Metronome & Time Trainer by Ju

Analysis by Appwesome

I judge a metronome by whether it helps me play more steadily, not simply by how many controls it puts on screen. Metronome & Time Trainer by Ju has a useful idea at its center: pair a straightforward beat with practice that makes me keep time when the clicks disappear. That gives it a clearer purpose than a basic ticking app, though I would not call every detail a reason to switch from a metronome I already like. It is a paid music and audio app from JustinGuitar, and its strongest appeal is to players who want to work on their internal pulse rather than just follow a beat.

Mastering the Beat

First off, let's talk about the core feature: the metronome itself. It's designed with precision in mind. You can set it to any tempo you need, whether you’re tapping out a slow ballad or jamming to a fast-paced rock anthem. The interface is clean and intuitive, so you won’t find yourself lost in settings. Just open the app, set your tempo, and you’re ready to go.

One of the coolest parts? You can customize the time signatures. Whether you’re working in a standard 4/4 or something more exotic like 7/8, Metronome & Time Trainer by Ju has got your back. It’s like having a personalized rhythm coach in your pocket.

Time Training Magic

Now, onto the Time Trainer aspect. This feature is a game-changer for musicians who want to sharpen their timing skills. It offers exercises that challenge your ability to keep time without being overly reliant on the metronome clicks. The app randomly mutes the sound during your practice, which forces you to maintain the tempo on your own. It’s like having a personal trainer who knows just when to step back and let you shine.

This function is perfect for both beginners who are just getting a feel for rhythm and seasoned players looking to refine their skills. It's a subtle yet effective way to improve your internal clock without even realizing it.

Versatility at its Best

Besides the standard metronome and time training, the app offers a variety of other features that make it versatile for different users. For instance, there’s a tempo tap function where you can tap along to a song to find its tempo. This is particularly handy when you’re trying to match the pace of a piece you’re learning by ear.

Another neat feature is the ability to save presets. If you have a few go-to tempos for different songs or exercises, you can save them for quick access. It’s all about making your practice sessions as hassle-free as possible.

Make the silent bars work for you

The muted-click exercise is the part I would build a routine around, rather than treating it as a novelty. Start with a passage you can already play comfortably, use the beat to settle into it, and then pay attention to where you land when the sound drops out. If you consistently rush into the next audible beat, the gap is telling you something useful: your pulse may be attached to the click instead of carried through the phrase. That distinction is more helpful than simply turning up the tempo and hoping for cleaner playing.

I would also resist making the exercise difficult too quickly. A short silent stretch at a manageable pace can expose shaky timing more clearly than a fast setting that makes the whole passage feel chaotic. Once the rhythm feels dependable, raise the challenge gradually. The goal is not to prove that you can survive a mute; it is to hear whether your own playing stays even when the external reference returns.

A practice routine that fits real life

Imagine you have a few minutes before leaving for work and want to run through a guitar chord change that keeps catching you out. I would tap the song or passage to get a starting tempo, save that setting if it is one I will revisit, and practise the change with the regular beat first. Then I would use the time-training exercise to check whether I can keep the same pulse through a quieter stretch. That sequence turns a quick session into more than repetition: I get a reference, work on the movement, and test whether the rhythm holds without constant prompting.

For a longer practice session, presets can make switching between a warm-up and a song less fiddly. I would label the mental purpose of each saved tempo, rather than relying on memory alone: one might be for a slow chord transition, another for a comfortable run-through. The practical benefit is not that a preset improves technique by itself, but that it removes a small setup decision when I would rather spend the time playing.

Tap tempo is especially useful when learning by ear, but I would treat its result as a starting point, not a verdict. A performance can breathe, and a song’s pulse may feel different depending on whether I tap the main beat or a subdivision. I would tap through several measures and compare the result against the way the phrase actually sits under my hands. If the click feels wrong despite a plausible tempo, the issue may be the subdivision or the feel of the passage rather than the number I tapped.

