Getting started
Do I need an account?
No. Humlo uses a device-based identity — open the app and start creating. Your identity persists across reinstalls on the same device. You can delete all your data at any time from Settings → Delete Account.
How do I record my voice?
On the Create tab, tap Record your voice. We ask for a 30-second sample of natural speech or singing. The clearer the recording, the better the cover — find a quiet room, hold the phone close to your mouth, and avoid background music.
Can I pick any song?
Yes. You can paste any YouTube link, or search the in-app catalog. Each cover uses a 10–30 second segment that you either pick manually or let the app auto-detect (usually the chorus).
Subscriptions & billing
What plans are available?
- Weekly — $6.99 / week. Unlimited AI voice covers + 1 Fast music video per week. Fair use applies.
- Monthly — $19.99 / month. Unlimited AI voice covers + 4 videos per month (up to 2 HD, up to 2 in 30-second length). Fair use applies.
- Annual — $49.99 / year. Unlimited AI voice covers + 2 Fast videos per rolling 30 days. Fair use applies.
“Fair use” means that under normal use you will never hit a cap. Power-user soft caps and the exact thresholds are documented at humlo.app/terms#fair-use.
How do I manage or cancel my subscription?
Subscriptions are billed and managed by Apple, not by Humlo. To change or cancel:
- Open the iOS Settings app.
- Tap your name at the top → Subscriptions.
- Select Humlo → Cancel Subscription.
Your access continues until the end of the current billing period, and will not auto-renew.
How do I get a refund?
All purchases are processed by Apple. Refund requests must be submitted to Apple at reportaproblem.apple.com. Humlo cannot issue refunds directly. If you have a billing dispute or believe you were charged in error, email support@humlo.app with your Apple order number and we will assist.
Restore purchases on a new device
Open Humlo → Settings → Restore Purchases. Sign in with the same Apple ID used for the original purchase.
Video top-ups
Top-up credits are one-time purchases that add extra music video renderings to your account on top of whatever your subscription already includes.
- +1 Fast music video — $1.99
- +1 HD music video — $2.99 (also unlocks HD on Fast-only plans)
- +3 Fast music videos — $4.99 (best value)
Expiry: credits expire 30 days after purchase if unused. Credits are non-refundable once consumed. If you buy a top-up and it doesn’t appear within a minute, tap Restore Purchases — this re-syncs with Apple.
Covers & videos
How long does a cover take?
Audio covers typically finish in 2–4 minutes. Video covers take 4–8 minutes because of animation and lip-sync rendering. You don’t need to keep the app open — we’ll show the result in your Library when it’s ready.
My cover sounds muddy or off-key
Voice-model quality depends on the voice sample you provided. Re-record in a quieter environment with clearer articulation, then try the same song again. You can have multiple voices active in Settings → Voices.
Can I download or share a cover?
Yes — on any completed cover, tap the Share button. Audio exports as MP3 with artwork, videos export as MP4 (9:16, with a short Humlo outro on free-tier exports).
Account & data
What do you store about me?
See the full breakdown in our Privacy Policy. In short: a device identifier, your voice recordings, your generated covers, and app analytics. We do not collect name, email, or phone number unless you email us for support.
How do I delete my data?
Open Humlo → Settings → Delete Account. This removes:
- Your voice model and all recorded voice samples.
- All your generated covers and videos.
- Your device identifier from our servers.
Deletion completes within 30 days. You can also email support@humlo.app from the address on file to request erasure.
Troubleshooting
The app won’t record my voice
Check Settings → Humlo → Microphone is enabled. If it was denied earlier, you’ll need to toggle it back on manually — iOS remembers the denial.
My cover is stuck in “Processing”
Processing times can spike during peak hours. If a generation is still pending after 20 minutes, pull down to refresh. If it still doesn’t resolve, email us with the generation time and the song name and we’ll investigate.
Paywall doesn’t load / shows no plans
This usually means the device has no StoreKit connectivity — toggle airplane mode off, ensure you’re signed into an Apple ID, and retry. Corporate/VPN networks sometimes block Apple’s StoreKit endpoints.
“Restore Purchases” doesn’t restore anything
Make sure the Apple ID currently signed into Settings → [Your Name] → Media & Purchases matches the Apple ID that made the original purchase.
