TL;DR
A duet singing app is built for recording and sharing with a partner, not automatically diagnosing why your voice is unstable. Smule is approximately $44.99/year on the web or $7.99–$9.99/month; free users can join the second voice of an existing recording but cannot make solo recordings or lead a duet. StarMaker is free, with VIP at approximately $1.99/week or $4.99/month, Pro at approximately $7.99/week, $14.99/month, or $59.99/year, plus a separate coin economy. WeSing has free basic access; reviewed Taiwan snapshots showed $1.99/week, $3.99/month, and $10.99/quarter, while another regional Monthly Pass showed $5.99/month. Singa offers limited free access, a 30-day trial, and $9.99/month or $89.99/year. Yokee is a free karaoke app with a 7-day trial and no stable universal public price. KaraFun offers website Premium at $9.99/month and Pro at $49.99/month, with free sampling. Voloco has a free tier and All Access at $11.99/month or $59.99/year, with up to 8 tracks and a primary focus on recording and effects. Bloom Vocal is our product: it does not match duet partners or provide a karaoke catalog, but analyzes breath support, pitch accuracy, register transitions, rhythmic stability, and expression in an individual take.
A duet singing app is a collaboration tool for recording and sharing one song with a partner, while a vocal-training app is meant to explain and improve your individual technique. Those are adjacent needs, but they are not the same job. This roundup focuses on social and partner duet singing — finding someone to sing with, joining a part, coordinating a recording, or making a party session work — rather than harmony-part training.
Safety note: Do not push volume to compete with a partner or chase a higher score. Stop if you feel pain, sudden hoarseness, or breathing difficulty; if a voice change persists, seek advice from a qualified medical professional. When a phrase becomes uncomfortable around the passaggio, reset at an easier pitch and lower intensity instead of forcing it.
Karaoke collaboration and technique diagnosis are different jobs
Duets add coordination problems: joining an earlier recording, entering together, monitoring a partner, and keeping one voice from covering the other. Social and party duets need different app features.
Why a duet score is not a vocal diagnosis
If the question is “How do I find a partner for this song?”, a karaoke collaboration app is the right starting point. If the question is “Why does my pitch drop in the chorus?”, a social score is not a complete answer. Pitch guides, correction effects, and performance grades describe one take; they do not automatically explain breath support, vocal-fold contact, chest-to-head register coordination, or a passaggio break.
What to inspect in an individual take
After the collaboration, review pitch accuracy, breath support, register transitions, rhythmic stability, and expression in an individual recording with effects reduced. Semi-occluded vocal-tract work is a research-backed practice area, but no app score is a medical diagnosis.

What each app is actually best at
Social partner discovery: Smule, StarMaker, and WeSing
Smule is the clearest asynchronous fit; its free users can join a second voice but cannot record solo or lead a duet. StarMaker adds community, live participation, and coins. WeSing offers free basics with regional variation. See our Smule review.
Shared-room karaoke: Singa and KaraFun
Singa and KaraFun fit home and party sessions where catalogs, queues, and playback controls matter more than a social feed. Singa has limited free access and a 30-day trial; KaraFun has website Premium and Pro plus free sampling.
Casual sharing and production: Yokee and Voloco
Yokee offers a free flow and 7-day trial, but no stable universal price. Voloco is production-oriented, with a free tier, effects, pitch correction, and up to 8 tracks; polish is not technique feedback.
How to choose and use a duet app in 4 steps
Step 1: Define the duet goal
Choose one purpose: online partner, friend, party, layered audio, or technique review. For harmony-part training, use our karaoke duet harmony guide.
Checkpoint: Write down one priority: discovery, shared-room karaoke, production, or diagnosis.
Common mistake: Assuming the largest catalog supports your partner workflow.
Step 2: Check free access and regional pricing
Find the exact song. Check whether the second part is free and whether you can open a duet or only join one; keep trials, catalog limits, and subscriptions separate.
Checkpoint: Note the song, part access, save/share behavior, currency, trial, and renewal.
Common mistake: Treating regional prices or a 7-day or 30-day trial as universal free access.
Step 3: Record one short duet section
Start with one chorus section. Agree on a breath cue and check entry, balance, and comfort. If the passaggio feels uncomfortable, change the key.
Checkpoint: Check breath timing, entry, partner monitoring, pitch stability, and comfort.
Common mistake: Increasing volume and effort to chase a score.
Step 4: Separate collaboration from diagnosis
Read the score and effects as performance information. For an unstable phrase, make an individual take with effects reduced and review pitch, breath support, register, rhythm, or expression. See our best vocal apps comparison.
Checkpoint: Keep two notes: “Did we coordinate?” and “What does my individual voice need next?”
Common mistake: Treating an auto-corrected take as proof of improved uncorrected coordination.
Decision guide by situation
| Situation | Start with | Decision rule and useful complement |
|---|---|---|
| You want an asynchronous social partner | Smule | Check second-voice access and the free lead restriction |
| You want free community participation | StarMaker or WeSing | Test the free catalog, coins, regional passes, and locked songs |
| You and a friend share a room or host a party | Singa or KaraFun | Compare catalog, queue, key/tempo tools, and playback |
| You want casual free recording and sharing | Yokee | Test the exact song during the 7-day trial; assume no universal price |
| You want a layered duet cover | Voloco | Use up to 8 tracks, but separate polish from technique feedback |
| You want to understand a weak phrase afterward | Bloom Vocal (our product) | Collaborate elsewhere, then review the individual take across five dimensions |
Using Bloom Vocal after a duet
Bloom Vocal is our product, not an automatic first-place winner in a social-duet roundup. It does not match partners, host a karaoke catalog, record a two-person duet, or offer multi-track production. Smule, StarMaker, and WeSing fit social partner singing; Singa and KaraFun fit shared-room karaoke; Voloco fits layered recording.
Bloom Vocal becomes relevant after the collaboration. Bring in an individual take and separate “Did we coordinate?” from “What is my voice doing?” It analyzes breath support, pitch accuracy, register transitions, rhythmic stability, and expression. That makes it a complementary personal-practice layer, not a replacement for the apps that make the duet happen.

Step 1: Define the duet goal
Choose one priority for this session: finding an online partner, singing with a friend, hosting a party, layering a recording, or reviewing your own technique.

Step 2: Check free access and regional pricing
Confirm that your song and the second vocal part are available, then inspect the app or website checkout for local pricing, trial terms, and renewal conditions.

Step 3: Record one short duet section
Start with one chorus section rather than a full song. Check the shared breath cue, entry timing, partner monitoring, and whether either singer is pushing for volume.

Step 4: Separate collaboration from diagnosis
Read the duet score and effects as collaboration feedback. If a phrase feels unstable, record an individual dry take and review its pitch, breath, register, rhythm, and expression separately.
