Start building a clear private record of what happened. ProofLog helps you record what happened, keep the supporting proof with it, and build a clear private record you can return to or export when needed. Log incidents, exchanges, schedule changes, school issues, medical concerns, messages, and other important events. Add screenshots, photos, PDFs, and documents directly to the entries they support — or save files first and connect them later. Your Story and Files stay together in one organized Record, with timestamps and record history that make it easier to see what happened, what was added, and when. When communication gets difficult, ProofLog also includes focused Guidance tools to help you slow down, think clearly, and decide what to say next. WHAT YOU CAN DO • Log what happened Record incidents, exchanges, schedule changes, school issues, medical concerns, messages, and other important events while the details are fresh. • Add proof Save screenshots, photos, PDFs, and documents. Link them to the entry they support or keep them available to connect later. • Build your Record View your chronological Story and supporting Files together in one private place. • Keep a clear history See when records were created, when supporting files were added, and when entries were changed. • Export your record Create an organized PDF of your entries and supporting evidence when you need to share or review it. • Reply Calmly Turn emotionally charged messages into clearer, more grounded responses. • Set a Boundary Draft firm, respectful wording without overexplaining or escalating conflict. • Reply or Wait Think through whether a message needs a response now, later, or at all. • Talk It Out Work through a difficult situation before deciding what to say or do next. PRIVATE BY DESIGN ProofLog is built as your private record. It is not a shared messaging platform, shared calendar, or portal that another person joins. Your records remain private unless you choose to export or share them. ProofLog can be especially useful for high-conflict co-parenting, custody documentation, difficult communication, high-conflict divorce, and other situations where keeping a clear record matters. ProofLog is not legal advice, therapy, or crisis support. ## SUBSCRIPTION Start with a 3-day free trial, then continue with **$8.99/month** or **$69.99/year**.

The standard iOS keyboard takes up almost half your iPad HalfKeyboard takes about two thirds of that, so you keep seeing what you're typing into — your chat, your form, your note. But it's not a stripped-down version. Everything you expect from a keyboard is there, right where your thumb already rests. SWIPE DOWN FOR THE SECOND CHARACTER Swipe down on a letter key to get the character above it: q becomes 1, a becomes @, z becomes %. On the period key, a swipe down gives a comma. You'll rarely need the number layer. SET IT UP YOUR WAY Height, font size, key spacing, bottom row thickness, typeface — all with a slider. Both in the app and in the keyboard itself, so you see the effect right away. Settings made in the app go to the keyboard; not the other way round, because a keyboard without full access isn't allowed to write back. SPACE BAR AS A TRACKPAD Hold the space bar and drag to move the cursor through your text. No more aiming for a single letter. WORD SUGGESTIONS THAT SEND NOTHING A suggestion bar in Dutch, English or German, or automatic. The word list lives inside the app; nothing is looked up and nothing is remembered. EMOJI Its own emoji board with categories and a clock tab that fills with what you used last. ROOMIER ON IPAD On iPad you get two extra layouts: a numeric pad on the right, and a split layout with the pad in the middle and a space bar under each thumb. PRIVACY HERE IS NOT A PROMISE BUT A BOUNDARY HalfKeyboard does not ask for full access. Without that permission, a keyboard on iOS cannot connect to the internet — a technical limit, not a word of honour. No analytics, no ads, no account, no third-party SDKs. What you type stays on your device. Free, with no strings attached: no ads, no subscription, no in-app purchases.
