Compare documented iPhone astrology app features, prices and privacy labels, alongside a limited desktop chart check and a selection worksheet.

Documented iOS listings and a limited desktop chart check, with clear limits on what was tested.

Introduction

Disclosure: this is AskSoma's own comparison guide and links to its own calculator. The desktop results below are publisher-reported observations, not independently verified testing. Store descriptions are attributed to their publishers.

For an iPhone astrology app, start with how you want to use it: read an astrologer-written reflection, inspect chart settings, or ask follow-up questions. CHANI and AstroSage both link to iOS apps from their official sites. This guide compares documented workflows, then shows what to check before choosing a subscription.

What do the official store listings actually say?

The [AstroSage App Store listing](https://apps.apple.com/us/app/astrosage-kundli-ai-astrology/id824705526), checked 8 September 2026, names Ojas Softech and requires iOS 15.6 or later. Its publisher describes chart controls, AI chat and PDF export. These are documented features; we did not install the iPhone app.

The [CHANI App Store listing](https://apps.apple.com/us/app/chani-your-astrology-guide/id1532791252) names Chani Nicholas Inc, requires iOS 15.1 or later and lists US subscriptions at $11.99 monthly or $107.99 annually. Confirm your local checkout price. AskSoma's verified store source here is Google Play; it does not establish native iOS availability.

What can't be verified yet, and why that matters

The desktop comparison below is a limited calculation check. It does not establish native iPhone behavior, cancellation friction, privacy practices or forecast accuracy. Publisher descriptions and developer-supplied privacy labels document stated features and policies; they are not independent audits.

What happened in a same-input browser comparison?

The publisher reports entering one synthetic chart on 8 September 2026 into AskSoma and AstroSage in a desktop browser on macOS: 1 January 2000, 12:00:00, UTC+0, latitude 51°30′ north, longitude 0°08′ west. Both generated a chart without sign-in. This was an AskSoma-owned check, not an independent audit or a native phone-app test. AstroSage used N.C. Lahiri and North Indian style; AskSoma displayed Lahiri, whole-sign Rashi/Placidus Chalit and mean nodes. Differing chart settings and calculation implementations limit direct comparison of the degree differences.

Position	AstroSage	AskSoma	Absolute difference
Ascendant	Aries 00°08′07″	Aries 00°08′47″	40 arcseconds
Sun	Sagittarius 16°31′38″	Sagittarius 16°31′11″	27 arcseconds
Moon	Libra 19°27′54″; Swati 4	Libra 19°28′29″; Swati 4	35 arcseconds

The checked signs and Moon's nakshatra/pada agreed; the exact degrees differed. No independent ephemeris reference was calculated, so neither a winner nor the cause of the differences can be established. The Ascendant was only about eight arcminutes into Aries. For an uncertain birth time, record this boundary proximity before relying on the matching sign alone.

The publisher reports that an AstroSage planetary-position click opened a consultation page before reaching the position table, while AskSoma showed positions in its calculator result. This describes one desktop session. We did not test PDF export, saving, account deletion, payments, iPhone Safari or native Android apps.

To repeat the check, open [AstroSage's form](https://www.astrosage.com/kundli/) and [AskSoma's calculator](/kundli-calculator), enter the fixture above and record the positions before changing settings. Use manual coordinates and timezone to avoid city-lookup differences. Retain the date and outputs if results change, then investigate settings before deciding an engine is wrong.

How do tropical, sidereal, ayanamsa and time zone actually affect your chart?

Tropical and sidereal zodiacs use different reference points. Many Vedic astrology systems use a sidereal zodiac, but traditions and software differ. The same birth data can therefore produce different signs depending on the zodiac and ayanamsa setting. A wrong time zone or daylight-saving setting can materially alter a chart; this article does not establish how often that error occurs compared with an ayanamsa choice.

• Confirm whether the app defaults to tropical or sidereal — AstroSage's Kundli form exposes an explicit ayanamsa selector, per the publisher's own page.
• If sidereal, record the ayanamsa. Lahiri is offered by the two calculators described here; this comparison does not establish its prevalence.
• Enter the recorded local clock time, then verify the app's time zone and historical daylight-saving setting against a reliable record; if uncertain, treat the result as provisional.
• For uncertain birth time, prioritize civil or family records. Astrological rectification is an optional traditional interpretation, with no established guarantee of recovering the true time.
• Re-check the [vedic birth chart](/vedic-birth-chart) output against your birth certificate time before relying on Dasha or transit dates.

How does the tropical-to-sidereal offset actually work, in plain arithmetic?

The core idea is subtraction: a sidereal position equals the tropical position minus an ayanamsa offset. The figures below are an illustrative fixture to show the mechanic, not a calculated Lahiri value for any real date — don't use it as your chart.

Which app fits which kind of iPhone reader?

