Do polls at once with live audiences and use this simple app in academic lectures, industry workshops or other events for instant feedback, evaluations or votings. Just initiate a poll and share a code with the attendees who also need the app. There's no registration or login necessary. Voting is completely anonymous and people can just answer A, B, C or D. You see the results in realtime on your phone. Every poll will be closed after 30 minutes. This app is for free! Furthermore, it comes along with an in-app purchase that allows you to organize all polls that you have initiated, however, the free version works stand-alone already. I have developed it for personal use and it's very rudimental (or reduced to core features if you prefer this expression). Feel free to give suggestions for improvement.
Stud Finder®
This utility app uses your iPhone's magnetometer to detect metal studs behind walls. Simply hold your device near the wall and observe the indicator for changes in the magnetic field. For best results, remove any external case from your phone.
- Detect metal studs
- Uses magnetometer
- Measures magnetic field
- Indicator for metal proximity

Verdict
The clearest difference is review sentiment: Poll At Once at 50% against Stud Finder®'s 8%. Poll At Once also leads on rating (4.7 vs 4.4) and iOS requirement (8.0 vs 15.1). Stud Finder®'s advantage is update cadence (every 5 weeks vs every 8 months) and ratings volume (23K vs 63). On price, ads, in-app purchases and monetization model there is nothing between them.
