Singing Carrots trains your voice: an AI vocal coach that adapts exercises to you, with published outcome data (beginners gained +16.5 percentage points in pitch accuracy over four weeks). If you want to enjoy songs today, Simply Sing; if you want to sing better next month, Singing Carrots. Many people use both.

Simply Sing in two paragraphs
Simply Sing — from the team behind Simply Piano — is built for people who want to sing right away. A quick vocal range check classifies your voice type (with famous singers who share your range), and then every song in the catalog can be shifted into your comfortable key with a slider. Lyrics and note bars guide you in real time, and each take ends with a pitch-and-timing score. Levels and XP keep it game-like.
What it deliberately doesn’t do is teach: there’s no instruction on breath, resonance, or registers, no explanation of why a note went wrong, and the key slider doesn’t show semitone values, so you never quite know how far a song was moved. The free trial is short before the paywall. None of that is a flaw in what it’s for — it’s a confidence and enjoyment app, and as we said in our iOS apps guide: it feels like singing, not homework. Shy beginners and kids stick with it for exactly that reason.
Singing Carrots in two paragraphs
Singing Carrots is vocal-only training built around an AI vocal coach that listens in real time and plans each session for your specific voice — keeping 91.5% of exercises inside your demonstrated comfortable range, adjusting difficulty to how you’re actually doing, and remembering your progress between sessions. Since July 2026 it also hears voice quality — airiness, ring, vibrato, loudness — not just pitch.
It’s the only app in this comparison with published outcome data: beginners gained +16.5 percentage points of pitch accuracy in four weeks, and the gains held at three months. Around the coach: the free vocal range test, pitch accuracy test, real-time pitch monitor, range-matched song search, and structured courses from beginner to intermediate.
Its limits, honestly: no licensed karaoke catalog. Simply Sing’s sing-along-to-real-songs experience is simply not what this is. And full AI coaching requires a paid membership, though the core tools are free.
What are the key differences?
• Adapting songs vs adapting training. Both apps “adapt to your voice,” but to different ends: Simply Sing adapts the song so you can enjoy it comfortably today; Singing Carrots adapts the training so your voice itself changes over time. Comfort vs growth.
• Score vs diagnosis. Simply Sing tells you how a take went (a score); Singing Carrots tells you what happened and why — sharp or flat, by how much, on which notes, trending which way over weeks.
• Evidence. Singing Carrots publishes its outcome data, methodology and limitations included; Simply Sing publishes none. Only one of the two lets you check the claim that it works.
• Who each is really for. Simply Sing: shy beginners, kids, anyone intimidated by “exercises.” Singing Carrots: anyone who wants measurable improvement — and per the data, beginners gain the most, so the audiences overlap more than the products do.
Which should you choose?
• Choose Simply Sing if: your goal is enjoying songs, building confidence, or getting a hesitant beginner (or a kid) to sing at all.
• Choose Singing Carrots if: you want your voice to measurably improve — pitch, range, consistency — with coaching that adapts to you.
• Use both if: you like the split: technique sessions with the AI coach, fun song sessions in Simply Sing. They barely compete. For the wider field, see the Top 7 AI vocal coaches compared and our best iOS singing apps guide.
FAQ
It’s genuinely good at what it targets: confidence, pitch awareness, and enjoyment, with songs adapted to your comfortable key. It doesn’t teach technique: no breath, resonance, or register instruction, and no diagnosis of why notes go wrong. Fun with real songs: yes. Structured vocal development: that’s not its job.
Both are beginner-first, differently. Simply Sing is the gentler entry — singing real songs immediately, no exercises. Singing Carrots gives beginners adaptive coaching, and its published data shows beginners improving most (+16.5pp in four weeks). A fair rule: Simply Sing to start enjoying singing; Singing Carrots to start improving at it.
No, and it doesn’t claim to. It provides real-time note guidance and a pitch/timing score, but no instruction on breath support, resonance, or registers, and no per-note diagnostics. For technique, you’d pair it with a training tool or a teacher.
Yes, and it’s a natural pairing because they barely overlap: train with the Singing Carrots AI coach a few sessions a week, and use Simply Sing when you want to enjoy songs in a comfortable key. Skill from one shows up in the other.
