AkustikApp by objectiv is a precise sound measurement app for iOS, developed in Germany. It supports sound, noise and room acoustics measurement, evaluation and documentation. The app provides a professional measurement tool with RTA display for sound and noise measurement. Measurement values can be saved as screenshots and used for documentation. This makes AkustikApp suitable for capturing acoustic situations in offices, daycare centers, schools, meeting rooms, public spaces and private rooms. The app can also be used for orientation and documentation of environmental noise, such as traffic or aircraft noise. The integrated acoustic measurement uses the device microphone to display relative level values and acoustic characteristics. In addition, the app provides information about acoustic products and solutions, including acoustic pictures, ceiling absorbers, wall absorbers and other products for improving room acoustics.
EVENTRA (DE)

EVENTRA staffs large-scale events with AI instead of spreadsheets. Applications pre-screened, shifts proposed, hours captured, payroll exported. Note: access requires an EVENTRA company account. ROSTERS YOU CONFIRM RATHER THAN BUILD The AI drafts a proposed assignment for every shift from your team's qualifications, availability and stated preferences. You review it, adjust by drag-and-drop and approve. An afternoon of planning becomes a quarter of an hour. APPLICATIONS RANKED, NOT SCROLLED Incoming applications are scored automatically against the role, the required qualifications and previous assignments. The profiles that fit the posting surface first, even when several thousand people apply to a single event. EVENT-DAY OVERSIGHT Who has clocked in, which shift is short-handed, where someone hasn't shown: status updates live on your phone. You intervene while walking the site instead of from a laptop in the production office. COMPLIANCE THAT FLAGS ITSELF Expiring certifications, gaps in accreditation and working-time limits surface before they become a problem. Digital accreditation is built in, including ZVÜ compliance for events held in Germany. PAYROLL WITHOUT RE-KEYING Captured hours are prepared for payroll with premiums and surcharges applied, then exported to DATEV or Stotax. No retyped timesheets, no queries two weeks after the event. YOUR CREW ON SITE Staff and volunteers apply in under a minute, accept or decline shift offers, clock in by QR code even with no signal on site, and check their own hours. Queries are raised on the time entry itself rather than in a WhatsApp group. PART OF THE EVENTRA PLATFORM The app extends the web dashboard: recruiting, AI-assisted shift planning, accreditation, time tracking and payroll export. More at eventra.app. PRIVACY Built in Munich, hosted in Europe, GDPR compliant.

Verdict
The clearest difference is update cadence: EVENTRA (DE) at every 6 weeks against AcousticApp's every 4 months. AcousticApp's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
