Our verdict on each
Fiszki
Fiszki suits learners who want a daily vocabulary habit across many languages rather than a single structured course, and its free tier lets them start before paying anything. The catalogue runs to 15 languages, and a 60 day refund window softens the opening paid month.
Mondly
Mondly suits beginners who want an app with speech practice, a kids version and a free plan to start on, and who are willing to pay for a yearly commitment. The yearly plan at €47.95 is the figure that makes it affordable, while the 14 days money-back period softens the risk.

Pros and cons
Fiszki
Pros
- A free tier lets a reader reach the lessons before any payment, which lowers the cost of finding out whether the format fits.
- A 60 day money-back window on a paid subscription gives a learner time to reach the point where the habit has settled rather than deciding in a week.
- 15 languages in a single account, from English, German and Spanish through to Kashubian and Ukrainian.
Cons
- The service is published for PL, so anyone outside that market should expect the terms, billing and support to be aimed elsewhere.
- Coverage is languages only, so a learner shopping for maths, music or exam preparation finds nothing beyond language decks.
- The method is app and audio, so a learner who needs a graded assignment, a marked essay or a speaking partner gets no correction from the platform itself.
Mondly
Pros
- A free tier is included, so the app can be used before any payment goes out.
- AI conversation and speech recognition are both part of the offer, which suits learners who want to practise speaking rather than only reading.
- A kids version sits in the same subscription, so a single payment covers adults and younger learners.
Cons
- The entry price of €9.99 sits above Bunpro, which lists $0.
- Support runs on email and help centre only, so a phone line is not among the options for anyone who prefers to talk.
- The monthly price of €9.99 ranks 12 of 25, so a month to month habit is the costly way to use the app.
Who each suits
Fiszki
Who it suits
- Learners who want a short daily review rather than a long course with deadlines.
- Families covering a school language, a holiday language and a heritage language such as Kashubian in one place.
- Parents who want a kids version instead of filtering an adult catalogue by hand.
Who should look elsewhere
- Learners after a certificate or a graded qualification, since the catalogue is languages and the platform is curated sets rather than assessed courses.
- Anyone studying outside PL, where the terms and billing are written for a single market.
- Learners who need a live tutor or a speaking partner, since the method is app and audio and correction has to come from outside the app.
Mondly
Who it suits
- Beginners who want to practise speaking early, since AI conversation and speech recognition are both included.
- Learners ready to commit for a year, since the yearly plan at €47.95 is the figure that works in your favour.
- Families with adults and children learning together, since a kids version is part of the same subscription.
Who should look elsewhere
- Learners who want to start at no cost, since Bunpro lists $0.
- Readers shopping for a different paid entry point, since Reading Eggs lists £6.99 to set beside Mondly's €9.99.

Questions about each
Fiszki
How much does Fiszki cost to start?+
Fiszki publishes a starting price of PLN 0.60. A free tier also exists, so a reader can open the app and work through lessons before choosing a paid plan. The starting figure is the entry point, not the whole cost of a year.
Is there a free version of Fiszki?+
Yes, a free tier is included, and it is the normal way most readers meet the service. You can open the app, run a deck and see whether the review routine is one you keep. Behind it sit 15 languages in the same curated style, and an offline download is available so a deck works away from a connection.
Mondly
How much does Mondly cost?+
Mondly's entry price is €9.99, the monthly plan runs at €9.99 and the yearly plan at €47.95. Each figure is a separate commitment rather than a single rate, and the yearly figure is what decides whether the app feels cheap. The entry price is quoted in euro, so buyers elsewhere should expect a different local amount. Checking which plan each price sits on before paying is worth the minute.
Is there a free version of Mondly?+
Yes, there is a free tier, so the app can be opened and used before any payment goes out. The paid side comes with a free trial of 7 days, so you can check the subscription features without a long commitment. Between them you get a short test of the paid side. If the free tier covers what you need, nothing has to be paid at all.
