Spicker - The Ultimate Companion for Students Spicker is German an means "crib" and that's what Spicker is, a cheating aid for stundents. Making a crib is a well know technique to memorize things because you have to deal with the subject you have to learn. Hopefully you learn that much with this tool so that you don't have to cheat in a test - and that's what I recommend you: Never cheat in a test! The features: • Add notes on your iPhone • Give the notes a colored marker • On both Apple Watch and iPhone • Adjust the font size and color on your Apple Watch • Have your notes on your wrist at any time • Learn where and when you want • Use the complication to get quick access to your notes • Enjoy nice animations • Native watchOS 2 App • Created with the latest technology Follow me on Twitter: @N1C0_MUC

Adopt-A-Float allows users to access trajectory metadata and state-of-health parameters of the EarthScope-Oceans MERMAID fleet. MERMAID, short for Mobile Earthquake Recording in Marine Areas by Independent Divers, is a long-lived drifting autonomous float equipped with a hydrophone capable of recording acoustic waveforms generated by distant earthquakes. Most earthquakes occur at or near plate boundaries, yet most seismic monitoring stations are on dry land. Deployed but not recovered, telemetering data in near-real-time, MERMAIDs are uniquely positioned as a low-cost alternative for geophysical and environmental oceanic data collection. Diving down to a typical parking depth of 1500 m below the ocean surface, they passively drift with the ocean currents, recording the ambient acoustic wavefield, identifying earthquake signals, and surfacing to report those, on average every 4-7 days with the current settings, which are expected to give them a five-year life span. When at the surface, MERMAID collects GPS location and time information and communicates with the IRIDIUM satellite constellation using RUDICS. Using this iOS app you can: View the current location of all MERMAID instruments View their most recent trajectories and obtain information about ocean depth View instrumental metadata such as battery level and instrument pressure readings Identify the instruments by name and by operating institution Developed by Tenzing Sherpa ©2021 by Frederik J Simons (www.frederik.net) Let us know what you think!

MERMAID was designed by scientists and engineers and is now built by OSEAN SAS (www.osean.fr), from which it is commercially available. EarthScope-Oceans (www.earthscopeoceans.org) is an organization founded by a multidisciplinary group of geoscientists who are coordinating efforts to create a global network of sensors that monitor the Earth from within the oceanic environment. As other organizations are doing for the land-based seismological communities today, EarthScope-Oceans shepherds national projects into the international arena where globally relevant, applicable, and mutually agreed-upon decisions can be made on instrument development, science objectives, data management, and outreach.

Verdict

The call

The clearest difference is review sentiment: Adopt at 100% against Spicker's 45%. Adopt also leads on price (Free vs $1.99) and rating (5.0 vs 3.0). Spicker's advantage is update cadence (every 4 months vs every 40 months) and ratings volume (25 vs 1). On ads, in-app purchases and device support there is nothing between them.
