"a looper unlike any other.. you would be damn wrong not to test it.." - Guitar Part Magazine June 2014 (biggest french guitar magazine) Loopr is the first 64 tracks loop song sequencer / multiple phrase looper with MIDI controls and sync for real time live composition. A musical instrument like no other. "Loopr is a budget-priced bargain that is well worth a punt even if only to experiment with. This is a very capable – if slightly quirky – looper app at a pocket money price." musicappblog.com November 2013 Honorable mention as finalist in the Best App Ever Awards 2013 ( http://www.bestappever.com/awards/2013/winner/musc ) Loopr is a low latency loop recorder, player and step sequencer designed for realtime phrase and song composition using your iDevice. Compose, practice, jam along, or sample audio soudscapes easily with this compact pro-oriented loopstation. It is focused on ergonomy and simplicity via one-finger but also hands-free MIDI pedalboard controls, and lets you synchronize drum machines and sequencers via its MIDI out sync. Loop sessions can be exported/imported as independent files (including tempo and time signature information), for you to share the groove or use with most desktop audio production apps (e.g. Logic Studio, Garage Band, ...). Using iTunes file sharing or email, you can easily manage your work beyond your iPhone or iPod Touch. Loopr is CoreMIDI and CoreAudio compatible and enables you to use most popular iOS compatible interfaces.

Uber Synth is a polyphonic multi-timbral frequency modulated (FM) synthesizer that runs on any iOS device. The underlying sound engine is based on the triple-oscillator cross-modulated FM synthesizer first introduced in our xMod app. Uber Synth provides five multi-timbral options: 1) Mix the sounds of any two sound patches, 2) combine patches using the sound map, 3) Generate specified as well as randomized sound palettes across the keyboard, 4) Specify a region in sound space centered on a sound and move a point by a variable randomized amount within the region each time you play a note to create an evolving mix of the center sound and the sound nearest the point. 5) Do the same as above moving the point automatically at a specified rate. Supports Audiobus.

Verdict

The call

The clearest difference is rating: Loopr Live Loop Composer at 2.3 against Uber Synth's 2.0. Loopr Live Loop Composer also leads on price ($0.99 vs $3.99) and chart position (#168 vs unranked). Uber Synth's advantage is review sentiment (40% vs 23%) and update cadence (every 3 months vs every 6 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Loopr Live Loop Composer holds the better App Store score, 2.3 against 2.0. That said, the two scores are not equally well evidenced: Loopr Live Loop Composer has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 23% of Loopr Live Loop Composer's written reviews are positive against 40% of Uber Synth's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Loopr Live Loop Composer ships an update every 6 months, Uber Synth every 3 months. The most recent releases landed on July 23, 2026 and September 21, 2026 respectively.
