Seraph vs Blue Letter Bible
A study library that links tools to every verse, with a download price of zero on the US listing, and a quieter flame that never asks for an account. This page is written by the maker of Seraph — read it knowing that — and it will be generous to Blue Letter Bible, because the library is real and they do not sell a subscription on the pages cited here.
Our bias, declared: we make Seraph. The linked Blue Letter Bible sources support the specific download price, store listings, website wording, account wording, and privacy wording identified below; this is not an independent review of either app. Our product details describe Seraph’s current published offering. If we've got something wrong, tell us and we'll fix it.
The main difference
Consider Blue Letter Bible if you want Scripture with a lexicon, commentaries, and more than one translation beside the verse. The US listing (id365547505) on this check has subtitle “In-Depth Study Bible,” seller Blue Letter Bible, category Reference, age 4+, copyright © 2026 Blue Letter Bible, bundle id com.BlueLetterBible.BLB. JSON-LD Offer on that page is price 0, currency USD. Offer data sets isFree to true, hasInAppPurchases to false, and hasExternalPurchases to false. The offer title is “Get.” This check found no In-App Purchases list. We do not invent a monthly or yearly price. Listing copy: over 30 Bible versions, audio Bibles, text and audio commentaries, a Hebrew and Greek lexicon, concordances, dictionaries, and advanced word searches. We do not have Android, Hebrew and Greek tools, or a multi-translation study library.
Choose Seraph if you want something quieter: one flame kept daily, the whole King James Bible readable free, guided prayer paced by breath — and a hard privacy line: no account to create, no ads, and a public vow of no prayer analytics. Your prayer life stays on your device. Seraph+ is $6.99/mo or $59.99/yr on our US App Store listing and on our pricing page. The daily office is free. Sacred Seasons, including Advent, are not. There is no Seraph+ trial. Blue Letter Bible is a study library funded, on their own FAQ, by gifts. We are a silent daily office with a paid season. That is the fork.
Side by side
| Feature | Seraph | Blue Letter Bible |
|---|---|---|
| Annual price | $59.99/yr | None published on the pages cited here. The US listing JSON-LD Offer is price 0 / USD for the download. isFree is true. hasInAppPurchases is false. The Play listing button on this check reads Install. This check did not find a dollar price or an In-app purchases chip on that Play page. Their general questions describe gifts, not a yearly plan. We do not invent a yearly price. |
| Monthly price | $6.99/mo | None published on the pages cited here. No monthly SKU appears on the US listing. Their apps page says the study resources are “always free.” We do not invent a monthly price. We also do not invent a suggested gift amount: this check did not open a donate checkout. |
| Family plan | — | None published. There is no subscription on the US listing to share. We do not invent a family SKU. |
| Free trial | None — the free tier is the trial | Not applicable. No paid library is named on the US listing, the Play listing, or the apps page. There is nothing on those pages to trial. |
| Free, forever | Daily verse · 2 guided sessions · the whole KJV Bible (1,189 chapters) · every reading plan · streak flame · reminders | The download they price at 0, plus the study tools named on the stores. Their apps page: “Our Bible study resources are online, in-depth, and always free.” The same page’s banner: “Did You Know BLB Is User Supported?” The US listing names CSB as free and installed, and ESV, LSB, NASB, and NASB2020 as free downloads, among over 30 translations. The Play listing says “over 15 available Bibles.” Those counts are not the same claim. |
| Subscription opens | Full guided-prayer library (12 sessions) · Sacred Seasons (Advent & Lent) | Nothing, on the pages cited here. hasInAppPurchases is false on the US listing. Their funding answer is gifts from donors, including the sentence “In 2018, over 50% of our budget needs were met by gifts from individual donors.” That sentence is about 2018. It is not a current budget we measured, and it is not a price. |
| Account required | No — no sign-up exists | Not to use most of what they publish. Their privacy policy: “Most of the services and apps provided by Blue Letter Bible can be used without ever creating an account.” The same policy’s account data, when you do create one, is “Name, user name, and password” to maintain preferences and selections. Their donor FAQ: “Your BLB account is meant to save your daily reading, devotional emails and Bible study preferences,” and that donor account is not the same account. The US listing also says preferences can be backed up “locally from iCloud,” and the description says “Cloud back up.” We print both. We do not treat iCloud and a BLB account as the same thing. |
