The Fold: Clients approve your social posts in one swipe

Hi Product Hunt 👋 I'm Valerian, and I built The Fold after years of running social media for local businesses and town halls in France. The hardest part of the job was never writing posts. It was getting clients to approve them: emails lost in inboxes, screenshots on WhatsApp, "can you change one word?" at 11 pm, and no proof of who said yes. The Fold does one thing well: • your client gets the week's posts on their phone as cards: swipe right to approve, left to ask for a change. No account, nothing to install; • a reminder goes out before the deadline, and you're told as soon as they reply; • every approval is kept with the name, time and approved version; • on Facebook and Instagram, you pick the time. Your client approves. The Fold publishes. Pricing is per client portfolio, never per reviewer, so your clients' whole team can approve for free. The interface is in French for now (our market is France), with a 14-day free trial, no credit card. I'd love your feedback, especially from agencies: what makes client approval painful for you?
