Open CSV opens any CSV file on your iPhone and shows it as a clean, scrollable table. No subscription, no ads, no account, and nothing ever leaves your device. Built for the moment someone sends you a CSV and your phone has nowhere good to open it. Features - Open CSV files from Files, Mail, or any app's share sheet - Frozen header row and first column stay put as you scroll wide tables - Tap any row to see every field laid out clearly - Sort by any column, ascending or descending - Filter rows with a quick search - Share the original file - Handles messy real-world files: quoted fields, embedded commas and line breaks, mixed encodings, and odd delimiters, without crashing Free and paid View the first 50 rows of any file for free. A single $2.99 purchase unlocks unlimited rows, forever. No subscription. What it does not do No editing, no cloud, no accounts, no analytics, no ads. It is a viewer, on purpose. Privacy Open CSV works fully offline. Your files are never uploaded, tracked, or shared. Data Not Collected. Built by Infamous Endeavors.
BrainStorm
Read full descriptionHide full description
One prompt in, six strategies out, plus a blunt critic to stress-test the plan. Free twice a day, and there is not one ad in it. Your ideas deserve the whole screen. Describe what you are working on, a business, a personal goal, or a creative project, and six specialized AI agents each pitch a distinct, actionable idea, rated for priority, effort, and impact. Then an AI critic stress-tests the whole concept: fatal flaws, key risks, false assumptions, and what has to be true for it to work. DIG INTO EVERY IDEA Get Plan: a phased execution plan for any idea, from its assigned agent Compare: put two ideas head to head Devil's Advocate: argue against an idea before you commit to it Print your full results free BRAIN FARM Every storm is planted in your Brain Farm, a living library of sessions that grow through versions as you add new thoughts and re-storm. Export any session, or your whole farm, to PDF, Word, or Markdown. AI CHAT ON EVERY IDEA Open a focused chat with an AI strategist about any single idea. Pressure-test it, refine it, and plan it without re-explaining your context. An account is required so your brainstorm sessions stay attached to you. Free accounts include 2 brainstorm sessions per day. Availability of some features depends on your account. Ideas are AI-generated starting points, not a substitute for professional business, legal, or financial advice. SUBSCRIPTION DETAILS BrainStorm Pro+AI is an optional auto-renewable subscription, $19.99 per year, starting with a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period.

Verdict
The clearest difference is in-app purchases: BrainStorm at none against Open CSV's 1. BrainStorm also leads on iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.
