Scoped review · 28 October 2026Trust & care
Source boundaries, privacy and safeguards need further review. No app-wide assurance is implied.
Evidence incompleteOffers are dated iOS observations in USD where captured. Eligibility, country and platform can differ. Existing settings are not installation defaults.
Where the observed choices sit
Each row is one scoped observation of a specific flow, not a grade for the whole app.
No practice has been placed on the scale yet.
1 area reviewed, not yet placed7 areas not reviewed yetReview notes
Works against: a choice subverts the person’s agency. Respects: it respects people and safeguards. Restores: a practice restores at a cost freely borne by the builder. Price, Christian branding or a free tier alone do not place an area. How we review.

What access does payment cover?
The retrieved sources do not establish which capabilities require payment. This is unknown, rather than a claim that the app is free or paid throughout.
Free samples, a free tier and the complete library are different scopes. Store and publisher evidence is separate from the dated captured-flow review in Design review. Coverage varies by offer and platform.
Publisher funding and business model
No source-backed funding or business-model summary is available in this profile yet.
The organization’s complete current funding mix and revenue are not established here. App payments, donations and capital raised describe different things; they do not determine an ethical assessment.

The ten principle questions For your own design review
These questions guide discernment; they are not ten scores for this app.
- Keep the Word distinct, and teach it truly
- Can a reader always tell Scripture from our words, and our words from a machine’s?
- Never speak for God
- Would we put our own name under this sentence, or are we borrowing God’s?
- Design for the most vulnerable first
- Who is the most vulnerable person likely to use this today, and what will they see?
- Welcome before you ask, and guard what is told in confidence
- If a friend read everything we keep about this person, would the person be glad?
- Feed the flock, not on it
- Does this serve growth in faith, or only the usage numbers?
- Make room for rest, and say when it is enough
- Where does our product stop, and does it ever tell someone they have done enough?
- Send people to God and to one another
- When someone closes what we built, are they closer to God and to other people?
- Plant and water; leave the growth to God
- What would we stop measuring if we believed growth is God’s?
- Make it well, as an offering
- Would we offer this to God as it is, and could the person with the least sight, time or reading ease use it?
- Hold it with joy and trembling, before God and others
- Who outside the team holds us to account, and who prays for the people who use this?
Use this in your own work
Start with the observed choice, then ask how your own implementation serves people. The evidence is a design example, rather than an app-wide recommendation.
