Startline

"I know exactly what to do. I just can't start." That gap - between knowing and starting - is where task paralysis lives. Planners organize the day. Timers count it down. Neither one closes the gap. Startline was built for that exact moment, and for the way ADHD brains actually work. It has one job: get a person from frozen to a running focus session on ONE thing, with a two-minute first step, in under a minute. Dump the noise in your head. Pick one thing. Get a tiny, physical first step. Start. Any start counts as a win. TIME YOU CAN FEEL A solid block of time shrinks on the screen and on the Dynamic Island, so a session stops being an abstract number and becomes something you can watch. Over weeks, Startline learns your real time multipliers per kind of task - the emails guessed at ten minutes that always take twenty-four - and shows them back to you, kindly. SURVIVE INTERRUPTIONS Pulled away mid-task? One tap leaves a breadcrumb. When you come back, Startline walks you to the exact step you were on, then counts you in, 3-2-1. NO SHAME, EVER No overdue piles. No streaks to break. No red badges. A Momentum meter grows with any start and fades gently - it never resets to zero. Designed for ADHD brains. Startline is a productivity tool, not medical advice or treatment. FREE, FOREVER Unlimited brain dumps and focus sessions, Pick One, 10 ramps, one breadcrumb at a time, 14 days of time calibration, and Momentum. The whole core loop works offline on day one. STARTLINE PLUS - All 50 ramps plus custom ramps you save yourself (the free tier has 10). - Your full time-calibration history and personal multipliers (free keeps 14 days). - Unlimited breadcrumbs across every task (free keeps one at a time). - Procedural brown, pink, and white noise plus rain, generated on device. - Widgets, the Action Button, and Start my One Thing. - Optional gentle time pings during a session. - A near-monochrome, motion-free theme. - Search your Someday drawer. Plus is one purchase: Lifetime 34.99 USD (pay once, own it), Annual 12.99 USD with a 14-day free trial, or Monthly 2.99 USD. Subscriptions renew automatically unless turned off at least 24 hours before the period ends. Payment is charged to your Apple Account. Any unused part of a free trial is forfeited when you buy. Lifetime is a one-time purchase and does not renew. Manage or cancel anytime in your App Store account settings. Startline works fully offline and is designed exclusively for iPhone.

Verdict

The call

The clearest difference is ads: Startline at none against Geek Math's shown. Geek Math's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 18.2). On price and in-app purchases there is nothing between them.
