Umbe - Batch File Renamer

Umbe is a focused, modern batch file renamer for iPad. Import any number of files, build a stack of rename rules, and watch the new names update live as you work. When everything looks right, hit Rename. Done. --- BUILT FOR REAL WORKFLOWS Photographers coming home from a shoot. Online sellers naming product photos. Parents finally organising years of family pictures. Document wranglers taming a folder of client invoices. These are the people Umbe is made for — people who need to rename a hundred files consistently, repeatedly, and without fiddling with the Files app one by one. --- STACK RULES, BUILD PIPELINES Every rename is a pipeline. Add as many rules as you need, in any order, and Umbe applies them in sequence to every file: • Replace Text — find and replace any string in the filename • Add Prefix / Add Suffix — prepend or append any text • Number Sequence — auto-number files with configurable start, step, padding, and separator • Change Case — lowercase, UPPERCASE, Title Case, or camelCase • Remove Text — strip a pattern from every filename at once • Date (Fixed) — stamp files with a specific date in any format • Date from Metadata — pull the EXIF date-taken from photos and use it in the name --- LIVE PREVIEW — ALWAYS ON The preview column updates the instant you change anything. You see the exact output name for every file before anything is touched. Conflicts — two files that would end up with the same name — are flagged inline in red so you can fix them first. --- PRESETS FOR REPEATING JOBS Save any rule stack as a named preset and reapply it in one click next time. Presets are stored locally on your iPad, not in the cloud. --- UNDO ANYTHING Made a mistake? One click undoes the entire batch rename and restores every original filename, right in the same session. --- NATIVE AND PRIVATE Umbe is a native iPad app built in SwiftUI. No subscription, no account, no internet connection required. Your files stay on your device. --- PERFECT FOR: • Photographers: DSC_0001.JPG → Iceland-2026-03-14-001.jpg • Online sellers: photo.jpg → ceramic-mug-blue-large-01.jpg • Document organisers: scan.pdf → 2026-03-14_invoice_acme.pdf • Family archivists: IMG_4821.jpg → 2018-Christmas-001.jpg
