In the additional screen on performance calculation, you can calculate all relevant performance values such as torque, metal removal rate, main processing time, performance, cut arc angle and specific cutting forces, by selecting the corresponding material and entering additional production parameters. TPC milling (Trochoidal Performance Cutting) Calculate the relevant parameters for your application using a few entries. In this case, it is possible to calculate the cutting width, feed rate per cutting edge, cut arc angle and the maximum cutting thickness. The Hoffmann Machining Calculator is now also available in 16 languages: German, Hungarian, Czech, Spanish, Slovenian, Swedish, Russian, Romanian, Polish, Dutch, Italian, French, Finnish, English, Danish and Chinese.
Ear Prompter

Copy arrives late. The lens still needs your attention. Ear Prompter is for actors working with commercial copy, industrial and corporate scripts, hosting intros and their own pieces to camera. Record a guide in your own voice, hear it through headphones and rehearse your delivery on iPhone or iPad. PRACTISE WITHOUT BUYING A DEDICATED RIG Start with your phone, headphones and a short passage of copy. Record a relaxed read, listen back, then try speaking with it in your ear. Ear prompting takes practice. Give yourself a few goes to find the rhythm and make the words your own. A GUIDE THAT FOLLOWS YOU A recording on repeat keeps playing at its recorded pace. Ear Prompter uses on-device speech recognition to follow your place in the script and adjust your guide as you speak. Choose whether your read leads by a few words or a whole sentence, which ear hears it and how loud it plays. FROM COPY TO TAKE - Write or paste your script, or try the sample. - Record and keep a guide read in your own voice. - Listen through headphones and rehearse the passage. - Start an audio take and keep going with the screen locked. - Make a video take with the camera as the stage and the script off screen unless you choose to show it. - Play back your take. Try a different emphasis. Go again. For commercial self-tapes, a hosting reel or a solo shoot, practise keeping your attention on the lens instead of a page beneath it. If you change the words, make a new guide read to match. START FOR FREE Free includes 3 reads, 3 listens and 3 kept takes per script: 1 script without an account, or 3 when signed in. The sample script does not use a script slot. Playback of saved reads and takes remains free. GO FURTHER WITH PRO Pro removes the rehearsal counts and adds sharing and saving takes, plus script sync with your account. Library and device storage limits still apply. Takes made before the 1.1 update remain exportable. Pro is available as a three-month subscription, a yearly subscription or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel subscriptions in your App Store account settings. Headphones are required. Available for iPhone and iPad on iOS 26 or later.

Verdict
The clearest difference is in-app purchases: Hoffmann Machining Calculator at none against Ear Prompter's 3. Hoffmann Machining Calculator also leads on iOS requirement (13.4 vs 26.0). Ear Prompter's advantage is update cadence (every 3 days vs every 6 months). On price, ads and device support there is nothing between them.