| Spoken Scripture | None as a spoken Bible product. Breath-paced guided prayer. Full KJV readable, not narrated as a catalogue of voices. | Named on the US listing: audio Bibles, and “Listen to the Bible and audio commentaries.” What’s New on that check: “Added browsable text and audio commentaries!” The Play description on this check does not say audio. We do not copy the iOS audio line onto Android. |
| Prayer analytics | None — a public vow. Prayer data never leaves your device | They are a study library, and the labels disagree with each other. Apple’s privacy header on the US listing: “The developer, Blue Letter Bible, indicated that the app’s privacy practices may include handling of data as described below.” The only privacy-detail bucket on this check is Data Not Linked to You. Under Analytics: Identifiers — Device ID; Usage Data — Product Interaction. High-level categories on the product page: Identifiers, Usage Data. This check did not find a Data Used to Track You shelf or a Data Linked to You shelf. The Play Data safety block, which says the developer provided it and may update it: “No data shared with third parties.” “No data collected.” “Data is encrypted in transit.” “You can request that data be deleted.” Their privacy policy is a third wording: passive log and cookie data for websites and mobile applications, and active data that includes preference, contact, account, and donor fields. “It is Blue Letter Bible's policy to never sell, rent, or trade any of our users' contact information and donation information, including email or mailing address lists.” We print those three pages. We do not invent that they describe the same collection. We do not restate rating or ranking marketing from the store listings. |
| Scripture | Full KJV bundled; offline on iPhone | Many translations, and the counts are not one number. The US listing: “over 30 Bible translations” in English, Spanish, Chinese, Korean, German, Russian, French, Hebrew, and Greek, with CSB installed and ESV, LSB, NASB, and NASB2020 named as free downloads. The Play listing: “over 15 available Bibles,” plus “Over 8,000 text commentaries by over 40 different authors,” a Hebrew and Greek lexicon, interlinear, dictionaries, and the Treasury of Scripture Knowledge. The translation menu on the privacy policy page lists 35 versions on this check, including King James Version, NKJV, NLT, NIV, and ESV. We quote each page for its own list. We do not invent that 30, 15, and 35 are the same library. |
| Platforms | iPhone and web | The US listing Information section names iPhone (iOS 15.6 or later), iPad (iPadOS 15.6 or later), iPod touch (iOS 15.6 or later), Mac (macOS 12.5 or later and a Mac with Apple M1 chip or later), and Apple Vision (visionOS 1.0 or later). JSON-LD availableOnDevice on that page is “iPhone, iPad, iPod.” JSON-LD operatingSystem is “Requires iOS 15.6 or later. Compatible with iPhone, iPad, and iPod touch.” The lockup tertiary title is “Designed for iPad. Not verified for macOS.” We print all three. The Play listing is Android, package org.blueletterbible.blb, developer Blue Letter Bible, content rating Everyone, category Books & Reference, “Updated on Sep 1, 2026.” Their apps page links Apple iOS and Google Android. blueletterbible.org is the website. |
| Tradition | Broadly Christian, KJV | A ministry of Sowing Circle. Their general questions: “The Blue Letter Bible is a ministry of the non-profit organization Sowing Circle,” and “We have chosen not to be affiliated with any denomination or ministry.” The same page says statement of faith, mission, and resources “are grounded in the historical, conservative Christian faith.” Seller on the US listing is Blue Letter Bible. Not Bible Gateway, not YouVersion, not Dwell. We do not restate chart position or review marketing from that page. |
| If you cannot pay | No scholarship or sponsorship path published. Advent and most guided sessions require Seraph+. | The study library they publish is already free to download. Their funding answer: since 2010 they have raised support from outside sources, after Sowing Circle had funded operating costs. Their donor FAQ: donations are tax-deductible as a 501(c)(3), and “BLB has never and will never share or sell a donor's personal information with anyone else.” Gifts are optional. We found no scholarship sentence, and no subscription price to waive. |
Blue Letter Bible’s download on the US listing is price 0, with hasInAppPurchases false. Seraph+ is $59.99/yr or $6.99/mo, auto-renews, cancel anytime. Those are not a matched pair, and we do not invent that zero and $59.99 are the same kind of product. Their website FAQ places advertisements only in sections labeled “Sponsors.” This check did not find a Contains Advertising line on the US listing, and did not find a Contains ads chip on the Play listing. We do not turn that into a claim that the apps are ad-free, and we do not turn the website Sponsors row into a claim that the apps carry ads.
