Prizma
Read full descriptionHide full description
You sit down to work, and forty minutes later you're deep in a feed. Prizma closes the apps that distract you while the timer runs. Set 25 minutes and social media, video and games won't open. Time's up β they open again on their own. HOW IT WORKS 1. Pick the apps that pull you away β websites too, if you like. Once, on the first screen. 2. Set the time and start the timer. 3. Work. If your hand goes for one of them, iOS shows a Prizma screen with the time it opens again. Nothing is deleted, and you're not signed out of anything. The apps stay right where they are. They just don't open until the time is up. WHAT'S FREE - Closing apps twice a day - The timer itself, as often as you like - Stats, with no limit - Tasks, with due dates and steps - Dictating a task, three times a day - The Home Screen widget WHAT PRO ADDS - Closing apps with no daily limit - Strict mode: once the countdown starts, the only way out is a crystal you've earned - A schedule by weekday and by hour, so it starts on its own - Task breakdown: a language model turns what you said into a title, a due date and steps - Apps close automatically every time you start the timer TASKS, VOICE AND CRYSTALS You can dictate a task instead of typing it: your iPhone does the listening, and the audio never leaves it. The task you pick sits above the timer ring, and every countdown you finish counts toward it. You earn a crystal by letting one strict countdown run to the end, and it pays for one emergency exit β for when you really do need your phone. Crystals can't be bought: the price of leaving is measured in countdowns you finished, not in money. ALSO IN THE APP - Time left on the Lock Screen, in a Live Activity - A widget with your task list: check things off without opening the app - Ticking seconds, if you want to hear them - Dark and light themes - Stats by week and by month - Six languages PERMISSIONS AND PRIVACY Prizma works through Apple's Screen Time (Family Controls). On first launch, iOS asks you to allow it, because no app can close another app without that permission. You can take it back in Settings whenever you want. There is no account. The apps you picked and the hours you worked stay on this iPhone. For each app you choose, Apple hands Prizma an anonymous token instead of the app's name β so even Prizma doesn't know which apps you closed. The only thing that leaves the device is the text of a task, and only if you turn task breakdown on: it's off by default and it comes with Pro. Your voice never leaves your iPhone. The details are in the privacy policy. WHAT PRIZMA DOESN'T HAVE No account, no sync between devices. No iPad or Mac version. Nothing for teams or families. It can't read anyone else's Screen Time. Start with 25 minutes.

Deliver

Most task apps assume the hard part is organizing. It isn't. The hard part is the gap between having a thought and it being safely out of your head β and then actually following through on what you decided to do about it. Deliver is built around three words: Capture. Commit. Deliver. CAPTURE β get it out of your head, instantly Speak it or type it, from wherever you are: the app, your Lock Screen, Control Center, the Action Button, Siri or Back Tap. Speak in any language, or mix two in one sentence β Deliver writes down exactly what you said, names included. COMMIT β one honest decision, made once Every capture asks a single question: what is this? An action you'll do, something someone else owes you, or a reference or an idea worth keeping. No half-sorted inbox, no deciding the same thing three times. DELIVER β real follow-through, not just a list A focused Today view for what's actually due now. An "Owed to me" list for what you're waiting on from other people. And a "Needs you" nudge the moment something you committed to is at risk of slipping. YOUR AI CHIEF OF STAFF (PRO) Ask about your day in chat or out loud and get an answer grounded in what's actually on your plate. Ask it to move the review to Thursday, defer what can wait, or mark something done β every change comes with Undo. Daily and weekly check-ins at the times you choose: a short conversation that adjusts your plan with you. TRY IT, THEN CHOOSE A PLAN Your first 5 captures are free. Then pick a plan; both start with a 14-day free trial: β’ Basic β capture, commit and follow-through: $4.99 a month or $39.99 a year. β’ Pro β everything in Basic plus the AI Chief of Staff and check-ins: $8.99 a month or $79.99 a year. Payment is charged to your Apple ID when the trial ends. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel them in your App Store account settings. PRIVATE BY DESIGN No account and no sign-in. Your captures, actions and plans live on your iPhone, with an automatic backup in your own iCloud. Voice recordings are sent only to be written out, and you can keep recognition entirely on your iPhone in Settings. No ads, no tracking. Deliver isn't trying to be everything. It's trying to make the distance between "I thought of something" and "it's safely handled" as short as possible β and then make sure you follow through.

Verdict
The clearest difference is in-app purchases: Prizma at none against Deliver's 4. Prizma also leads on update cadence (weekly vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.
