One world. Onetime. Finally, a world clock that integrates all time zones into one easy-to-read dial. We are all living and working globally more and more, so we needed a way to simply see the time in cities around the world at a glance. That’s how Onetime was born. Built on the metaphor of the earth’s rotation, Onetime displays all the cities that matter to you as they move through the day and night in a natural, clockwise direction referencing the international date line. Whether you are scheduling an international call or checking to see what time it is back home, Onetime is the clock for you. No more mistakes adding and subtracting hours, no more confusing GMT numbers, no more remembering daylight savings calendars. Onetime takes care of it all, automatically. And with Timetravel™, you can fly through time so that you quickly find the right moment to schedule that important teleconference with your international colleagues or catch your loved ones before their bedtimes. The „Share“ feature lets you choose a date with TimeTravel and send an invite via message or email. Give up your wall of newsroom clocks and switch to Onetime today. Onetime. By FLUID. ABOUT FLUID Onetime was created by the award-winning design firm FLUID. With our locations in Munich and Silicon Valley and our international client base, the FLUID team is a heavy Onetime user, too.

You already saved it. Finding it again is the hard part. But not if it is actually in your TopDrawer! TopDrawer is one fast drawer for the things you reuse: text snippets, links, screenshots, photos, PDFs and files. Save something from any app in two taps, then find it later by typing any word that's in it, including the words inside your screenshots. SAVE FROM ANY APP! - Share a link from your browser, a screenshot from Photos, a PDF from Files, or a bit of text from anywhere. It lands in TopDrawer. - Paste in whatever you just copied, when you tap Paste. TopDrawer never reads your clipboard in the background. - Any file type is welcome. Nothing gets converted, nothing gets compressed. ONE SEARCH BOX OVER EVERYTHING! - Results show up as you type, ranked by how well they match. - Partial words are fine. Type "hot pass" and you'll get "Hotel Password". - Screenshots and photos get read on your device, so that photo of a hotel Wi-Fi card turns up when you type "wifi". - PDFs and documents get read the same way, so you can find a file by a phrase buried on page four. FIND IT WITHOUT OPENING THE APP! - Everything you save goes into system search. Swipe down on your Home Screen, type what you remember, and it's right there. ORGANIZED WITHOUT THE FILING! - The moment something arrives, TopDrawer gives it a title and a few tags using on-device intelligence, so you don't have to name anything. On devices that don't support on-device models, items get a title and tags from their own content instead. - No folders to build, no tree to keep tidy. Search is the filing system. REUSE IN ONE TAP! - Tap an item and it's copied. Paste it wherever you were headed. - Whatever you used last comes back to the top. YOUR STUFF STAYS YOURS BECAUSE WE TOO BELIEVE PRIVACY IS FUNDAMENTAL HUMAN RIGHT. - Everything you save lives on your device, in TopDrawer's own private storage, protected by the same encryption iOS uses for the rest of your data. - There is no TopDrawer server, so your snippets, screenshots, files and documents are never uploaded anywhere. Not to us, not to anyone else. - Reading text out of your screenshots and PDFs happens on your device. So does the titling and tagging. Nothing is sent off to be processed. - No account, no sign-in, no cloud sync, no ads, no third-party trackers, and no analytics on what you save. - We don't track you across apps or websites, and you'll never see a tracking prompt from us. - We have no copy of your content, which means there is nothing for us to sell, share, or hand over. That isn't a policy we could change later. It's how the app is built. - The only thing that ever leaves your device is your purchase, and that runs through the App Store the same way every other in-app purchase does. - Works with no connection at all. Turn off Wi-Fi and cellular and TopDrawer still does everything except buy Pro. - Leverages on-device Apple foundation models for AI compute & efficiency and nothing you save ever leaves your device. FREE, AND ULTRA WHEN YOU NEED IT! - Free: keep up to 30 items, with every feature working. - Lifetime Pro: one purchase, unlimited items, for good. Not a subscription. Restore it on any device signed in to the same Apple Account. ALL PLANS FOR ALL THE NEEDS! - TopDrawer Ultra Monthly starts at just $ 4.99 - TopDrawer Ultra Yearly starts at just $ 24.99 - TopDrawer Ultra Lifetime starts at just $ 59.99 I really want our app to be more accessible and so we have a plan for almost everyone! Plus you can always use the app first and get the feel as it comes with 30 free storage items slots for free! MADE FOR PEOPLE WHO MOVE FAST! Built for iPhone on iOS 26 or 27 by Jaimin, one of the person behind ZestMavericks studio. If you live in the share sheet and in system search, TopDrawer works the way you already do.

Verdict
The clearest difference is in-app purchases: Onetime. at none against TopDrawer's 3. Onetime. also leads on iOS requirement (13.0 vs 26.0). TopDrawer's advantage is update cadence (weekly vs every 11 months). On price, ads and device support there is nothing between them.
