Polidict for iPhone: offline learning, trainings, and the full vocabulary workflow

We did not build the Polidict mobile app as “just another screen for the website” or as a thin wrapper around the web version. The idea was simpler and more important at the same time: to give you a full vocabulary-learning tool on your phone, one you do not want to close after ten seconds.

In real life, people do not study words only at a desk. They open an app in transit, between calls, in a queue, during a short break, or in the evening when they have no energy left for a laptop. That is why mobile Polidict needs to cover more than one narrow task. It has to support the full cycle: adding words, organizing material, training, review, statistics, reminders, and working without stable internet.

This article walks through what mobile Polidict can already do, how it differs from a simple “mobile version of the site,” and why, for many users, the phone becomes the main place where vocabulary work actually happens.

One important note: the app is not in the App Store yet. Right now it is available through TestFlight:

This is a beta build, so some interface details may still change.

If you care not only about the interface but also about the learning logic underneath it, the next good reads are our breakdown of FSRS v6 in Polidict and our article on vocabulary mastery.

It feels like a real iPhone app, not a site in a shell

The first thing you notice about mobile Polidict is that it behaves like a real iPhone app. You feel it most clearly in the little details that either make an app pleasant to use or instantly reveal that it is “just a website in a container.”

In mobile Polidict, we lean on system-native patterns where they genuinely improve the experience:

• system lists, forms, toggles, time pickers, and modal elements;

• iOS-style headers, SF Symbols, and glass-like header effects where available;

• haptic feedback in buttons, segmented controls, cards, and key actions;

• system interactions such as action menus, share sheets, and natural screen-to-screen navigation.

This is not decoration. These are the things that make the app fast, familiar, and easy to use every day. You do not spend extra attention on the interface. You just open the app and work with words.

Getting started in the app

One of the first strengths of mobile Polidict is that it does not make you fight through a long sign-in barrier right away. There is a proper onboarding flow that briefly explains the core idea: vocabulary, training, review, and gradual growth of your working vocabulary.

After that, you can:

• sign in with Google;

• sign in with Apple on iOS;

• use email sign-in via link;

• or start without an account in guest mode.

That difference matters. If someone simply wants to try the product and start learning words, they do not need to commit to registration immediately. And if they decide to sign in later, the mobile app already has a clean path to carry that experience forward.

Languages matter too. In the profile, you can manage the app language, the language you study, and your native language. For a vocabulary product, that is not a minor detail. It is the basis for the right context around definitions, translations, and training.

What you can do with words in mobile Polidict

The mobile app is not only about “doing reviews.” It also covers the everyday work of maintaining your vocabulary.

In the app, you can:

• browse your full vocabulary in list or card view;

• search words;

• filter them by groups and other parameters;

• quickly open a full word card;

• add new words;

• edit definitions, translations, comments, examples, and related content;

• work with images for words;

• launch training directly from the current context, for example with active filters.

That matters for serious learning because a good vocabulary app should not only help you “run exercises.” It should also help you keep the material itself organized and usable.

Groups, structure, and sharing

Once your vocabulary starts growing, everything quickly spreads out unless you have structure. That is why mobile Polidict includes full group management.

In the app, you can:

• create groups;

• search for and open the ones you need;

• edit them;

• add words to groups;

• delete groups;

• manage private or public access;

• share public groups through the system share sheet.

This is useful for more than simply “putting things into folders.” Groups directly affect how you study in Polidict. You can run training only for a specific set of words, keep separate themes, exam collections, professional vocabulary, or temporary sets for a very specific goal.

Ready-made collections and a faster start

Another strong part of the mobile app is ready-made collections, which let you start without building everything by hand.

Mobile Polidict has a dedicated screen for browsing those collections. You can filter them by topic and difficulty, view them in the context of your study language and native language, and open the ones you need without unnecessary friction.

This works especially well in two common situations:

1. When you do not want to build your vocabulary from scratch.

2. When you need to get into a new topic quickly: work, travel, everyday life, exams, or professional vocabulary.

And if you need large-scale import from your own sources, the mobile app does not leave you stuck. It leads you to Polidict’s import flow, where that task is easier to handle.

