Do you have an old iPad laying around that you want to put into use? Turn it into a beautiful split-flap display board. The kind you'd see in a classic train station. Flapboard Display turns a spare iPad into a live board for your home: personal messages that flip into view letter by letter (with that satisfying flutter sound), a flight you're tracking, today's weather, a favorite quote, or a countdown to the big day. HOW IT WORKS Flapboard is a two-app system, like a TV and its remote: • Flapboard Display (this app) runs on the iPad you set on a shelf or mount on the wall. It just displays. • Flapboard Remote (a separate download for iPhone or iPad) is where you compose messages and control everything. Sign in with the same account on both, choose which board this iPad shows, and you're done. You can then change what's on the board from your phone, from the next room or the other side of the world. BOARDS YOU CAN SHOW • Messages — notes to the family flip into view with the classic split-flap animation and sound • Flight — live departure info for a flight you're tracking: route, gate, times, delays, status • Weather — current conditions or today's forecast for your zip code • Quotes — a rotating quote of the day, or your own collection • Countdown — days remaining until a birthday, vacation, or launch day Turn on the boards you want; the display offers them as tabs like a real station board. Designed for always-on use — the screen stays awake while the board is up. SUBSCRIPTION A Flapboard subscription ($3.99/month, or $39.99/year — two months free — after a 7-day free trial) is purchased in the Flapboard Remote app and covers your whole account. This display app is the free screen for it. Terms of Use: https://flapboard.jrwymer.com/terms Privacy Policy: https://flapboard.jrwymer.com/privacy

Verdict
The clearest difference is in-app purchases: Flapboard Display at none against LETS SIGNAL's 1. Flapboard Display also leads on ads (none vs shown) and update cadence (every 10 days vs every 2 months). LETS SIGNAL's advantage is iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.
