence and recorded audio, so a word or concept arrives with several anchors at once. The app is free on iPhone and Android, requires no account to start, and is designed for short daily sessions rather than long cramming blocks. The study method is straightforward. You see a card, try to recall its meaning before flipping, then rate how it felt — Again, Hard, Good or Easy — and that rating decides when the card returns: tomorrow, or weeks from now. Sessions are kept short, at most around ten cards with reviews first, so spaced repetition does the heavy lifting. Topics range from languages such as German, French and Spanish to science subjects like Physics, Biology, Astronomy and Computer Science, plus practical English like phrasal verbs and idioms, each split into levels. The optional Premium tier adds Mira, an AI coach that reads your study history. Mira produces a Learning Score, identifies your weak spots, surfaces insights and builds a plan for the day — for example, telling you to review ten Physics cards first. Premium also removes ads. Everything else, including every BrainPod, custom deck creation and spaced-repetition reviews, is free. **Pricing & Plans:** Braintain uses a freemium model. The app is free to download and use on iPhone and Android, with all BrainPods and study features available at no cost and no account required to start. Premium is an optional monthly or annual subscription purchased inside the app through the App Store or Google Play; it adds Mira, the AI coach (Learning Score, weak spots, insights and a daily plan), and removes ads. - **A picture and audio on every card:** Every BrainPod card has its own picture, an example sentence and recorded audio, giving your memory a visual and auditory hook instead of just text. - **Spaced repetition that sticks:** Reviews are scheduled just before you would forget a card, so recall strengthens with minimal daily effort rather than last-minute cramming. - **Ready-made BrainPods:** 47 ready-made BrainPods span languages, science, everyday English and more, each organized into levels so you can start where you are. - **Mira, your AI coach:** Premium adds Mira, an AI coach that reads your study history to give a Learning Score, highlight strengths and weak spots and propose a plan for today. - **Custom decks:** Write your own cards and add images; they receive the same reviews and audio treatment as the built-in BrainPods. - **Habit-building extras:** Motivation tools such as badges, streaks, a home-screen widget, app badge and reminders keep the daily habit going. **Strengths:** Picture, example sentence and recorded audio on every card aid memory; Spaced repetition schedules reviews at the right moment; All BrainPods and core study features are free, with no account needed to start; 47 ready-made sets across languages, science and practical English **Limitations:** Premium (Mira AI coach, ad-free) is a paid subscription bought in-app through the App Store or Google Play; Free access is limited to the mobile apps, with no desktop or web study client; The 47 ready-made BrainPods are a curated set rather than an exhaustive catalogue of every subject; No account is needed to start, but syncing progress across devices still relies on the mobile ecosystem [Profile (Markdown)](https://openaitools.app/tool/braintain.md) ## Flexi Flexi removes the tedious part of vocabulary study: typing out cards. You enter a word or paste in your own list, and the app suggests up to five ready-made cards with translations, example sentences, parts of speech and audio pronunciation. You keep the ones you want and move on. Existing decks from Anki, Quizlet or CSV files import cleanly, so you do not lose years of accumulated progress. Retention is handled by a spaced repetition system that surfaces each card just before you would forget it, pushing vocabulary into long-term memory rather than cramming for a single test. Pronunciation support spans 20+ languages with IPA, kana or pinyin displays, and an in-card AI tutor can answer questions or give feedback while you review — effectively a language mentor inside every flashcard. Beyond the core loop, Flexi adds habit mechanics that matter for daily study: smart reminders, interactive home-screen widgets for saving words on the go, and the ability to generate a custom card set for any topic. The app reports 49k+ learners, 5M+ cards created and a 4.7 store rating, and reviewer feedback focuses on how quickly new words can be added and how well the algorithm times reviews. **Pricing & Plans:** Freemium.
