"Is this translation really right?" Sending a message to an international colleague, replying to an English email from a client, wondering if you can just send that machine-translated text as-is — TransLoop is here for the moment you want to double-check a translation, right from your phone. ■ Simple to use 1. Enter the text you want to check 2. Tap "Translate & Check" 3. If the meaning has drifted, you'll see a yellow or red signal ■ How TransLoop works (translation self-check) Once a translation is produced, TransLoop looks only at that translation and translates it back in the opposite direction, then compares it with your original text to see if the meaning still matches. Because the back-translation is done without seeing the original, the check stays objective and free of assumptions. ■ Who it's for - Anyone who emails or chats with international colleagues day to day - Businesses handling visitors from abroad, or multilingual social posts and signage - Language learners who want to check their own English writing - Anyone who wants to make sure they've correctly understood a document from overseas ■ Your translations become a growing knowledge base Translations you've checked can be saved to My Dictionary. From then on, whenever a similar sentence comes up, TransLoop automatically looks up and reuses your saved wording in the translation. Words are always applied wherever they appear, and longer phrases are automatically suggested in similar contexts — so the more you use it, the more the results sound like you (or your workplace). No more retyping the same terms every time. ■ Supported languages Japanese to/from English, Chinese (Simplified), Korean, Vietnamese ■ Plans Free: up to 5 checks/day, 500 characters per check, 50 My Dictionary entries Premium: up to 100 checks/day, 2,000 characters per check, unlimited My Dictionary ■ Premium (auto-renewing subscription) New subscribers can start with a 7-day free trial (monthly or annual). - TransLoop Premium (Monthly) — auto-renewing subscription, billed every month - TransLoop Premium (Annual) — auto-renewing subscription, billed every year (equivalent to 2 months free versus paying monthly) Prices are shown in your local currency on the purchase screen before you buy, and will be charged to your Apple ID account at confirmation of purchase (or, with a free trial, when the trial ends). Unless canceled at least 24 hours before the free trial ends, the paid subscription starts automatically when the trial ends. The subscription automatically renews for the same term and price unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage your subscription and turn off auto-renewal in your device's Settings > Apple ID > Subscriptions.

Verdict
The clearest difference is ads: TransLoop at none against Duet Display's shown. TransLoop also leads on update cadence (every 9 days vs every 3 weeks). Duet Display's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
