Turn your mobile device into a musical washboard! You can play the classic metal washboard as is, or customize it by adding instruments like horns and woodblocks in any combination. You can even add decorations like a flower, a sticker or party lights. Play along with your iPod music, or plug into an amp and join a jug band! Some reviews say the app doesn't sound like a washboard, but it does use audio samples taken from a real washboard. The samples come from a metal board played with 1" zinc washers -- this gives a sound harder than thimbles but softer than spoons -- and include a tap, scrub and wood sound. The add-on instruments also use real audio samples. Instruments include: - Small cowbell - Large cowbell - Small horn - Large horn - Tambourine - Cymbal - Small woodblock - Large woodblock - Service bell - Vibraslap - Toy chicken Decorations (no sound) include: - Toy dinosaur - Flower - Bow tie - Hula girl - Woody Guthrie sticker - Party lights If you have any MIDI equipment, you can also use Washboard as a MIDI controller. Map each instrument in the app to a note number in your sound module, then tap the board or attached instruments to send note-on commands. The MIDI commands are sent on channel 10 for easy access to most percussion modules. Before buying this app, I recommend watching the demo video at washboardapp.com to see how it works.

Verdict

The call

The clearest difference is price: TerribleSync at Free against Washboard's $1.99. TerribleSync also leads on review sentiment (83% vs 43%) and ratings volume (4 vs 1). Washboard's advantage is rating (5.0 vs 4.0) and update cadence (every 3 months vs every 35 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
