Super

Super, mais serait-il possible d’apprendre deux langues minimum en même temps s’il vous plait ? Je suis en licence de breton et j’apprends l’irlandais aussi. Merci

10/10

Having an app where I can *actually* learn Cornish is amazing , I love genuinely being able to explore my language

Great app for Irish!

Graduated from Duo to a new level of learning. I love the explanations of grammar and why things work the way they do. The historical is a bonus too.

A few problems

Lots to like here but the Welsh audio is incomprehensible. Also, I can’t seem to skip the basic levels. I’m an advanced learner and don’t need to drill days of the week or verbs like eat, run, go, etc, though I’m stuck on them.

Response from developer

Thanks for the honest review! On levels: the placement quiz used to cap out early in A2. The next update lets it place you straight into B1 or B2, so an advanced learner skips the basics. If you have already been placed too low, email info@blasapp.com with the Apple ID you use and I'll move you forward by hand; apologies for this! I am trying to strike a better balance between beginner learners and more advanced ones. On the Welsh audio: it comes from a Welsh-specific voice. It handles sentences well but garbles some single words, and we're replacing the worst of those. If you send me a word or two that sounded wrong, I'll fix them first.

Scottish Gaelic - Great!

Beginner to Scottish Gaelic and am using Blas. in conjunction with Speak Gaelic - Blas. complements learning well with questions, puzzles, and practice formats, and I especially like that you have to type out some answers rather than just choose a multiple choice answer from recognition.

Thanks for the great review!

NOT FOR IRISH

I do not recommend for Irish Language - This app is very good in its concept and design BUT there are too many errors in the answers and it is an extremely repetitious program which might lead beginners learning improperly- also if you are already an high level beginner or lower intermediate learner, you cannot jump to your present level and you are stuck endlessly repeating the same word- I’ve been using 3 days and I have possible had to pick or write “ól” (to drink) one hundred times - try it for free but I don’t recommend purchase until they debug this app of the errors -

Response from developer

Thanks for writing this out. I think there are three different things here. The ól loop is real. It is a core verb that sits in several early units and then comes back in review, so three days can feel like the same card forever. On jumping ahead: there is a short placement at the start. If it still dumped you on the beginner path, that is on us. Email info@blas.app with the Apple ID you use, and I will move you forward. On wrong answers: I do not want anyone drilling mistakes. If you can send one or two examples (a screenshot is perfect), I will correct them. Happy to refund if you paid. All of our language content is from open source resources, so I would heavily vouch for its accuracy.

forced free trial

the app automatically puts you on a premium free trial without letting you explore the standard version AT ALL. i do not want a free trial, as all this will do is get me used to features that will be taken away after a week.

Very great

This app is exactly what I was looking for to learn the Celtic languages. The new dictation feature is amazing - now I can speak into any app and it turns it into Irish text. It’s like taking a practice speaking lesson

Review

This has been really good for me in trying to reconnect with my roots and learn Gaeilge. I like the way it is structured on everything but my main problem is the Pronunciation part. No matter how perfectly I will mimic the pronunciation, it never picks it up and just comes up with ‘A’ ‘A’ or a word not even remotely like that I am speaking. That could do with improving.

Aside from that, keep doing what you are doing it is a good app with great potential

Response from developer

Thanks for the response! Yeah the pronunciation part is quite experimental and so is optional for users, we're working on getting a much better version of this in the future!

Audio Issue and difficulty

I am not hearing any audio phrases when being drilled on listening, though the app itself is making little accomplishment noises, so it isn’t muted. I chose to learn Cornish, and since I have some Welsh under my belt it is easier to guess answers, but the interface is clunky for finding the “lesson” portion (rather than the drills) to start as a pure beginner. I had to use a reply from these reviews to even realize where to start. Morre hand-holding is needed for learning the app’s interface. It also begs too much to start a “premium” plan, and the grammar explanations touted appear to be locked behind this paywall. It is not intuitive nor easy to use for a pure beginner. I am working on Celtic languages specifically, I had high hopes that aren’t yet satisfied by Blas.

Response from developer

The Cornish and Manx courses are free to use as they have no audio. This is because they are very low-resource and don't have a computer voice for them; we are changing this by getting human voice recordings for these languages, but this is a slow process. The app lets you know this when first starting, but perhaps I should add it elsewhere too. I am not sure exactly what you mean by "where to start". The first lesson (and all the rest) are on the first screen, at the top, on the homepage of the app. I think that some more content can be added to help bolster beginners.

Not for beginners

Even though there is the option to start as a complete beginner, I felt that the lessons did not teach enough information to follow the practise drills unless you already knew some Irish. For example, the lesson would teach you the word for ‘house’, but the practise drill would be ‘how do you say “the house is at the top of the hill”’ even though you haven’t learnt any of those other words or even the basic word order of the language. I also downloaded the app because of the Celtic-language-specific features like spelling lessons, but those assume you have lots of vocabulary already, which is difficult to learn if you don’t understand why they are spelled the way that they are. I was really excited to try this app but I just found it frustrating because I could not find the information I needed to do the exercises.

