Plot Spark ignites your next idea - with a single roll. Whether you're working on a novel, a short film, a tabletop RPG campaign, or just need a story for tonight: Plot Spark instantly delivers a character, a conflict, and a setting - random, unexpected, and inspiring. HOW IT WORKS Pick a kit, roll the dice - and get a complete story prompt with character, conflict, setting, and a wild twist. Sounds too simple? That's exactly the point. Prefer instant results over a dice animation? Turn the roll animation off and get straight to the prompt. ELEVEN KITS, EVERY GENRE Plot Spark ships with eleven curated kits - from neon-soaked noir and cosmic comedy to high-seas adventure, Cold War espionage, and Victorian hollow-earth expeditions. And you can create your own kits and fill every slot with your own ideas - tuned to exactly the tone you need. JOURNAL & MARKDOWN EXPORT Save every hit straight to your journal. Write notes, develop the idea, or let it simmer - your best prompts won't get lost. Export any entry, or your whole journal, as clean Markdown and keep working in your favorite writing app. FROM SPARK TO GAMEBOOK Your exported prompts are plain Markdown - the same format Story Weaver speaks, our free open-source language for writing branching gamebooks with choices, dice, and fights. Grow a rolled prompt into a full playable adventure: github.com/ComicSans/story-weaver NO SUBSCRIPTION. NO ACCOUNT. Plot Spark needs no internet connection, no login, and no subscription.

Latch blocks the apps that steal your time — and puts the unlock button somewhere you have to walk to. Pick the apps, categories and websites that pull you in, then slide the latch to lock them. To unlock, scan your key: a few-cent NFC sticker or a QR code you print at home. Keep it on the fridge, in the car or at your desk at work, and the few steps it takes to go get it are usually enough to change your mind. Latch uses Apple's Screen Time (Family Controls) to block apps on your own iPhone. Your choices stay on your iPhone. YOUR KEY, NO GADGET • Use any NTAG213, NTAG215 or NTAG216 NFC sticker — a few cents each — or a QR code you print at home (the camera scans it) • Tap the sticker with Latch closed, or scan it in the app • Stickers are locked with a password after writing, so no one can write over them. Save the password in Apple's Passwords app • Share one key with family or roommates — one sticker on the fridge for the whole house • Tell Latch where each key lives, and the lock screen tells you where to walk • One key works with all your iPhones • A steps key (Pro): walk 500 to 20,000 steps to unlock, counted with Motion & Fitness • On iPad, use a QR key. NFC stickers, the steps key and lock while driving need an iPhone LOCKS BEFORE YOU THINK TO • Built-in profiles — Work, Social and Bedtime — ready with the usual suspects • Schedules (Pro): every weekday morning, or at bedtime until you scan your key • Places: lock when you arrive at the office or the gym, and unlock when you leave (uses your location) • Lock while driving (Pro): Latch notices a drive with your location and Motion & Fitness, locks the profile you choose, and unlocks after you park • A Control Center toggle (iOS 18): tap to lock, tap again to open the scanner • Siri: "Latch my phone", or "Latch my phone with Work". Also in Shortcuts and on the Action button BUILT FOR THE DAYS YOU'D RATHER NOT • Daily limits (Pro): give an app or category a few minutes a day while you're unlocked • Commitment mode (Pro): stay locked for at least 30 minutes, or up to 8 hours • Hard lock: choose to block deleting apps, installing apps and in-app purchases while you're locked • Break glass: three times a month, open your apps for 5–15 minutes without your key; they lock again on their own • Block explicit websites with Apple's filter, per profile • Your own words on the block screen, like "Finish your work first" SEE THE TIME YOU GOT BACK • A daily locked-time goal and a streak to keep • Your last 7 days, how they compare with the week before, and a Sunday recap • How often you reached for a blocked app, and what broke your focus • Month and all-time views (Pro) • Lock Screen widgets and a Dynamic Island timer • iCloud sync between your iPhones PRIVATE BY DESIGN Latch has no accounts, no ads and no analytics. Apple's Screen Time keeps your app choices and usage on your iPhone, so we never see them. LATCH PRO — ONE-TIME PURCHASE Free includes one key, three profiles, two places and seven days of stats. Pro unlocks unlimited keys, profiles and places, schedules, daily limits, commitment mode, lock while driving, key hours, a steps key and full history. No subscription.

The clearest difference is in-app purchases: Plot Spark at none against Latch's 1. On price, ads, device support and iOS requirement there is nothing between them.
