Free your team from scraps of paper and forgotten items: Heynote! digitizes your order processing. With just a few clicks, you can record working hours, activities, materials used, and photos directly at the customer's site. All data is transferred live to the back office—so you always know who is working on what and can bill every order seamlessly. Here's how it works for you: • Add employees to the team: Each member records times, breaks, activities, materials, and photos; you can see everything live in the back office. The customer signs directly on site in the app – no more discussions about working hours or material usage. • Manage projects in the back office: All entries automatically end up in the right project. No more chaos with notes, no more scattered information. You keep track of what has been completed and what is still missing. • Let Heynote! work for you: The optional Heynote AI pulls all working hours, activities, and materials and uses them to create finished invoice items. Everything is complete, nothing is forgotten, no estimates – you just check and send out the invoice. Your advantages: • Complete project documentation without having to chase up information. • All items are immediately ready for billing; increased revenue because nothing is forgotten. • Personal working time and break recording as well as billable project times in one app – start/pause/stop for the day and parallel project timers for orders. • Full control in the office or on the go thanks to live synchronization between all team members. • Tracking of materials used via QR/EAN scanner. New items can be created directly in the app. • Free-text activity log with optional AI for professional invoice texts. • Photo documentation for visual logging of your work. • Digital signatures lock entries; once signed, they are read-only and marked in the back office. • AI-powered invoice templates at the touch of a button, exports as CSV/XLSX, and planned accounting integrations. Heynote! supports German, English, Polish, and Turkish (more to follow soon) and offers a 30-day free trial. All data is encrypted during transmission and stored in Germany. Whether you're a single user or part of a team, Heynote! helps you reduce paperwork, avoid errors, and increase your revenue. Please contact us if you have any questions or would like to know how Heynote can help you achieve significant sales growth.
Yappy

Share an article, a PDF, an EPUB, a Word file or a video with Yappy, and a parrot reads it to you in a natural voice. While you cook, while you walk, or with your eyes closed. Everything happens inside your iPhone: nothing ever leaves it. NO CLOUD, NO ACCOUNTS, NO PER-CHARACTER FEES The voice is synthesised on your device by an open model of about 99 million parameters. No sign-up, no email. It works offline, forever. 31 LANGUAGES AND TEN VOICES, ALL OF THEM POLYGLOT English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Romanian, Swedish, Danish, Finnish, Estonian, Lithuanian, Latvian, Croatian, Slovenian, Slovak, Czech, Hungarian, Greek, Bulgarian, Ukrainian, Russian, Turkish, Arabic, Hindi, Indonesian, Vietnamese, Korean and Japanese. Texts with quotes in another language switch on their own, paragraph by paragraph. SHARING IS THE DOOR From Safari, Mail, Files or any app: tap Share and choose Yappy. The page cleans itself up (menus, banners and footers gone) and what is left is the prose, with its headings and its rhythm. YouTube videos are listened to like articles. PDFs and EPUBs arrive with chapters. Voice notes are transcribed on the device. THE SCRIPTWRITER: FROM WHAT IS WRITTEN TO WHAT IS SAID Reading aloud is not spelling out. "1492" is said "fourteen ninety-two"; "Henry VIII" is said "Henry the Eighth", but "Louis XIV" in French is "Louis quatorze". Yappy turns every text into a reading script with the rules of each language, and the voice follows it sentence by sentence while the text lights up on screen. THE SCREEN IS THE BUTTON Tap anywhere to pause, swipe to skip a paragraph, slide along the edge to change the speed. And from the lock screen or your headphones, like any other player. THE PRESS: WHOLE BOOKS AS AUDIOBOOKS Leave a book rendering when you go to bed and wake up with an audiobook with chapters in your library. With the bridge, your Mac or PC can convert it for you and send it back on its own. TRULY FREE, AND A WIND-UP PARROT Yappy is open source (MIT licence). The free parrot carries three documents at a time on its perch; remove one and another fits, with no time limit. If you want a bottomless perch, the audiobook press and the bridge to your computer, wind it up with Yappy Parlanchín: a monthly or yearly subscription, or a single lifetime purchase. Cancel whenever you like. Subscriptions renew automatically at the end of each period unless cancelled in your Apple account at least 24 hours before.

A philologist who wanted to listen to what he read, and a six-year-old who wanted to play with the parrot.
