“Unique sounds like syrup with dirt kicked into it. If Bootsy Collins, Roger Troutman and Daft Punk would have met up in Studio 54 to create a soft-synth, for sure something like Unique would have come out of it…” Sound & Recording Mag Unique was made for fun and vibes: Analogue sound, intense modulation and a killer set of features, delivering an amazing sonic spectrum that’s full of character: Classy sounds, powerful, warm… sometimes gritty. Each of the 2 oscillators offers a selection of 5 waveforms: sawtooth and pulse waves are here, along with noise, triple saw and triple FM waves. There's also an additional sub-oscillator strapped into the master section for added oomph. The internal controllers will bring in the dynamics: an LFO and an envelope, there's a recordable XY field & a sequencer. Use these to modulate any knob – a simple long tap will do. The sound springs to life when it hits the filter section. Needless to say, analogue high-pass, low-pass and band-pass varieties are in place, along with a comb filter. Standards aside, the actual intention behind this project, the Vowel Filter, also became its outstanding feature: string together two or four vowel formants and play them back in a multitude of ways. Once you’ve built your sound, there’s tons of sound polish in two chained multi-effect units. Features • Sawtooth, Triple Saw, Pulse, Triple FM, Noise with tonal Filter, Sub Sine • 5 Filters with 5 Modulators each • Duophone Arpeggiator • Vowel Filter • Two Effect Sections • Ableton Link Kit • MIDI Learn & Host Automation • 300 groovy presets by various artists

Verdict
The clearest difference is price: Unique for iPad at Free against iDousyn's $5.99. Unique for iPad also leads on review sentiment (63% vs 34%) and iOS requirement (17.6 vs 26.0). iDousyn's advantage is rating (4.2 vs 3.4) and ratings volume (161 vs 18). On update cadence, ads, in-app purchases and monetization model 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
Unique for iPad is free to download; iDousyn costs $5.99 up front. iDousyn sells 1 one-off in-app purchase and Unique for iPad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
iDousyn holds the better App Store score, 4.2 against 3.4. That said, the two scores are not equally well evidenced: iDousyn has 161 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 34% of iDousyn's written reviews are positive against 63% of Unique for iPad's, so the app with the better star average is not the one people write more warmly about.
iDousyn ships an update every 2 months, Unique for iPad every 5 weeks. Both last shipped on October 29, 2026.
