It features two independent keyboards with: • 4 – 72 keys (voices, steps) per octave, each with its own ring modulator • maximum polyphony equal to the number of voices; max polyphony is 144 voices • 1 – 4 octave range, covering the frequency range of about 8 – 4200 Hz • display with note number (from C), note name, frequency (in Hz), and deviation from 12-TET (in cents) • two sections per keyboard: upper for non-sustained notes, gliding, and velocity; lower for sustained notes and modulation rate • mute button to stop/start all sound • delete/panic button to erase all notes • glide button for smooth sweeps across keyboard frequency range • modulation on/off button • slider to set initial velocity and modulation levels • slider to change velocity and modulation rates for all notes on the keyboard proportionally and to show current velocity and mod rate levels • button to toggle keyboard visibility. sinusedo supports MIDI input from external sources to control each keyboard independently. Supported devices: iPad, iPhone

Verdict
The clearest difference is update cadence: sinusedo at weekly against Stria's every 5 months. sinusedo also leads on price ($3.99 vs $9.99) and review sentiment (100% vs 91%). Stria's advantage is rating (5.0 vs 4.7) and ratings volume (35 vs 7). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Stria costs $9.99 and sinusedo $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Stria holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stria has 35 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 91% of Stria's written reviews are positive against 100% of sinusedo's, so the app with the better star average is not the one people write more warmly about.
Stria ships an update every 5 months, sinusedo weekly. The most recent releases landed on August 31, 2026 and September 24, 2026 respectively.
