Blue or red? This shot or the other one? Open the moment you're stuck to the crowd. WhichOne is an A/B decision app that makes you choose between two photos. You ask, the community votes. With one rule: only the people who voted see the percentages. WHY IT WORKS THIS WAY In most polls the first thing you see is the result, and then you vote along with it. Here the order is reversed: you decide first, then you see the crowd. So the number you end up with shows what people actually think. HOW IT WORKS • Upload your two photos, write your question — your poll is live in seconds • Pull the seam all the way and let go; your vote counts • After you vote, percentages, reasons and the remaining time open up • Every poll has a clock. When it ends, the result opens to everyone WHAT'S INSIDE • Reason tags: say why you picked that side in one tap, then see the breakdown • Categories: outfits, shoes and bags, hair and makeup, home decor, purchases • Share by link: anyone who opens it can vote without an account • Invite a friend: when they join, credits land for both of you • Block an account you'd rather not see; their polls leave your feed CREDITS AND PACKAGES Opening a poll costs nothing. Credits are only for showing your poll to more people. Every vote you cast earns +1 credit. • Spotlight — top of discover and search for 24 hours • Boost — shown to more people for 24 hours • Fast Decision — moved up until the poll reaches 100 votes • Targeted Votes — shown first to people who voted in that category Paid reach NEVER changes a result. It only changes how many people see it. Percentages always come from votes alone. WHICHONE PRO • Credits land in your account on every renewal • Poll durations from 24 hours up to 30 days • Poll insights: votes hour by hour, reason breakdown for both sides, live pace • Pro badge on your profile Weekly, monthly or yearly.

Verdict
The clearest difference is ads: WhichOne at none against Kalay+'s shown. Kalay+'s advantage is iOS requirement (12.0 vs 16.4). On price, in-app purchases and device support there is nothing between them.
