Aligna is a focused batch file renamer that cuts down repetitive renaming. Pick files, choose presets, and preview every new name before you apply changes. The 8 included presets are: - Add a date at the start - Add a date at the end - Add sequence numbers - Replace spaces with underscores - Remove invalid characters - Rename JPEG photos by capture date - Rename MP3 files as Artist - Title - Rename MP3 files as Track - Title If target names conflict, you can add numbers automatically or skip the conflicting files. The free version can rename up to 10 files per operation. A one-time Pro purchase removes only this file-count limit; all 8 presets remain available in the free version. On Android, supported files are renamed in place within the access you grant. On iOS, originals selected in Files are renamed in place. Imported copies are saved as new files. No account, ads, subscription, or cloud file processing. Aligna does not upload your files to an external server for renaming.
Explorer

Explorer turns your iPhone into a full sensor logger. Start a session and it records your GPS track together with barometric pressure, compass heading, motion and activity data, step counts, and battery state — in the foreground or with the screen locked. YOUR DATA STAYS YOURS Everything is stored on your device. No account, no analytics, no ads, no third-party SDKs. Data leaves your phone only when you export it — and you choose where it goes. RECORD • One-tap session recording with live dashboard: position, speed, altitude, G-force • Background tracking that keeps logging while your screen is off • Log points of interest with a tap - or hands-free with Siri: "Log a POI in Explorer" • Per-sensor controls and sample rates to balance detail against battery EXPLORE • Every session drawn on the map in its own color, with POI pins • Live compass, motion, and environment views • Browse every reading in the Data viewer with filters and charts • Preview any session on a map before deleting it EXPORT ANYWHERE • Share ZIPs of CSV or JSONL via Files, AirDrop, or Mail • Or send data straight to your own server: any HTTP(S) endpoint, POST or PUT, custom headers, Bearer/Basic/API-key auth — credentials kept in the iOS Keychain • Filter exports by sensor type, session, and date range • Full schema documentation built into the app (Help → Data Reference) Explorer asks for location (including Always, for background recording) and motion permissions. Recording happens after you tap Start Tracking or open the app.

Verdict
The clearest difference is in-app purchases: Explorer at none against Aligna's 1. Aligna's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
