CTEK APP The CTEK APP keeps you on top of all your compatible CTEK charging products, right there in the palm of your hand. Quickly installed and simple to use, the CTEK APP syncs your CTEK products to your smartphone via BLUETOOTH® and Wi-Fi, or by using BLUETOOTH® only.* From the clear, easy to read home page you can check the status of all CTEK products that are within range and unlock extra product features to give you even more control. It’s designed to work effortlessly with all compatible CTEK products, including the NJORD® GO portable EV charger** and the CTEK CS ONE smart charger. Get the most out of your NJORD® GO EV charger The CTEK APP gives you total control over how and when you charge your EV with your NJORD® GO. Simply connect it to the app over BLUETOOTH® or Wi-Fi and you can: • Access additional NJORD® GO features and functions • Start, stop and pause charging remotely, and enable or disable auto start • Schedule charging for any time of day • Increase or lower the output current during heavy domestic power usage • Record and display your entire charging history Open up additional features on your CS ONE smart charger • Connects automatically over BLUETOOTH® • Revive deeply discharged batteries using the ‘RECOND’ reconditioning mode • Select ‘LITHIUM WAKE UP’ for lithium-ion batteries with Under Voltage Protection (UVP) • Turn your CS ONE into a 12V power supply using ‘SUPPLY’ mode to support the battery during service work • Displays charger voltage and amperage All you need in a single app The CTEK APP also gives you access to a range of additional functions, including: • Quick connection to the CTEK customer support team • Comprehensive product FAQs and troubleshooting • Easy access to terms and conditions The CTEK APP is compatible with most CTEK connected products. If you need any more information on compatibility, check the app and product user manuals or get in touch with our customer support team. What’s New • Support for CTEK CS ONE chargers • Full charging history page (NJORD GO only) • Date filtering in history page (NJORD GO only) • General bug fixes * BLUETOOTH® and Wi-Fi compatibility is subject to product type. Some connected product functions might not be available. ** We call the NJORD® GO an ‘EV charger’ but technically speaking, it’s ‘Electrical Vehicle Supply Equipment’ (EVSE) that provides a safe supply of electricity to power the on-board battery charger in your EV. Most people use the term ‘EV charger’ so to keep things simple, we’re going to use this term as well.
Rotation

Plan work rotations and the time between them. When does your next hitch start? Which certificate is coming up for renewal? How many hours remain toward your goal? Rotation brings your schedule, documents, travel plans and experience hours together, with seafarers and offshore workers in mind. SEE YOUR ROTATION AHEAD Enter a start date, days on and days off to build a repeating schedule, such as 14/14 or 14/28. Include travel days before and after your work period. The overview keeps upcoming dates close at hand. KEEP YOUR FAMILY IN THE LOOP Connect Rotation to a calendar on your device. Choose an iCloud calendar you have already shared in Apple Calendar so your family can see work and travel days. Rotation updates events when you save schedule changes and extends the twelve-month calendar when the app opens. Days off are not added as events. Maintain the connection from one device; Apple syncs the shared calendar. YOUR NEXT EVENT ON THE HOME SCREEN Add the Rotation widget to see the days until your next outbound trip, joining, signing off or return trip. Travel days are included when enabled in your schedule. Today is not counted: tomorrow is 1 day away, and the event day shows Today. Choose a small or medium widget. SCAN AND ORGANIZE CERTIFICATES Take a photo or choose a saved image or PDF. Rotation reads text on your device and suggests course names and dates. Review and correct the details before saving. The original attachment stays with the certificate and is available offline. RENEW WITHOUT LOSING YOUR HISTORY Renew a certificate while keeping its previous version and original attachment in your history. Choose which certificates are active and which should send expiry reminders. Inactive certificates remain saved without expiry warnings. Expiry dates are optional. AN OVERVIEW THAT FITS YOU Compact cards show your rotation, certificate status and hour log. Expand what you need – the app remembers your choices. TRACK YOUR HOUR GOALS Log hours and notes toward your own experience or qualification goals. See remaining hours and an estimate based on hours per rotation. Edit or delete goals when your plans change. Entries are personal records, not official certification or verification of qualifications. KEEP TRAVEL DETAILS TOGETHER Add flight and hotel bookings with dates, notes and booking references. Enter details yourself; Rotation does not book travel or import reservations automatically. AVAILABLE OFFLINE Use your schedule, documents and hour log offline on iPhone and iPad. No separate account is required. Optionally save backups to your own private iCloud Drive folder and restore by importing a file. Backups do not automatically sync app records between devices. FOURTEEN DAYS TO TRY IT Try all features free for 14 days. Continued use then requires an optional one-time purchase for permanent access. Your local price is shown in the app before purchase. No subscription and no automatic charge when the trial ends. Your saved information remains and can be exported without a purchase. Available in English, Swedish and Norwegian Bokmål. Add your rotation and try it for your next work period. Support and privacy: http://nordsnitt.se/rotation/

Verdict
The clearest difference is in-app purchases: CTEK App at none against Rotation's 2. Rotation's advantage is update cadence (every 5 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