Response from developer

Hi, I know this is slightly frustrating, but the app is designed to throw you into the deep end with lessons. Exactly like how you would learn a language in real life. For example, it will give you a random beginner word in the spelling drill (eg like Labhraíonn), even if you have or haven't seen that word before, it may be difficult to spell. Having seen or spoken it in lessons prior will not make you a better speller; you need to practice writing it to spell it. Hopefully this helps! You can't learn without getting things wrong initially!

Dyslexia/Dysgraphia amazing

Compare to any language learning app out there and you will find a feature here the others lack… accessibility for those with learning disabilities in the settings. For those of us who have the above this app not only allows you to turn answers requiring spelling off it features a section to work on spelling specifically!! A creator who truly cares that folks learn to SPEAK our language! I can’t give this a higher rating!!! I wish I could!!

This will be the Duolingo killer for the Celtic languages.

Duolingo has long been the go-to for learning languages through an app, and I myself completed the Portuguese course on it years ago. Over the years, however, it has gradually come to be among the slowest methods available for language-learning, and I have completely abandoned it.

While Duolingo indeed offers many languages including Welsh, Irish, and Scots Gaelic, but it’s common knowledge that any language outside of the top most popular ones is an afterthought at best.

Blas is different. No silly childish characters, no unnecessary bells and whistles, and a slick minimalist UI. This app is how Duolingo was 10 years ago, though perhaps even more straightforward. For having been around for less than a year, it already looks and feels quite professional, and more importantly like the developers are clearly aiming to make a serious language-learning app rather than a game.

Although many features have some kinks that could be hammered out (especially the voice clips, speech recognition, and camera mode), I wholeheartedly expect this app to be the #1 for Celtic languages within the next year or two. Overall, my experience learning Welsh with it has been efficient and highly enjoyable, and I’m anxious to see how the app will improve further as development continues.

Response from developer

That's a brilliant review, thanks! There are definitely a few kinks in the app still but they will get ironed out with time hopefully. Cheers for using the app.

Best App for Irish Gaelic

This app is great for learning Irish because it covers grammar, pronunciation, and reading while combining many ways of getting you to remember and practice the language.

There are ways for the app to grow and get better (the main vocabulary drill can be a little receptive for the casual learner as of 6/2026), but the different modes of learning make me keep coming back day by day.

Definitely recommend!

Pas mal de bugs mais très cool!

Super contente d’avoir trouvé une app pour apprendre les langues celtiques (et plus particulièrement le breton), cependant l’appli plante beaucoup, et même si l’interface est bien faite j’ai quand même des mélanges d’anglais/français pour les consignes, les prononciations ne sont pas forcément bonnes et les corrections pas toujours bonnes non plus (ex: “salud! demat!” indiqué comme signifiant “salut! bonjour!” et deux slides plus tard corrigée comme “hi! good morning” - compliqué à traduire en français).
L’app est toute neuve alors c’est normal qu’il y ait des soucis, en tout cas c’est une très bonne initiative, merci!

ran into an audio issue

just downloaded the app today. it seems nice, but for some reason the audio doesn't work at all?... i tried welsh and scottish gaelic, and in both there is an audio icon next to new words, however nothing happens when i try to press it :(

Response from developer

Hi! Sorry about this, did you ever get this sorted? I have been trying to recreate it on my end, but can't find what's wrong. If you could email me at john@blasapp.com with details it'll really help!

Wow!

A good looking fine app for Gaeilge learner! Thank you 👏

Response from developer

Cheers!

AMAZING APP

As a beginner who’s always wanted to learn Cornish and Welsh, this is genuinely the perfect app. I can do both at the same time with no worries of losing progress, and the way it’s set out is just perfect, it goes over all the important areas one step at a time it’s such an amazing app !

Response from developer

Thank you very much! Good luck!

Much Better than DuoLingo

I’ve used Blas. now for a few months, in that time frame I’ve learned and retained more Gaeilge than most he entirety of my time using DuoLingo.

This app was designed specifically for the Irish (and Welsh) languages and it really shows.

The explanations of the mutations (eclipsis and lentition) are probably some of the most useful parts of the app, and also the biggest differentiator from duolingo, which just throws the mutations at you without explaining the context.

The other reason why I like the app so much is the responsiveness of the developer. Yer man there is constantly updating the app and is always happy to get feed back.

I’ve recommended this app to nearly everyone I know who is looking to learn or improve their Gaeilge and will continue to do so.

10/10, love this app.

Good learning app

I used the app for Welsh. It’s a good learning app and i especially like the puzzles and focal.

The only downside is the speech, it needs working on as it speaks a little too fast at times. The pronouncation can sound off or incorrect too. It’s my reason for four stars. But if this gets worked on then i would give the app a five star rating.

Response from developer

Cheers for the review! Yes the Welsh audio isn't brilliant, it's the only Welsh specific thing that exists at the moment for speaking. We are building our own computerised voice that'll hopefully be much better, and at the same time starting to get some native speakers in so a lot of the main course content will be human voiced.
