ToneAdapt is your personal tone matching engine for the electric guitar or bass guitar. Pick any song's guitar tone, enter your specific gear, and get the original gear used + tone settings, along with custom amp, guitar, and pedal settings adapted to your exact setup in seconds. We aggregate real tone and gear data from across the entire internet — forums, gear reviews, artist rig rundowns, manufacturer specs, and community knowledge — to build the most comprehensive guitar tone database available. ToneAdapt then translates those tonal characteristics into precise settings for your amp, guitar, and pedals. No more copying YouTube amp settings that sound nothing like the original — ToneAdapt accounts for the differences in EQ curves, gain staging, and frequency response across gear brands. Whether you're dialing in Hendrix on a bedroom amp, matching tones for a cover band, or exploring new sounds on your modeling rig, ToneAdapt gives you the exact settings to get there with your gear. ToneAdapt Pro requires a recurring subscription to access unlimited tone adaptations and our full gear database. With ToneAdapt Pro, you get: Unlimited Tone Adaptations: Match any famous guitar tone to your specific gear. 9,000+ Gear Database: Amps, guitars, and pedals from every major brand. Data-Driven Matching: Settings derived from real-world tone data aggregated from thousands of sources, adapted to your exact gear combination. Community Tones: Access tones shared by 250,000+ guitarists. Subscription automatically renews unless cancelled 24hrs before your renewal date in the App Store.

String Ledger is the complete management app for musicians who take their instruments and gear seriously. Whether you own two guitars or a full touring rig, String Ledger keeps everything organized, documented, and protected. CATALOG YOUR COLLECTION Add every instrument and piece of gear you own. Log brand, model, nickname, year, serial number, color, country of origin, storage location, purchase price, and current value. Attach multiple photos to each instrument, pinch to zoom in on details, and save any photo back to your library. TRACK STRINGS & MAINTENANCE Never lose track of when you last changed your strings. Set a custom change interval, log every restring with brand and gauge, and receive push notification reminders when it's time — with a one-tap reorder link for your string brand. Double-neck guitars track each neck separately. Build a complete service history for every instrument. GEAR LIST Track all your gear too — amps, pedals, cables, microphones, audio interfaces, and more, with serial numbers, values, and service history. SETLISTS & GIG LISTS Build setlists and assign a specific guitar to each song, then print a stage-ready copy with or without the guitar names. Duplicate and rename setlists to reuse them. Build a gear list for every gig, and sort or reorder your setlists and gigs any way you like. INSURANCE-READY REPORTS Generate a professional PDF of your entire collection — serial numbers, prices, values, and service history — grouped by location. Export to a CSV spreadsheet too. Essential for insurance claims, theft recovery, or estate planning. BACKUP & RESTORE Export your whole collection, including photos, to a single backup file you can save to Files or iCloud Drive — then restore it anytime or move it to another device. BENEFICIARY RECORDS Assign a personal beneficiary to each instrument — who you want it to go to, their contact information, and any notes.

Verdict

The call

The clearest difference is review sentiment: String Ledger at 80% against ToneAdapt's 34%. String Ledger also leads on iOS requirement (16.4 vs 18). ToneAdapt's advantage is ads (none vs shown) and rating (4.8 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ToneAdapt sells 15 in-app purchases, starting at $5.99 per 7 days and String Ledger sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

ToneAdapt holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: ToneAdapt has 3.2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 34% of ToneAdapt's written reviews are positive against 80% of String Ledger's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ToneAdapt ships an update every 6 days, String Ledger fortnightly. Both last shipped on October 25, 2026.
