A design reference
Behavioural design
It should serve the practice. Distinguish practical support, game elements and pressure to keep using the product.
Practical takeaways
- Remove friction first; add a game element only when it serves a named, chosen task.
- Make a complete nongame route and a pressure-free return part of the design.
- Test motivation, unwanted pressure and actual task outcomes rather than assuming more engagement means more formation.
Three different design questions
Support for practice reduces barriers: a saved reading place, accessible audio, manageable session length, a cue the person chooses, or a flexible plan. It does not need a game layer.
Gamification adds game-like elements such as challenges, badges, points or streaks to a task. The question is which task they serve and whether participation remains voluntary.
Pressure and manipulation use guilt, status anxiety, hidden defaults or constrained exit to obtain activity the person would not otherwise choose. A religious message can intensify that pressure; spiritual authority must not be used as an engagement mechanism.
What the evidence can support
Self-Determination Theory’s official overview provides a lens on autonomy, competence and relatedness. It helps frame evaluation questions; it does not establish that a particular app feature improves faith.
Sailer and Homner’s educational meta-analysis examines learning, motivation and behavioural outcomes. It supports distinguishing outcomes and contexts instead of treating gamification as uniformly effective. Education findings cannot simply be relabelled spiritual-formation findings.
The decisions below are original design considerations and hypotheses. Domain-specific formation evidence requires separate review. This reference does not claim that a streak, notification, repetition schedule or AI meditation causes spiritual growth.
When the reward becomes the reason
Someone begins a reading practice because they want to know Scripture better. A visible record helps them return. Over time, they may still value that support—or find themselves opening the app mainly to protect the record. The activity can look similar in the dashboard while its meaning changes.
This is an illustrative possibility, not a diagnosis of readers who enjoy streaks. But the underlying concern deserves weight: external incentives can increase participation while undermining intrinsic interest.
The evidence for undermining motivation
Deci, Koestner and Ryan’s meta-analysis of 128 experiments found that expected tangible rewards contingent on engagement, completion or performance reduced subsequent freely chosen engagement. Positive feedback enhanced interest on average. The findings give substantial reason to examine rewards attached to already-interesting activities; they do not establish that every badge, reminder or game element has the same effect.
Deci, Koestner and Ryan (1999): rewards and intrinsic motivation. The abstract reports effects on both free-choice behaviour and self-reported interest. Applying these findings to a particular faith-app mechanic requires testing.
A cue, a reward and a personal commitment are different
- A cue helps someone remember: “Your chosen reading time is here.” It need not offer a prize or threaten a loss.
- A contingent reward offers something for doing the activity: a badge, points or a protected streak. Ask what behaviour earns it and whether the person experiences that condition as helpful or controlling.
- A personally valued practice can matter even when it is difficult. Someone may read because the commitment expresses their faith, without enjoying every session.
Ryan and Deci distinguish intrinsic enjoyment from internalised, autonomous reasons for acting. Supporting the person’s own values is a meaningful aim; the goal is not to make every spiritual practice entertaining. Their 2020 account of intrinsic and extrinsic motivation explains this distinction.
Does gamification stop helping after a month?
There is no general one-month handover established by the studies reviewed here. In a 14-week study of 756 programming students, behavioural benefits began declining after four weeks, then partly recovered. This concerned novelty and familiarisation, not a demonstrated switch from habit support to damaged intrinsic motivation. Rodrigues and colleagues (2022).
Habit automaticity is another question. Lally and colleagues reported modelled times of 18–254 days to approach participants’ automaticity plateaus. This was not a test of gamification or of intrinsic motivation taking over. Lally and colleagues (2010). Neither result supplies a universal deadline for removing incentives.
Design support that the person can grow beyond
Make reminders and game elements adjustable independently. Preserve the reading experience when either is turned off. Offer an occasional, neutral opportunity to change the support; do not automatically withdraw something useful on day 30 or escalate rewards when activity falls.
For example: “Would you like to keep your reminders, change the rhythm, or pause them?” A reader can keep a helpful cue while hiding a streak. The product should make that combination possible.
Evaluate the relationship with the practice
Alongside participation, ask what people value, what brings them back and how they experience missed sessions. With informed participation, compare a chosen cue alone with cue-plus-reward support over time. If incentives are reduced, preserve saved work and explain the change. Include people who decline or leave; do not infer their motives from logs.
A fall in use after removing a reward does not by itself prove that motivation was undermined—it may simply show the incentive stopped working. Evidence of undermining needs a suitable comparison and measures of interest or autonomous motivation. Treat four weeks as a possible review point, not proof of a completed habit or a deadline for harm.
Decision question: are we helping this person make the practice their own, or making continued participation depend on what the app gives or threatens to take away?
Choose the mechanism by the actual need
| Mechanism | Potential use | Boundary | Evaluation question |
|---|---|---|---|
| Saved place and short sessions | Use when access or time is the barrier. | Do not turn every activity into a completion target. | Can the person resume and finish a useful task? |
| Reminders and cues | Let a person select time, wording and frequency. | Avoid guilt, unsafe notification text and difficult cancellation. | Does the cue help a chosen rhythm without unwanted pressure? |
| Plans and commitments | Offer flexible cadence, rescheduling and pause. | A missed day should not create moral debt. | Does the plan remain useful through irregular circumstances? |
| Streaks and activity summaries | Use optional factual history when the person values it. | No faith rank, paid rescue or loss threat. | How do participants experience interruption and return? |
| Badges and challenges | Tie private optional feedback to a concrete learning task. | Completion is not holiness; a nongame route remains complete. | Did recall or task competence improve, and for whom? |
| Social participation | Support chosen connection and shared reflection. | No compulsory testimony, private-practice leaderboard or unsafe audience. | Does quiet participation remain equally legitimate? |
| Repetition and reflection gaps | Name the aim: familiarity, recall, immersion or contemplation. | Do not equate minutes listened with understanding or formation. | Can the person choose gaps, repetition count and an endpoint? |
| AI personalisation | Adapt to voluntarily chosen scope and editable preferences. | No hidden health or belief profiling, intimacy rewards or endless prompts. | Does adaptation help the task while preserving control and privacy? |
A practical decision sequence
- Name the practice and who chose it: study, listening, recall, prayer, community or reflection.
- Identify the barrier through research: accessibility, time, unclear meaning, missing support, or motivation. Do not assume disengagement is a motivation defect.
- Try the simpler nongame support before adding a reward or competition.
- If using a game element, state the intended task outcome, offer opt-out and retain a complete alternative.
- Test comprehension, autonomy, unwanted pressure and outcomes over time; include people who stop or decline the feature.
- Keep theological interpretations and participant-reported meaning distinct from activity metrics.
Measure separate outcomes
Activity: sessions, passages or listening time. Task outcomes: finding a passage, source understanding or recall of a chosen edition. Experience: autonomy, burden, safety, accessibility and perceived usefulness. Formation: a separately defined theological and lived-experience question, requiring appropriate methods and long-term context.
An increase in one category is not proof of another. Include rest, non-use, life outside the app and changing circumstances in the research design. Longer sessions are not automatically better outcomes.
Progress and streaks
Choose between a saved place, completion and a shared date. Explain what the record means.
Research-informed design proposal39 · Habits and spiritual formationA flexible reading rhythm
Help someone choose a reading rhythm—and adjust it when life changes.
Proposed hypothesis40 · Habits and spiritual formationReturn without shame
Make it easy to pick up a reading practice after time away.
Proposed hypothesisTwo principles as decision lenses
Feed the flock, not on it asks whether chosen structure remains free of guilt and pressure; Plant and water; leave the growth to God asks which outcomes matter beyond usage. Together they allow optional practice support and proportionate evaluation while rejecting individual faith scores. These values do not determine a mechanism’s effects in advance.
Look beyond the app session
Attention and cross-channel engagement covers reminders, email and stopping points. Sustainable access examines funding incentives, and responsible analytics separates usefulness from spiritual scoring.
Effective at what—and at what cost?
A reminder can help someone begin. A streak can make returning feel worthwhile. The same mechanism may also encourage a person to protect a number rather than pursue the practice they chose. Useful criticism starts by naming both the benefit and the possible cost.
Retention can improve while another goal slips
Duolingo reports that separating streak maintenance from its daily goal increased day-14 retention by 3.3% relative to the comparison condition. It also reports that fewer learners met their daily goals. This is a company account of an A/B test, not independent evidence of proficiency or spiritual benefit. It illustrates why a successful engagement metric still needs a second question: what else changed?