The right pick depends on whether you want daily reflection, technical chart control, conversational explanation, or a human on the phone — no single app documented here covers all four equally well based on current evidence.

Scenario 1: You want a short daily reading and don't care about chart mechanics

If your goal is a quick, astrologer-written horoscope, transit note or meditation prompt each day, CHANI's stated focus — readings and meditations authored by Chani Nicholas and her team, per the official app page — matches that use case better than a chart-calculator-first tool. Pair it with a browser check of your [daily horoscope/moon](/daily-horoscope/moon) or [daily horoscope/sun](/daily-horoscope/sun) page if you want a second, free reference point.

Scenario 2: You want to inspect Dasha periods, ayanamsa settings and export a PDF

AstroSage's web form exposes an ayanamsa selector. Its iOS listing describes chart controls, but the app's specific settings were not independently tested. Confirm the controls you need on the device, and read its tracking-related privacy label before entering personal information.

Scenario 3: You want to ask follow-up questions in plain language, or talk to a person

If you'd rather ask 'why does this matter' in your own words, Ask Soma's browser-based Kundli — built on Swiss Ephemeris calculations and explained through AI chat and voice, per its Google Play listing — currently works through a mobile browser rather than a verified native iPhone App Store app, so add it to your Home Screen for an app-like feel using the checklist below. For a human consultation, compare a practitioner's scope and quoted price directly; this guide does not recommend a particular marketplace.

A concrete iPhone checklist before you subscribe

Before paying for any astrology app on iPhone, run through these checks using the app's own store page and settings screen — most of this takes under five minutes.

• Check the App Store's minimum iOS version against your phone's installed version (AstroSage's listing requires iOS 15.6+, per Apple).
• Open the App Privacy section on the store page and read what data is linked to you versus used for tracking, rather than assuming 'astrology app' means low data collection.
• Look for a visible ayanamsa or chart-style setting if you follow Vedic (sidereal) astrology specifically.
• Confirm whether the free tier gives a full chart or only a teaser, and whether PDF export is free or paid.
• Before subscribing, identify whether billing is through Apple or the vendor and review the corresponding cancellation steps. If billed through Apple, manage it under Settings > your name > Subscriptions.
• If no native iPhone app is confirmed, add the site to your Home Screen from Safari's Share menu for a full-screen, app-like shortcut.

A simple cost-per-use worksheet

Before committing to a monthly plan, estimate what you'll actually pay per session rather than judging by the sticker price alone.

Step	What to record	Example
1	Choose one billing period	For a monthly estimate, use the monthly price or annual price divided by 12.
2	Estimate uses in the same period	For example, 12 uses per month. A daily habit would be closer to 30.
3	Divide the monthly cost by monthly uses	At 12 uses/month, $11.99/month is about $1.00/use. $107.99/year is about $0.75/use over 144 annual uses. Annual billing still requires the upfront payment.
4	Include additional charges	Add taxes, separately billed consultations and any other fees. Compare a free tool offering the same task.

What's a fair, honest bottom line?

This guide does not establish an accuracy winner. Use CHANI's publisher-described readings, AstroSage's chart tools or AskSoma's explanation workflow as starting points, then check the settings, billing and privacy details that matter to you.

Frequently asked questions

Is there a verified Ask Soma app in the iPhone App Store?

The evidence used for this article documents Ask Soma on Google Play, describing a Swiss Ephemeris–based Kundli explained via AI chat and voice. No verified native iOS App Store listing was found, so treat it as a browser/Home Screen experience on iPhone for now, and check the App Store directly for the latest status.

Which app lets me choose the ayanamsa myself?

AstroSage's web form exposes an ayanamsa selector. Its iOS listing describes chart controls, but the app's specific settings were not independently tested. Confirm the available settings on your device.

Do these apps' star ratings tell me anything about chart accuracy?

Not reliably. Store ratings mostly reflect user experience, design and general satisfaction, not independent verification of astronomical calculations. Treat ratings as one input, not proof that a chart's Dasha or planetary positions are correct.

What is Lahiri ayanamsa, and why does it matter?

Lahiri is an ayanamsa (precession correction) in Vedic astrology, converting a tropical zodiac position to a sidereal one. Its exact value shifts slightly year to year in a real ephemeris like Swiss Ephemeris + Lahiri; any fixed number you see in an example should be treated as illustrative, not your actual chart.

Should I trust an app's privacy label completely?

Treat it as a helpful but self-reported summary. Apple states that privacy labels are provided by developers and are not independently verified by Apple, so read the specific data categories listed (like tracking-linked contact info) rather than assuming a green checkmark means full privacy.

What should I do if I'm not sure of my exact birth time?

Start with civil or family records. Small time differences can change placements near a boundary. Astrological rectification is a traditional interpretive approach, not a validated guarantee of recovering the true birth time.
