Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BPM MS FPS
Read full descriptionHide full description
This is a simple converter that calculates the length in MS and FPS-frames according to musical note duration noted as proportion of a bar. Choose BPM (tempo) and overall FPS - and voila! Definitions MS - milliseconds FPS - frames per second BPM - beats per minute It might be 'useful' to some people to have a stand-alone app for doing just this.

"Prime Time" is a high-precision time app that shows the true time, accurate to the millisecond. It queries NTP servers directly — the same infrastructure that keeps the internet in sync — and works out the correct time from their answers. Your device's own clock is never used for the display. [New in version 1.4] • Display Offset (Pro): run the large clock up to 99.999 seconds ahead of or behind real time, in 1 ms steps — for remote broadcasts, live streams, or any delayed feed. While it is on, the time turns yellow, with the offset above and the actual time below, so there is no mistaking it for real time. Measurements are never shifted. • Server details now use two columns in landscape on iPhone, so everything fits on one screen. • On iPhone with ProMotion, the clock now refreshes up to 120 times a second. [Free — one server, in full detail] • Real-time sync with one NTP server of your choice • Every exchange laid open: address, stratum, reference, root delay, jitter, estimated error, and the last eight exchanges • Millisecond display, refreshed up to 120 times a second on ProMotion screens • Offset and round-trip time with sparkline history • Adaptive polling that eases off as a server proves steady [Pro — one-time purchase, no subscription] • Compare up to 30 servers. With three or more, a server that is off is outvoted instead of skewing the time shown. • Manual sync on demand • Keep the screen awake while the app is open • Display Offset: run the clock ahead of or behind real time A note on accuracy: a round trip is a single number covering two unknown halves, and nothing in the exchange reveals how it was divided. Prime Time widens the reported ± rather than inventing a correction to hide it. On cellular, where the two directions are least alike, that margin is wider — and shown. Made for developers, network engineers, broadcast crews, and anyone curious about how far off their device's clock really is. Available in English, Japanese, German, and French.

Verdict
The clearest difference is price: Prime Time NTP at Free against BPM MS FPS's $0.49. Prime Time NTP also leads on update cadence (every 6 weeks vs every 4 months). BPM MS FPS's advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 26.0). On ads and device support there is nothing between them.
