Every fiber colour-code app on the store is the same static chart: search a number, read a colour, close it. The category leader is a $2.99 lookup table whose own top review asks it to say which buffer and which ribbon to break — and it still doesn't. Fiber Master answers that as computation, not as a longer chart: it ships TIA-598-D in the binary and resolves any fiber on any cable to 1728F through binder, buffer tube (tracer bands included — the rule almost nothing in the category teaches) and position, offline, in a truck, with no account. Then it drills you on it in sixty-second arcade runs with instant +100 XP, a 2x-5x streak multiplier and immediate transitions, and it weights every question by the confusion matrix of the colours THIS technician actually misses, so reading the analysis and improving are the same loop. The rivalry the brief wanted from a global leaderboard is preserved honestly against yourself: a recorded ghost of your own fastest run plus a computed pacer line that is labelled a calculated target everywhere it appears, scored as Bench Rank - an Elo against each question's own par difficulty, so recalling that fiber 8 is Black rates below resolving fiber 1199 on a 1728F. The generator refuses to ask about the two tube/tracer collisions TIA-598-D never settled rather than grading a technician on a manufacturer's choice. Ranks run Apprentice to Fiber Master on measured accuracy and speed, and the share card says in as many words that it is a drill achievement and not a certification. Free keeps every mode, every rank and the whole reference - the standard is Googleable and paywalling it is this category's worst habit; Pro sells the computed layer. Built as a first-party funnel for Quik Fiber Pro with configurable rotation, frequency caps and fallback, and no ad network anywhere.
Terms of Service
Effective September 7, 2026 · Last updated September 14, 2026
By downloading or using Fiber Master (the "App"), provided by Africo I Feliz, you agree to these Terms. If you do not agree, do not use the App.
Who may use the App
You must be old enough to enter into these Terms where you live, or use the App with the permission and supervision of a parent or guardian who agrees to them on your behalf.
License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for your own personal, non-commercial purposes, subject to these Terms and Apple's Licensed Application End User License Agreement.
Your content and ours
You keep all rights to the content you create in the App. You give us a limited permission to store, sync, and display it back to you solely to operate the App for you; we claim no other rights to it and do not use it for advertising.
The App itself — its design, text, and software — belongs to Africo I Feliz or its licensors and is protected by intellectual-property laws. You may not copy, resell, redistribute, or build a competing product from it, except where the law expressly allows.
Acceptable use
You agree not to misuse the App, attempt to disrupt or reverse-engineer it, circumvent its purchase or security mechanisms, or use it for any unlawful purpose. You are responsible for the content you create and for keeping your account credentials secure.
Subscriptions & purchases
The App may offer optional auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours prior to the end of the period. You can manage or cancel in your Apple ID account settings. Current prices are shown in the App.
Cancelling stops future renewals; you keep access until the end of the period you have already paid for. Deleting the App or your account does not cancel a subscription — cancel it on your device in Settings → your name → Subscriptions.
If the App offers a free trial, it becomes a paid subscription at the end of the trial unless you cancel at least 24 hours before the trial ends, and any unused portion of a free trial is forfeited when you purchase a subscription.
If we change the App in a way that materially reduces what an active subscription includes, we will say so in the App or on this page before the change takes effect.
Refunds. Purchases are processed by Apple, which is the merchant of record, so refunds are handled under Apple's policies — you can request one at reportaproblem.apple.com. We cannot issue App Store refunds directly, but we are glad to help where we can.
Disclaimer of warranties
The App is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.
Limitation of liability
To the maximum extent permitted by law, Africo I Feliz will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or profits, arising from your use of the App. Nothing in these Terms limits liability that cannot be limited under applicable law.
