AccurateClock vs TrailLog
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
AccurateClock
Read full descriptionHide full description
Accurate Clock is a focused little app for setting other clocks precisely. Why does this exist? iOS's stock Clock app deliberately doesn't show seconds, which makes it useless for the one task you really need a clock for: setting another clock right on the minute. Mechanical watches that "hack" — meaning the seconds hand stops when you pull the crown — are particularly painful to set without a visible second hand to wait on. Accurate Clock fills that gap. WHAT YOU GET • A clean analogue face with a clearly visible second hand. Toggle between smooth sweep and one-second tick. • A digital readout showing HH:MM:SS plus a smaller two-digit hundredths counter, so you can see exactly when the minute starts. • Time synchronised against Apple's public NTP server (time.apple.com) once per launch. The footer shows when it last synced and the round-trip uncertainty so you know how much to trust the displayed time. • A world time picker covering 48 cities across 31 zones — the same set as Casio's classic AE-1200 — with sectioned UTC offsets and live DST awareness. • System-aware light and dark modes. No accounts. No ads. No tracking. No data collected. WHEN YOU WOULD USE IT • Setting a mechanical or quartz watch precisely on the minute. • Setting a quartz watch or wall clock and being annoyed that you can't see the seconds. • Checking the time in another zone to help set a clock for a trip. • Just enjoying watching a second hand sweep. WHAT IT IS NOT This isn't a stopwatch, an alarm, a world-clock complication, or anything else. There are no settings beyond sweep/tick and timezone. It is deliberately small.
TrailLog

TrailLog is an app for amateur radio portable operations including World Wide Flora and Fauna (WWFF), Parks On The Air (POTA) and Summits On The Air (SOTA). It provides spots, alerts (agendas), logging, archiving and other radio related features. Spots and alerts feeds from Spotline (WWFF), pota.app (POTA) and SOTAwatch3 (SOTA). The spots feed can also show other programs including BOTA, HEMA, IOTA, SiOTA and ZLOTA (sourced from Spothole). Alerts feed shows recently past, active and future activations for WWFF, POTA and SOTA. Spots and alerts can be sent to Spotline, pota.app (spots only), SOTAwatch3 and ParksnPeaks. Logging for portable activations. Features include name and grid square lookup (via Contacts or HamQTH), quick logging of multiple callsigns, park and summit reference databases. Also allows logging of multi-operator activations. Logs show QSO count, park-to-park and summit-to-summit tags and duplicate logs. Maps show logged QSOs, nearby parks and summits, activated parks and summits, GPX tracks and custom boundaries (e.g. park boundaries). Parks and summits can be filtered based on those that you have activated or not. Watch list provides notifications for selected callsigns for conditions including: first seen, first seen today, new UTC day, change of band, change of mode, change of reference and QRT. Contacts is your address book of regular contacts. Names, alternative callsigns and grid square can be saved. The app provides propagation and space weather information. It has predictive signal tools for locations worldwide, based on real-world WSPR data. Solar indicators include SFI, SN, K-index, and geomagnetic alerts and warnings (sources: NOAA, BoM SWS and GFZ Potsdam). Archive keeps a searchable record of all logged QSOs, with ADIF import and export for backing up logs or bringing in QSOs from elsewhere. Summary tracks your activation progress for every park and summit, showing visits, activations and QSO counts against each program’s own activation rules.

Verdict
The clearest difference is device support: TrailLog at 2 against AccurateClock's —. TrailLog also leads on iOS requirement (17.6 vs 26.4). On price and in-app purchases there is nothing between them.