Where it beats a basic metronome—and where it does not

Compared with the usual free or built-in metronome, the meaningful distinction here is the training angle. A plain click is often enough when I need a steady reference while tuning a performance or drilling a difficult bar. This app has more value when I want the reference to withdraw so I can check my own steadiness. If I only need a simple pulse and never use the silent practice, a familiar basic metronome may be quicker and easier to justify.

It also differs from practicing with a song or backing track. Playing along can make a session more enjoyable and help with musical feel, but the arrangement may cover up small timing slips. A clear metronome beat is less forgiving; the gaps in the Time Trainer make that test tougher still. I would use music for phrasing and enjoyment, then use this app for focused timing work, rather than expecting either approach to replace the other.

There is a trade-off in that focus. A metronome can encourage a stiff performance if I treat every note as a mechanical target. For expressive music, I would use it to establish a stable pulse during practice, then turn it off and listen for phrasing, dynamics, and natural movement. The app helps me examine timing; it cannot decide what the music should feel like.

Who will get the most from it

I think it is best suited to learners who already practise with a beat but want to become less dependent on one. Guitarists working through chord changes, scales, or a tricky passage can use the regular click for control and the muted sections as a reality check. Players exploring less familiar time signatures may also appreciate being able to set a meter that matches the exercise instead of forcing everything into a simple four-beat pattern.

Teachers and self-directed learners can use it in short, repeatable drills: choose one passage, settle on a comfortable tempo, and listen for whether the return of the beat lines up with the player’s own sense of time. The same idea can help with dance practice or another rhythm-based activity, although I see its clearest use in instrument practice, where a steady pulse can be applied directly to repeated musical phrases.

I would skip it if what you want is a complete music-learning course, a song library, or detailed coaching on technique. Its role is narrower: it gives you timing tools and a way to practise without leaning on every click. It is also not my first choice for someone who wants a no-cost utility and has no interest in the training exercise. Paying for a specialised tool makes more sense when that particular practice method is something you will actually return to.

Practical details and honest limits

The app is rated for Everyone, and it runs on Android 6.0 or later. It costs $1.99, so I would think of it as a small, focused purchase rather than an all-purpose music package. Its current version is 1.09. JustinGuitar is the developer, and the app has a 4.2 average from 79 ratings, with 10K+ installs. Those figures suggest it has found an audience, but they do not tell me whether its approach suits a particular player; the useful question is whether silent-beat practice matches your needs.

Because its appeal rests on timing practice, it may feel limited if you expect a broad set of lessons or a highly personalised training plan. I would not choose it as a substitute for instruction when the underlying problem is fingering, technique, or understanding a rhythm pattern. A metronome can reveal that I am drifting, but I still have to work out why. Sometimes the answer is to slow down, simplify the passage, or count aloud before playing it again.

One practical habit is to keep the exercise musical rather than turning it into a test of endurance. Use a phrase short enough to repeat accurately, count subdivisions when the beat is sparse, and stop if the silent section makes you lose the shape of the music completely. Another is to compare a metronome run with an unaccompanied run afterward. If the latter sounds tense, I would spend a little time playing freely; accuracy matters, but so does learning to carry the pulse naturally.

My recommendation

For a player who wants to move beyond following clicks, this is a purposeful alternative to a bare-bones metronome. The combination of tempo control, time signatures, tap tempo, saved presets, and practice that periodically removes the sound gives me a useful set of ways to approach rhythm. I especially like the idea of using the silent passages as feedback rather than treating them as a gimmick. The limitation is just as clear: if you will only turn on a steady beat now and then, the extra training focus may not earn its place in your routine.

Overall, I would recommend it to musicians who are willing to practise timing deliberately, especially learners who want to know whether they can hold a pulse without constant audible help. I would choose a simpler alternative for occasional beat-keeping, and a teacher or structured lesson resource for broader musical guidance. If the specific challenge is keeping time through the gaps, though, this app gives that challenge a practical place in an everyday practice session.
