PDF Offline Studio
How to use every tool, step by step, with a search box.
Drew a black box over something and want it actually gone? Use Redact rather than the drawing tools — drawing covers text, it doesn't remove it, and anyone can still select what's underneath. Redact rebuilds the pages so the text is genuinely not there. Marks moving or disappearing when you send a file to someone? Use Flatten PDF first; until you do, a signature or note is a separate object the recipient can drag around. Can't open a file? A password-protected PDF asks once and forgets the password immediately, so it will ask again next time — that's deliberate. For anything else, just email me.
Call My Meeting
Alarms not firing? Make sure Calendar and Alarms are allowed for the app in Settings, and that the app has been opened at least once so it can schedule ahead. For anything else, just email me.
Route Reel
Photos not showing up on the map? Route Reel places stops using the GPS location saved inside each photo, so make sure you grant Photos access (with location) and that the photos you pick actually have location data — screenshots and edited copies often don't. If a trip looks empty, try photos taken on the device with location switched on. For anything else, just email me.
Missed Flight
Progress not carrying to a new device or after reinstalling? Missed Flight syncs your coins, daily streak, and unlocked airports through iCloud — make sure iCloud is turned on for your Apple ID (Settings ▸ your name ▸ iCloud) and that you're signed into the same account on both devices. Tips from the Tip Jar are handled by the App Store; they're a thank-you and don't unlock anything, so there's nothing to "restore." Not getting your daily streak reminder? Allow notifications for the app in Settings. For anything else, just email me.
MealMetrics
A food named wrongly? Tap it on the review screen and correct the name — the correction drives both the database match and the breakdown, and the app remembers your version next time. Portions can be edited the same way; where accuracy matters, weigh the food and type the grams. Something packaged, like a protein bar or a shake? Scan the barcode instead of photographing it: the numbers come off the label, it's exact, and barcodes never count towards your daily allowance. "That's today's allowance" means the fair-use limit for the day; it resets at midnight, and barcodes and search keep working. Meals not appearing on another device? Your records sync through your own iCloud, so both devices need to be signed into the same Apple Account with iCloud Drive on; meal photos stay on the phone that took them and are not synced by design. Nothing in Apple Health? Health access is optional and off until you allow it, in Settings ▸ Health ▸ Data Access. For anything else, just email me.
Ja bitte
Sure an answer was right but it was marked wrong? On devices with Apple Intelligence, tap Check if I was right: if the on-device model agrees, it counts. Elsewhere, I was right, count it counts it after you confirm; that only changes your progress on this device. Either way, please email me the question and your answer (Send feedback in About) so I can accept it for everyone. No Explain button? It needs a device with Apple Intelligence switched on in Settings. Progress not on your other device? Progress is kept on each device for now. Robotic voice? Download a German Premium voice in Settings ▸ Accessibility ▸ Spoken Content ▸ Voices ▸ German (on a Mac: System Settings ▸ Accessibility ▸ Spoken Content). Change your level from the button at the top of the home screen; B2 is on its way. For anything else, just email me.
