A cross-platform deep dive into StroboPro’s cloud sync feature; published on blog.strobopro.se
StroboPro syncs your custom instruments, piano profiles, and settings across iOS, Android, and the web, and lets you share any tuning with a URL. StroboPro is available on all three platforms at strobopro.se.
If you have spent time building custom tunings for alternate guitar voicings, pedal steel configurations, or piano stretch curves, losing that work because you switched phones or opened a browser is a real problem. StroboPro’s cloud sync is built to prevent exactly that.
The Problem: Apps Are Silos
This is 2026. Your notes sync across devices. Your passwords sync. Your photos sync. Yet your tuner settings, the carefully crafted alternate tuning you built for that Nick Drake song, the piano stretch curve you measured for your specific Kawai grand, those evaporate the moment you switch devices.
Built-In Tuning Editor: Build Any Tuning, Any Instrument
Before you can sync or share a tuning, you need to create it. First, most tuner apps either do not let you create custom tunings at all, or limit you to a handful of presets. By contrast, StroboPro includes a tuning editor built into the app.
What you can do:
- Add and remove notes: define any number of strings with any pitch.
- Set exact frequencies: specify pitch by frequency (Hz), note name with octave (e.g., C#3), or cents offset from equal temperament.
- Name your instrument: organize with instrument name, type, and tuning name in a three-level hierarchy.
- Use AI to generate tunings: describe what you want in plain language (“Open G tuning for slide guitar, low to high”) and StroboPro builds it for you.
- Duplicate and modify: copy any built-in or custom tuning as a starting point.
The editor works identically on iOS, Android, and web. For example, create a tuning on your phone during practice, refine it on your laptop at home, and use it on your tablet at a gig: the same tuning, the same interface, everywhere.
StroboPro ships with built-in tunings for guitar, bass, pedal steel, violin, mandolin, banjo, and more. The tuning editor is for when those presets are not enough, when you need something specific to your instrument, your genre, or your ears.
How Cloud Sync Works
Sign in to StroboPro with Google, Apple, or email. From then on, everything syncs automatically.
What syncs across all your devices:
- Custom instruments and tunings: anything you created or modified in the tuning editor.
- Piano profiles: inharmonicity measurements and stretch curves built with the Piano Tuning Assistant.
What syncs per device:
- Reference frequency: A4 = 440 Hz, 442 Hz, or whatever you prefer.
- Transposition settings.
- Last selected instrument and tuning.
The reason for the split: your phone has a different microphone than your laptop. Audio settings that work on one device may need different values on another. Your instrument library travels everywhere; device-specific settings stay optimized per device.
How it works in practice: sign in on a new device, and StroboPro merges your cloud library with anything already stored locally, automatically detecting duplicates. There is no export/import workflow and no “sync now” button. Save an instrument on your phone, and it lands on your tablet and laptop within seconds.
Offline Fallback
Not signed in? In that case, StroboPro still saves your instruments locally. Sign in later, and those local instruments merge with your cloud library. You never lose work, even if you start using the app before creating an account.
Share Any Tuning With a URL
StroboPro lets you share any custom tuning by sending a URL. The recipient does not need an account and does not need to install anything; they just tap the link, and the tuning opens ready to use.
On mobile, tapping a shared tuning link opens StroboPro directly. On web, it opens the tuning in the browser at strobopro.se. The recipient can tune immediately or save the tuning to their own library.
Real-World Use Cases
Music teachers: send a tuning link to your student before their lesson. They tap it, and their phone is ready with the exact tuning you want them to use. No confusion about which notes to tune to.
Band members: share your Drop C# tuning with your bandmates in a group chat. One tap, everyone is in tune. No more “which C# is it, the one on the 4th fret or the 2nd?”
Online communities: post a tuning link in a forum or Reddit thread for an alternate tuning you discovered. Anyone can try it instantly, with no app install required.
Luthiers and techs: send a client a link to the exact intonation tuning you used for their guitar, so they can check intonation at home.
Privacy-First Cloud Sync
Cloud sync is only valuable if you trust the platform handling your data. StroboPro’s approach:
- Delete anytime: StroboPro includes a “Delete Data and Log Out” option that removes all your data from the cloud.
- Your data is yours: StroboPro does not sell your tuning data.
- No ads: StroboPro is ad-free. Your tuning data is not the product.
- Hosted in Europe: subject to EU data protection regulations (GDPR).
By contrast, free tuner apps supported by advertising treat your usage data as their revenue stream. StroboPro’s business model is a premium mobile app, not data harvesting.
FAQ
Does cloud sync work on the free web version?
Yes, sign in on strobopro.se and your custom instruments sync to and from the web. The web version is a complete tuner with the same sync capabilities as the mobile apps.
Do I need an account to use StroboPro?
No, StroboPro works without signing in, and your instruments are saved locally. However, signing in enables cloud sync across devices and AI tuning features.
Can I share a tuning with someone who doesn’t have StroboPro installed?
Yes, tuning links open in the web browser at strobopro.se. The recipient gets a fully working tuner with your tuning loaded, with no app installation required. If they have the mobile app installed, the link opens directly in the app.
What happens to my tunings if I uninstall the app?
If you were signed in, your instruments and piano profiles are safely stored in the cloud. Reinstall, sign in, and everything restores automatically. If you were not signed in, local data is lost when the app is uninstalled, another reason to sign in.
Does StroboPro share my data with third parties?
No, your tuning data is not shared with, sold to, or accessible by any third party. You can delete all cloud data at any time from within the app.
Can I sync between iOS and Android?
Yes, StroboPro runs on iOS, Android, and the web with the same cloud backend. Your custom instruments and piano profiles sync across all platforms. Sign in with the same account on any device.
How do I create a custom tuning?
Open the tuning editor in StroboPro (any platform), name your instrument, add notes by pitch or frequency, and save. Or take an exiting tuning, modify it, and use the “Save As” button. The tuning is immediately available on all your devices and can be shared via URL. You can also use AI generation to describe a tuning in plain language (“Open D tuning for resonator guitar”) and let StroboPro build it.
