How to Evaluate a Tajweed App: 5 Criteria That Actually Matter

Accuracy of Error Detection

The most important criterion. If the app can't reliably detect your mistakes, everything else is cosmetic.

What to test: Deliberately mispronounce a letter you know well (e.g., say ز instead of ذ in الَّذِينَ). Does the app catch it? Does it identify the specific letter, or just flag the whole word?

• Detects individual letter mispronunciation (not just word-level)
• Distinguishes between similar-sounding letters (ح vs هـ, ص vs س, ض vs د)
• Doesn't give false positives on correct recitation
• Catches errors consistently across multiple attempts

• Gives high scores regardless of quality (score inflation)
• Only detects the most obvious errors (e.g., wrong word) but misses subtle pronunciation issues
• Inconsistent: catches an error once, misses it the next time

Tajweed Rule Coverage

Tajweed has approximately 20-25 distinct rules. Most apps only check for a handful. The more rules an app evaluates, the more comprehensive your feedback.

The core rules every serious app should cover:

• Makharij (articulation points) — where each letter is produced
• Ghunnah (nasalisation) — including levels: Akmal, Kamil, Naqis, Anqas
• Qalqalah (echoing) — Kubra, Wusta, Sughra distinctions
• Madd (elongation) — Natural (2 counts), Permissible (2-4-6), Obligatory, Necessary
• Ikhfa, Iqlab, Idgham — noon sakinah and tanween rules
• Tafkheem/Tarqeeq — heavy and light letter distinction
• Shaddah — proper emphasis on doubled consonants
• Hamzat al-Wasl — connecting hamza rules
• Laam Shamsiyyah/Qamariyyah — assimilating vs non-assimilating laam

• Claims to "check tajweed" but only evaluates makharij (articulation)
• Doesn't distinguish between levels of ghunnah or qalqalah
• No timing analysis (madd counts)

Ask the app maker: How many tajweed rules does your system evaluate? If they can't give you a specific number and list, the analysis is probably shallow.

Scoring Methodology

A score of "75/100" means nothing if you don't know how it was calculated. Transparent scoring builds trust and helps you understand exactly where to focus.

• Shows a breakdown by category (e.g., makharij 25/30, ghunnah 12/15)
• Scores deduct for specific, identified errors — not arbitrary vibes
• A bad recitation produces a genuinely low score (not 60+ regardless)
• A perfect recitation can actually achieve 95-100
• Score range covers the full 0-100 spectrum meaningfully

• Every recitation scores between 60-80 regardless of quality (compressed range)
• No score breakdown — just a single number
• Score seems to correlate with audio length rather than accuracy

The test: Recite the same verse three times — once carefully, once normally, once deliberately sloppy. If the scores are within 10 points of each other, the scoring methodology is unreliable.

Hifz (Memorisation) Support

This is where most tajweed apps fall short. Tajweed and hifz are different skills that require different feedback — but most apps treat them as one.

The core problem: If you're testing your memorisation and you forget a word, that's a memory error — not a pronunciation error. An app that scores both on the same scale gives you misleading feedback.

• Separate scoring for tajweed and memorisation
• Detects omitted words (not just mispronounced ones)
• Detects word substitutions (said the wrong word)
• Tracks memory accuracy as a percentage
• Shows which specific words were missed, not just a score

• No distinction between tajweed and hifz modes
• Gives a tajweed score on a memorisation drill (penalises memory slips as pronunciation errors)
• Can't detect omitted words — only checks what you said, not what you didn't say

Why this matters: A hifz student who recites 90% of a verse perfectly but forgets one word should see "90% memory accuracy, 1 word omitted" — not "65/100 tajweed score." The feedback must match the skill being tested.

Coaching Depth

Knowing you made a mistake is only useful if the app tells you how to fix it. The best apps provide physical, actionable instructions — not just "try again."

• Mouth shape instructions (e.g., "Round your lips" or "Open jaw wider")
• Tongue position guidance (e.g., "Tip touches upper incisors")
• Airflow description (e.g., "Explosive burst" or "Continuous warm air")
• Timing instructions for duration-based rules (e.g., "Hold for 2 counts")
• Specific practice drills, not generic advice
• Rule explanation — name of the tajweed rule and why it applies

• "You made a mistake on this word" with no coaching on how to fix it
• Generic tips like "Practice more" or "Listen to a reciter"
• No physical articulation guidance (mouth, tongue, airflow)

The gold standard: For every mistake, you should know (1) what went wrong, (2) what the correct articulation is, (3) exactly how to position your mouth and tongue, and (4) a focused drill to practice. Anything less and you're getting feedback without instruction.
