Inner Clock
Read full descriptionHide full description
Inner Clock asks you to stop a hidden timer at 2, 3, 5, 7 and 10 seconds. The screen shows no running numbers: you press START, count in your head, and press STOP when you think the target has passed. After each of the five rounds you see the target, the time you actually stopped at and the error. When all five are done, your average error places you in one of six types, from Human Atomic Clock to Free Spirit, along with your best and weakest round. An optional card on the result screen shows whether you tend to stop early or late and whether you were closer on the short targets (2 and 3 seconds) or the long ones (7 and 10 seconds). You open it by watching a short ad. You can send the result as an image together with a line of text that names your type and average error. A practice mode lets you repeat any single target as often as you like before the five rounds. Available in 10 languages: English, Korean, Japanese, Simplified and Traditional Chinese, Spanish, Portuguese, Indonesian, German and French.
Draft AI

Draft is the daily writing practice app for people who keep saying they want to be writers โ and want to actually become one. Five minutes a day. One sentence about what you're working on. A daily prompt seeded by your own story. A streak that builds over weeks, not flashes that die in three days. โ HOW IT WORKS โ Tell Draft your one-sentence pitch. "A woman in Berlin finds a letter on the U-Bahn." "A memoir about my grandmother." Anything. Vague is fine. Every day, Draft sends you three short rings: โข Brain dump โ three pages, unfiltered, the way Cameron taught. โข Copywork โ write out a passage from a master. Plath. Hemingway. Didion. โข Guided writing โ a fresh prompt seeded by your own pitch. Twenty-five minutes total. Less if you want. โ BUILT FOR THE WRITER WHO ALMOST GAVE UP โ Most writing apps are clever. Draft is brutal in the best way. It doesn't gamify; it doesn't motivate. It shows up every morning and asks if you wrote yet. That's the entire mechanism. If you're someone who has ten unfinished documents, three abandoned Substacks, a Notion full of "story ideas" โ Draft is for you. โ WHAT'S INCLUDED โ โข 24-week structured program โข Daily personalized prompts (powered by AI, seeded by your pitch) โข Streak + progress tracking โข Copywork library: passages from Plath, Didion, Hemingway, Carver, and more โข Privacy-first: your writing stays on your device unless you explicitly back it up โ SUBSCRIPTION โ Draft is free to download with a 7-day free trial. After the trial, an auto-renewing subscription is required to continue daily access. Pricing is shown in-app before purchase. You can cancel anytime in iPhone Settings โ Apple ID โ Subscriptions.

Verdict
The clearest difference is in-app purchases: Inner Clock at none against Draft AI's 2. Draft AI's advantage is update cadence (weekly vs every 7 months) and iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