All core training modes are already on the phone

Mobile Polidict is not reduced to one format like “a card and a next button.” It already includes the full set of core training modes:

• mixed training;

• quiz mode with answer choices;

• flashcards;

• writing;

• speaking;

• listening;

• matching.

This matters for the same reason we discuss in other articles: a word does not collapse into one skill. You may recognize it but fail to spell it. You may know the meaning but stumble when you have to produce it out loud. That is why the mobile app supports different ways of testing knowledge instead of squeezing everything into one template.

Another advantage is that training on a phone feels natural: quick launch, compact interaction, haptic feedback, smooth flow between exercises, and less unnecessary noise than in many generic language-learning apps.

Speaking, listening, and where mobile really helps

A phone is strongest not when it copies the desktop, but when it does what a phone naturally does better. In language learning, that mostly means audio and speech.

Mobile Polidict uses that directly:

• there are dedicated listening exercises;

• there are speaking exercises with microphone access;

• the app handles system permissions for speech-related features;

• audio and pronunciation are built into the learning flow rather than bolted on.

That is why the phone is not a backup option here. Often, it is the best environment for daily practice. The things you postpone on a laptop can be done immediately on your phone: a quick listening review, one round of speaking practice, or a few minutes of mixed training on the way somewhere.

Statistics, progress, and reminders

A good mobile app should not only open exercises. It should help you keep a learning rhythm. In Polidict, a few things matter especially here.

First, there are statistics. In the mobile app, you can open a dedicated statistics screen and look at actual learning dynamics instead of living with a vague feeling that “I guess I studied something.”

Second, there are reminder settings. You can turn reminders on and choose a convenient time for daily practice. This is not magic, and it is not gamification for its own sake. It is simply a way to reduce the distance between the intention to study and the act of actually doing it.

Third, the profile keeps the key things close at hand: languages, account settings, reminders, and the other routine settings that should be easy to reach on mobile.

Offline support that actually works

One of the biggest strengths of mobile Polidict is that it genuinely supports offline work in the core learning flow.

The app includes:

• a local database on the device;

• local storage of vocabulary, groups, and training results;

• a queue for unsynced changes;

• two-way sync;

• offline training generation and offline training saving for key scenarios;

• clear messaging and fallback behavior when there is no connection.

Put simply: if you are temporarily offline, the app does not “break” and turn into an empty shell. You can still keep going. And when the connection comes back, your changes sync. That is exactly how it should work: offline mode should not feel like a separate “emergency mode.”

For a mobile product, this is critical. People study languages in the subway, on flights, in buildings with poor signal, while roaming, or just between unstable networks. If the app cannot handle that reality, it loses before a user even gets the chance to judge the learning method itself.

Who this app fits best

Mobile Polidict is especially good for you if:

• you want to learn words in short but regular sessions throughout the day;

• you do not want to depend on constant internet access;

• you value the feel of a real iPhone app instead of a website in an app shell;

• you take vocabulary seriously and want more than flashcards: groups, filters, statistics, and different training modes;

• you want one mobile tool for adding material, reviewing it, and tracking progress.

Conclusion

Mobile Polidict is not a secondary companion product and not a stripped-down version of the main service. It is a full app for everyday vocabulary learning, combining:

• the feel of a real iPhone app;

• full vocabulary management;

• groups and public sharing;

• ready-made collections for a faster start;

• all core training modes;

• speaking and listening on the device where they make the most sense;

• statistics and reminders;

• a practical offline flow with later sync.

Put briefly, the idea is simple: your phone should not be the place where you “sometimes review a few words.” It should be a real learning tool. That is how we think about mobile Polidict.

There is one more important thing worth saying: feedback, suggestions, and critical comments are not only welcome here, they are genuinely encouraged. Since the app is currently distributed through TestFlight, real-world feedback from people going from installation to everyday use is especially valuable.

You can send feedback in two simple ways:

• through TestFlight;

• by email at support@polidict.com.