What Blue Letter Bible does better
Study depth, more than one translation, Android, audio on iOS, and a download price of zero. If “read the passage with a Hebrew and Greek lexicon, the Treasury of Scripture Knowledge, and commentaries on the same screen” is the requirement, their US listing and Play listing are built for it. The iOS page says over 30 translations. The Play page says over 15 Bibles and over 8,000 text commentaries by over 40 authors. They ship Android. The iOS listing names audio Bibles. Their apps page says the resources are always free. We charge for Sacred Seasons and for the rest of the guided library. There is no Seraph+ trial: you never try a paid session before buying it. If you want an in-depth study Bible, Blue Letter Bible is the honest recommendation, and we are not in that contest.
They are also not Bible Gateway (HarperCollins, with ads on the free reader and a Plus subscription on the pages we cite there), not YouVersion, and not Dwell. Those are different products. This page is Blue Letter Bible, a ministry of Sowing Circle.
What Seraph does differently
Restraint as a feature, and a Bible you can finish with your eyes. No account between you and prayer — their privacy policy says most services and apps can be used without an account, and an account still exists for preferences, daily reading, and devotional email. Ours has no sign-up screen. Prayer data never leaves the device. Their US listing reports Device ID and Product Interaction not linked to you, and their website policy describes logs, cookies, and account fields. Two prices, written in plain numbers: $59.99 a year or $6.99 a month, auto-renew, cancel anytime. The entire KJV free — readable, bundled offline on iPhone, every chapter — rather than a menu of 35 versions on the website and a different count on each store. A public web office you can open without installing an app. A streak that forgives a missed day instead of shaming it. No ads on free or paid. Guided prayer paced by breath. Compare the plan and features that fit your use. They do not sell a plan on the pages cited here.
Three disclosures that belong here. The web subscription and the iPhone subscription are separate purchases and do not unlock each other. The complete offline Bible is the iPhone app; on the web, chapters you have already opened stay readable. And restoring a web subscription in a new browser emails a magic link, so we will not claim “no email ever.” There is no Seraph+ trial.
When each app wins
Blue Letter Bible — if you want study tools on the verse, more than one translation, or Android
Start from the US listing, the Play listing, or blueletterbible.org/apps-tools.cfm. Read without paying. Create the account only if you want preferences, daily reading, and devotional email saved. Use Android if that is your phone. Expect sponsor placements on the website, in the sections their FAQ labels “Sponsors,” and do not assume the store listings say the same thing about ads. Do not come here first for a silent one-flame office with no account and a public vow that prayer never leaves the device. They are Sowing Circle’s study library, and the pages say so.
Seraph — if you want a quiet office with no account, a full readable KJV, and a price you can read before you install
Ours, last on purpose. A flame, the KJV, two free guided sessions, reading plans, no sign-up. Paid for the remaining sessions and Sacred Seasons, free for the office. Small, new, iPhone-and-web only. If none of those sentences is what you came for, Blue Letter Bible is the better fit, and we would rather you found it here than felt sold to.
