Ein Hersteller bietet nächstens ein Splitflap Board (Fallblatt-Anzeigesystem) an. Um die Funktion bereits zu simulieren wurde diese App entwickelt. Die App simuliert die reale Splitflap Funktion. Alle 132 Fallblätter werden einzeln angesteuert und geblättert bis das richtige Fallblatt ansteht. Für jedes zu wechselnde Fallblatt wird ein eigener Thread erzeugt. Dadurch wird eine realistische Anzeige erreicht. Ziel dieser App ist auch eine zukünftige Ansteuerung des realen Splitflat Board. ----------------------------------------------------------------------- A manufacturer will soon offer a split flap board. This app was developed to simulate the function. The app simulates the real split flap function. All 132 flap’s are individually controlled and scrolled until the correct flap is set. A separate thread is created for each flap to be changed. This ensures a realistic display. The aim of this app is also to control the real split flat board in the future.

Verdict
The clearest difference is price: ACalc at Free against SplitFlap's $1.99. ACalc also leads on rating (4.3 vs 1.9) and ratings volume (82 vs 8). SplitFlap's advantage is in-app purchases (none vs 1) and ads (none vs shown). On review sentiment, device support and iOS requirement there is nothing between them.

ACalc is free to download; SplitFlap costs $1.99 up front. ACalc sells 1 one-off in-app purchase. SplitFlap asks for nothing beyond the download.
ACalc holds the better App Store score, 4.3 against 1.9. That said, the two scores are not equally well evidenced: ACalc has 82 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 20% of ACalc's written reviews are positive against 22% of SplitFlap's, so the app with the better star average is not the one people write more warmly about.
ACalc ships an update every 6 months, SplitFlap weekly. Both last shipped on October 14, 2026.
