Estimate a project margin

CutMargin ↗

Source check · 25 October 2026

What is free?

The calculator is free and requires no account. An optional $29 kit is separate from the calculation.

Where is the limit?

It uses entered fees, expenses and hours; it does not measure time or guarantee earnings. Currency choices do not perform foreign-exchange conversion.

Data handling and source

The provider says calculation inputs stay in the browser. Umami collects separate interaction metadata.

Official provider source ↗

A small check to try

Enter a fictional fee and time estimate. Check the calculation before using your own costs.

Suggested check, not a claim that this complete workflow was tested.

Keep track of coaching enquiries

FlowKit Studio ↗

Source check · 25 October 2026

What is free?

Free early access, according to the public product page. No paid subscription amount was verified.

Where is the limit?

The current landing page targets coaches, yoga and Pilates. It does not provide scheduling, payment processing or push reminders. CSV and JSON exports are documented.

Data handling and source

Records remain in this browser according to the provider. Do not enter health records; there is no verified cloud backup.

Official provider source ↗

A small check to try

Create a fictional prospect and follow-up date. Try the documented export before keeping real records.

Suggested check, not a claim that this complete workflow was tested.

Convert HEIC photos

HEIC.AI ↗

Source check · 25 October 2026

What is free?

Free, without an account or watermark. The published intake limit is 200 files and 50 MB per file.

Where is the limit?

These are intake limits, not a guarantee that every device can process a maximum-size batch. Conversion re-encodes files and removes EXIF metadata according to the provider.

Data handling and source

Image conversion is described as local. Website analytics and advertising are separate; the site is not represented as tracking-free.

Official provider source ↗

A small check to try

Start with a non-sensitive sample. Check orientation, dimensions and image quality after conversion.

Suggested check, not a claim that this complete workflow was tested.

Create a small number of invoices

InvoiceAdept ↗

Source check · 25 October 2026

What is free?

Free account: 5 invoices/month and 1 user. Pro: GBP 7.99/month with monthly billing, 3 users and unlimited invoices. Pro+: GBP 12.99/month with monthly billing. Prices exclude VAT; a 14-day paid-plan trial is advertised without a card.

Where is the limit?

Stripe and WhatsApp features are not included in the free account plan. The product supports records and exports but does not file returns with HMRC. Tax and CIS results need user review.

Data handling and source

Account and invoice information is held by the service. The privacy policy identifies hosting and other processors, including Stripe and OpenAI. This check did not send an invoice or process a payment.

Official provider source ↗

A small check to try

Use fictional customer details to inspect the fields and export. Check your tax requirements separately.

Suggested check, not a claim that this complete workflow was tested.

Map ideas and relationships

RelationCanvas ↗

Source check · 25 October 2026

What is free?

Free public access, without an account or export watermark.

Where is the limit?

Arrow labels are limited to 100 characters. Longer notes remain in the project rather than appearing in the exported image. Export and large-map reliability were not independently tested.

Data handling and source

The provider describes local project work. Keep an exported backup and inspect any sharing link before sending it.

Official provider source ↗

A small check to try

Draw a small example, then check that an export keeps the labels you need.

Suggested check, not a claim that this complete workflow was tested.

Compare two versions of text

TextCompare ↗

Source check · 25 October 2026

What is free?

Free public tools; no account, payment system or subscription is documented.

Where is the limit?

File-format fidelity and large-document limits vary by tool and were not comprehensively tested. A textual comparison is not a semantic correctness check.

Data handling and source

The privacy policy says comparison content is processed locally. Google Analytics and Cloudflare handle website measurement and technical requests separately.

Official provider source ↗

A small check to try

Paste two non-sensitive paragraphs. Check the highlighted differences against the originals.

Suggested check, not a claim that this complete workflow was tested.
