"I didn't think something like this was possible, but I'm happy to say I've been proven wrong. This is a great app to have on your iPhone!"


TransKey is a keyboard extension that translates your messages inside any app (such as iMessage, Whatsapp, Email, and many more).

TransKey also works the other way around. Copy the text you can't understand and TransKey will show you what it means in your native language!


Write what you'd like to say, but before sending your message, tap and hold the Globe key to switch to TransKey. After selecting a target language, tap "Textfield" and watch your message get translated right in the app!

If you'd like to translate a message you received, tap and hold it until an option to "Copy" appears. In TransKey select "Clipboard", and the translation will appear in the same place!

Never encounter another language barrier again when communicating with people in other countries! TransKey provides a flawless translation experience right in the messaging app of your choice unlike other translators which interrupt the flow by forcing you to switch to another app.

Unlike other translator keyboards, TransKey does not have keyboard for typing. This allows you to use the keyboard you're most comfortable with, such as the iOS or Swype keyboards.

Before TransKey:
1. Exit the app you're currently using
2. Open your preferred translation app
3. Type what you need to translate
4. Copy the translated text
5. Exit the translation app
6. Open the app from before
7. Paste translated text

After TransKey:
1. Type what you need to translate
2. Switch to TransKey
3. Tap to translate


• Translate the last sentence of any text field directly within any app
• Translate received messages directly within any app
• Fast and accurate translation to and from over 100 languages
• Automatic detection of source language
• Choose between Google Translate and Yandex Translator
• Copy the translation to be used anywhere
• Optimized for all iPhone screen sizes in both portrait and landscape
• Preserves capitalization and emojis

I built TransKey by myself, so if you enjoy the app please tell your friends about it, write a review on the App Store, or send me your thoughts through the app. I'd greatly appreciate it! Best, Aleksander.


For accurate real-time translations, TransKey relies on industry leading machine-translation engines such as Google Translate and Yandex Translator.

Full access is needed to communicate with the translator, the app cannot function otherwise. We do not get access to everything you type, only the text field in focus when you are using TransKey. We do not store anything you translate, please read our Privacy Policy for further information.

Has a lot of potential

Spirit road

First, the creator of this app is very responsive and helpful. That is a huge plus in itself. I am changing my rating to 5 stars for that reason.

If you converse in other languages much, the easy use and capabilities of this app make it an excellent option. The free use is very limited, but the premium service is reasonably priced if you will use it regularly. Just be aware in advance of exactly what you are gettin: premium is a monthly or yearly fee. Don’t rate the app lower because you have to pay for the service—that’s how the app works. It’s the free part that is the extra. And it’s waaaay cheaper than most “in-app purchase” apps.

$1.99/month or less than $1/month if paid yearly...for unlimited easy, in-app translations and a developer who responds well? Definitely worth the cost in my opinion.

Developer Response

Thank you for your feedback, and I'm sorry TransKey did not live up to your expectations.

By default, you get 180 free characters per day. On average, this is about 6 translations (depends on the length of your messages). While sufficient for most, I also offer a Premium tier that features unlimited higher-quality translations.

I have tried to make this as affordable as possible, and offer two payment plans:
• The first is billed monthly at $1.99 (depending on your App Store country), and allows you to cancel and resubscribe at any time.
• The next is billed yearly at an effective rate of ~$0.8 per month. This is more similar to an up-front price, in that you pay once and don't have to think about it again. There is also a 1-week free trial, so you can give it a try and cancel at any point before it renews to avoid being charged.

At less than 1/5th the price of a small Caffe Mocha at Starbucks, I believe this option to be a great value.
However, you can also get TransKey Premium entirely for free by sharing the app with friends! For each person who downloads using your link, you get a full week of TransKey Premium. To get started, open the TransKey companion app and select "Refer Friends" in the main menu.

Hope this helps! If you have any further questions or comments, please feel free to reach me directly at hello@alekapps.xyz.


Why Do I Have To Pay???


I don’t understand why I only have a limited amount of translations per day which is really annoying. I don’t think it makes sense at all especially with the fact that this app is amazing and better than any other app out there and I don’t even think that there’s an app out there that work like this one. I wish with the regular version there was at least unlimited translation characters but instead, we just didn’t have some features that we would have with premium, you know? This app is amazing but it’s just the purchases that really get on my nerves. I’m 12 years old and I can’t afford things like this....☹️ Please fix this issue! Overall though, AMAZING APP!😁👌🏾👍🏾 KEEP UP THE GOOD WORK GUYS!

Developer Response

Thank you for the positive feedback!

To address your point regarding the pricing structure: like any business, app or not, I have operating expenses. These include server costs, development costs, marketing costs, etc.

The single biggest expense, and the reason for the pricing model, is I have to pay for every single translation a user of TransKey makes. I therefore offset that cost directly to the user making the translation.

Despite this, I strongly wanted TransKey to remain free for occasional users. As such, I included a free tier with lower quality translations, but had to limit the number of translations to make it sustainable and available to all.

I have made every attempt to make TransKey Premium as affordable as possible, and at less than 1/5th the price of a small Caffe Mocha from Starbucks per month I believe it's within reach of most people.

I understand money is tight when you're 12 years old, and as a final option you can also get TransKey Premium entirely for free by referring friends! For each user that downloads the app through your link, you get 1-week of free TransKey Premium. To get started with this, open the TransKey companion app, press "Refer Friends", input your email, and share the link! Keep in mind, users you refer need to sign up using their email as well when opening the app the first time.

Hope this helps! If you have any further questions or comments, please feel free to reach out to me directly at hello@alekapps.xyz.


Used to be amazing


Transkey used to be an amazing app that was very useful, but instead of keeping it that way they instead are now making us pay a 1.99 fee to actually use the service, otherwise your characters run out in one sentence. They said that they couldn’t sustain a free model which makes sense, but I HIGHLY doubt that making a one time in-app purchase would be worse. In fact doing a one time purchase would probably be better as the subscription is turning SEVERAL people off. Or if you need to, just run ads. Thousands of apps do it and I would like an option where you can enable ads if you don’t want to pay.

Developer Response

I'm sorry you're unsatisfied with the subscription based model, and I appreciate your suggestions. I will look into ways of improving the monetization model such that it caters to more people. Feel free to reach out to me at hello@alekapps.xyz so I can make this up to you!
