Nerve turns screen time into a game of brains and risk. Block the apps you waste time on, then answer brainteaser questions to earn your screen time back. Harder questions unlock more time — if you have the nerve to try them. HOW IT WORKS Pick the apps you want to block. When you try to open one, Nerve challenges you with a brainteaser. Answer correctly and the app unlocks. Answer wrong and you're locked out on a cooldown. It's that simple. PICK YOUR RISK Choose from 6 difficulty tiers — Gimme, Easy, Medium, Hard, Expert, and Genius. Gimme questions earn you a few minutes. Genius questions earn you hours. But if you get it wrong, harder questions have shorter cooldowns while easier ones make you wait longer. Risk and reward, every time. DOUBLE OR NOTHING Got it right? Gamble your winnings on a harder question for double the screen time. Keep going until you cash out or lose it all. THE GAUNTLET Think you can go all the way? Start at Gimme and climb through all 6 tiers. Every correct answer adds time. One wrong answer and you stop — but you keep what you've earned. Complete all 6 for the ultimate payout. 1000 BRAINTEASER QUESTIONS Logic puzzles, lateral thinking, pattern recognition, wordplay, math tricks, spatial reasoning, number sense, sequencing, deduction, and visual puzzles. These aren't trivia — they're brainteasers designed to make you think. BRAIN SCORE Track your intellectual growth with an ELO-inspired rating system. Start at 1000 and climb through 7 ranks: Novice, Student, Scholar, Expert, Master, Grandmaster, and Genius. See your strengths and weaknesses across 10 question categories. DAILY QUESTS & ACHIEVEMENTS Three new quests every day to keep you on track. Earn streak multipliers for consecutive days. Unlock 20+ achievements as you progress. The more you play, the more screen time you earn per question.

Bio Architect
Read full descriptionHide full description
Bio Architect is an offline biography evidence studio for professionals, speakers, researchers, editors, and communications teams. Build one canonical subject dossier, trace publishable claims to source records, and shape distinct bios for each audience without sending sensitive material to a server. Start with evidence, not a fill-in template. Record employer pages, registries, publications, programs, credentials, interviews, or private document notes with provenance, visibility, dates, locators, and relevant excerpts. Turn those records into structured claims with a canonical value, editorial status, and explicit source links. Create separate variants for organization websites, conferences, media contacts, professional profiles, spoken introductions, grants, and bylines. Each draft has its own point of view, word target, selected claim map, and editor note. Review before publishing: - Find claims with missing or removed sources - Surface conflicting values for the same biography fact - Flag disputed claims and stale source reviews - Catch numbers that are not mapped to selected evidence - Review point-of-view drift and unsupported promotional language - Save immutable checkpoints and compare revisions word by word Export only what the recipient needs: - Clean biography text - Redacted editorial fact-check packet - Complete private dossier archive Bio Architect adapts its information architecture for iPhone and iPad. Everything is stored locally with SwiftData. There are no accounts, network requests, analytics, ads, tracking, third-party SDKs, or generative AI. The app never writes biography copy for you and never claims to verify a person automatically.

Verdict
The clearest difference is price: Nerve at Free against Bio Architect's $0.99. Nerve also leads on update cadence (every 4 days vs every 11 days). Bio Architect's advantage is in-app purchases (none vs 5). On ads, device support and iOS requirement there is nothing between them.
