COOLISTS — COLLABORATIVE LISTS MADE SIMPLE Stay organized, collaborate with the people around you, and never lose track of what matters. Coolists is the list app that brings your personal tasks and shared projects together in one clean, fast, and intuitive place. Whether you are managing a grocery run, planning a move, organizing a team project, or keeping a daily task list, Coolists adapts to your rhythm without getting in the way. BUILT FOR REAL LIFE Creating a list takes just seconds. Give it a name, choose an icon, pick a color, and start adding items right away. Every item can hold a title and detailed notes, so you always have the context you need — no switching between apps, no lost information. The interface is clean and minimal by design, keeping distractions out and your focus where it belongs. Your data is always with you. Coolists is offline-first, meaning it works without an internet connection and syncs automatically the next time you open the app. Whether you are on the subway, in a basement, or somewhere with spotty signal, your lists are always accessible and up to date. SHARE AND COLLABORATE IN REAL TIME Lists are more powerful when they are shared. Invite a friend, a partner, or a colleague to any of your lists with a simple shareable link. Everyone in the list can add items, check tasks off, and see each other's changes appear in real time, no manual refreshing, no version conflicts. The activity log tracks membership history so you always know who joined and when. At a glance from the main screen you can see how many items each list contains and how many have already been completed. SECURE SIGN IN Coolists supports sign in with email-based authentication, keeping your account safe without requiring unnecessary personal information. Your lists travel with you automatically across all your devices from the moment you sign in. COOLISTS PREMIUM For users who need the full experience without any restrictions, Coolists Premium is a monthly subscription that unlocks every feature in the app. Unlimited Lists The free plan supports up to two lists. With Premium there is no cap, create as many lists as your life requires, from personal errands to complex multi-step projects. Unlimited Items The free plan allows up to three items per list. Premium removes this limit entirely, so no list is ever too long and no project too large to manage. Advanced Collaboration Free accounts can invite one collaborator per list. Premium lifts that restriction, letting you build shared lists with teams of any size. Everyone contributes, everyone stays in sync. Deadlines and Reminders Set a due date on any item and choose exactly when you want to be notified, at the moment of the event, fifteen minutes before, one hour before, or even a full day in advance. Coolists sends a push notification at precisely the right time. You can also add any deadline directly to your calendar with a single tap, keeping everything in one place. Attachments Attach a photo, a video, or a file from your library or file system directly to any item. Whether it is a receipt, a reference image, or a supporting document, the attachment is stored securely and always available when you open that item. Ad-Free Experience Free users see occasional banner and interstitial ads that help keep the app free. Premium users enjoy a completely uninterrupted, ad-free interface from top to bottom. PRIVACY Coolists collects only what is strictly necessary to make the app function. Your lists, items, and account data are stored securely. The app does not sell your information or use it for third-party advertising. The full privacy policy is accessible directly from within the app. PRIVACY POLICY AND TERMS OF USE Below are links to our privacy policy and terms of use: Privacy Policy: https://handyapps.es/apps-privacy/privacy.php?app=Coolists Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: Nitro PDF Pro at none against Coolists's shown. Coolists's advantage is update cadence (every 2 weeks vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Nitro PDF Pro sells 2 in-app purchases, starting at $19.99 per year and Coolists sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
