How much do the apps cost?

What platforms are these apps available on?

iOS, iPadOS and macOS. There are no plans for Android at this time.

What is the difference between Evo and the other apps?

Evo is an all in one productivity app that includes the core features from all the other apps. However the other apps, being specialised, have several features that you will not find in Evo. Solid Calendar has many more layouts, such as Day, Week, Month, Timeline, Minimal and Reminders, Ultra Focus has several social features like a global or national rank, the ability to compete with your friends, inspirational content, Lo-Fi radio in the focus timer, Formed has negative habits, the ability to make a commitment to a friend, who will be notified if you don't stick to a habit, stats about the community and tips from other users, a different set of icons, which can be used in full color or in black and white. Solid Diary has several stats and achievements related to keeping a diary, a 3 pane view and a focused view on the Mac. Finally Solid Notes has a waterfall layout and the ability to organise your notes across color coded spaces.


It wasn't possible to combine so many features into a single app with Evo, so while it does have the core functionality of all the other apps, the other apps are specialised on one thing and they do have many advantages. When deciding whether to get Evo or one of the other apps, please consider whether you'd prefer to have an all in one with a clean timeline, day based layout, or a dedicated app that does one thing really well.


Evo does not sync data with the other apps.

How does voting on new features work?

"I love this app. The design is amazing, so simple to use and the fact that it doesn't require a subscription to use it makes it the best habit tracker out there."

"This suite of apps for just over a tenner is brilliant value. They are minimalistic and instantly usable with practically zero learning required. A well-designed and executed suite of apps that show the way that the industry should head in. No more apps for geeks but apps for ordinary people who have better things to do with their time than trying to figure out how to use an app to achieve a simple outcome."

"I am in love with your Ultra Focus app features, interface, color, and especially Lofi Radio and timer playing in the Dynamic Island and in the Lock Screen. I am so glad I found Solid apps! Appreciate the hard work, and thank you so much for such wonderful apps."

"What an amazing bundle of apps. I never get an app with any subscriptions so to find these apps for a one-off payment is brilliant. Fantastic work so far."

"Really well-done app, it's rich in features but keeps a slick design, and the developer is very responsive. Keep up the great work!"

"I've been looking for a Fantastical replacement for years but none of the calendar apps had natural language support or the type of layout I liked. I finally found my new go-to calendar app in Solid Calendar!!! I love how it's so well designed and the fact that it literally has everything I need in a calendar. Thank you!"
