# Rithmatic vs DroneSynth

The clearest difference is rating: DroneSynth at 5.0 against Rithmatic's 4.6. Rithmatic's advantage is monetization model (free vs free with in-app purchases) and ratings volume (9 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Rithmatic sells 4 one-off in-app purchases and DroneSynth sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DroneSynth holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Rithmatic has 9 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 days. Both last shipped on October 31, 2026.