Reward-chasing is a documented risk, not everyone’s experience
Mogavi and colleagues analysed Duolingo forum material and interviewed 15 users. Their qualitative study describes cases where pursuing game rewards distracted from learning. It helps identify possible failure modes, but does not establish their prevalence, diagnose addiction or prove that intrinsic motivation is always displaced.

Motivational benefits also deserve attention
A study of 70 Chinese English learners comparing Duolingo activities with a control condition reports gains in enjoyment and language-learner self-concept. This supports taking potential benefits seriously. Its educational setting and reported outcomes do not establish long-term effects, isolate a particular streak feature or predict effects in a Bible app.

What can brain research actually tell us here?
Howard-Jones and colleagues compared study, self-quizzing and a game-based learning task using fMRI. They report default-mode-network deactivation alongside greater engagement, and higher learning scores in the game condition. This was not a Duolingo study. It does not show that Duolingo activates an “addiction brain” instead of learning, nor that game-supported learning necessarily crowds out intrinsic motivation.
Gamification of Learning Deactivates the Default Mode Network (2016); abstract and conclusion reviewed. Neural activity alone is not a verdict on a product’s spiritual or ethical value.
Apply the lesson without importing the verdict
For a Bible app, compare the behaviour you intend to support with the behaviour the incentive actually rewards. A person may read elsewhere, listen without marking completion or return after a long pause. Those activities can matter even when the product cannot count them.
- Benefit: does the feature help people begin, remember or continue a practice they value?
- Cost: do people report pressure, unwanted interruptions, checking for its own sake or choosing easier tasks just to keep a reward?
- Freedom: can they change the rhythm, disable the incentive and still use the core experience?
- Durability: what happens after the novelty fades or the reward disappears?
Study these questions together over time. Return rates, comprehension, perceived usefulness, control and unwanted pressure answer different questions. None is a spiritual-growth score.
Evaluate a conversion funnel by observable choices: misleading prices, concealed renewal, coercive spiritual claims or obstructed cancellation. Apply the same criteria to every publisher. A critical review should document a dated flow before labelling a particular app manipulative.
