getActi.app VS Diffyn

getActi.app's answer

Acti is the only travel tracker that’s fully automatic, privacy-first, and account-free.
Most apps require sign-ups, send your location to servers, or focus only on workouts or check-ins. Acti works differently:

• Automatic tracking — visits are detected and logged without manual check-ins.
  
• Privacy-first — all data stays on your iPhone, nothing is uploaded.
  
• No account needed — start using it instantly, no registration or social login.
  
• Rich context — integrates with Calendar and Health apps to give you the full picture of where you were and what you did.
  
• Beautiful visualization — your travels are shown on a personal map with statistics and history.

Diffyn's answer:

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

getActi.app's answer

I’m a developer who wanted to securely journal every place and moment of my life.
Acti started as my personal tool — and over the past 3 years it has helped me document 1,000+ places, living abroad, the birth of my daughter, and unforgettable Europe trips.

Most apps felt too invasive or complicated, so I built Acti differently:

• Automatic — visits are logged in the background.
  
• Private — everything stays on your iPhone.
  
• Personal — with photos, notes, and ratings to give each place meaning.
  

What began as a way to keep my own memories safe has become a journaling app for anyone who wants their life remembered — securely and beautifully.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

getActi.app's answer

Acti doesn’t have “big customers” — it’s a personal iOS app used by individual people around the world who want a private way to keep their life journal.
