Everything in the app

Today's plan

A short checklist for the day, split into morning, afternoon, and evening. Most lines tick themselves off when you log a meal, a workout, a game, or a night's sleep, so nothing gets entered twice.

Seventeen built-in items

Choose from five groups: food, body, mind, night, and everything else. Some, like “Talk to someone” or “Get outside,” are things no sensor can see, so you tick them yourself.

Your own goals

Write your own and pick what completes it, like 20 minutes of exercise or three game rounds. A goal like “Call my sister” simply waits for your tap.

Routines

Choose a 5, 15, or 30-minute routine, or save your own under a name like “Gym day.”

Reminders

Tap the bell on any line to turn it into a daily reminder at a time you pick.

Diet log

Log what you eat by name, by scanning a barcode, or by searching a public nutrition database. Calories and macros are tracked against daily goals you set.

Barcode scanning

Point your camera at a package and the app looks it up in Open Food Facts, a free public food database.

Food search

Search the USDA's FoodData Central for raw ingredients, everyday dishes, and anything cooked at home, then set the portion.

Calories and macros

Track protein, carbohydrate, fat, and fiber. Each goal shows green, amber, or red depending on how close you are.

MIND diet marks

Optionally count foods from the MIND diet, an eating pattern studied for brain health. You can switch this off entirely.

Calorie estimate

A calculator estimates your daily energy needs using the Mifflin-St Jeor equation. It's an estimate, not dietary advice.

Talk to a doctor or dietitian before changing how you eat, especially if you take medication, are pregnant, or manage a long-term condition.

Exercise, strength, and weight

The exercise log answers “did I move today?” Strength answers “am I getting stronger?” They're kept apart on purpose, because one is measured in minutes and the other in sets, reps, and pounds.

Apple Health

Connect it and the app reads your exercise minutes, active calories, steps, walking and running distance, and workouts. It only reads, and never writes to Health.

Sessions by hand

Forgot your watch? Add a session yourself and it joins the totals for your weekly goal.

Strength log

Record sets, reps, and weight for each lift. Build routines like “Push day” so a whole session is laid out, ready to fill in.

Two numbers for lifting

Pounds lifted shows how much work a session was. Lift score shows how heavy it was. Together they tell you whether you're getting stronger or just training longer.

Training blocks

Name a stretch of weeks, like a 12-week program, and read its charts on their own.

Weight

One weigh-in a week on a day you choose, with an optional reminder. Weekly readings show the trend without daily water-weight swings.

Sleep center

Two sides: a log for how you slept, and sounds to help you drift off.

Sleep log

Record your hours and how the night felt.

Sleep journal

Optionally note your bedtime, when you woke, and what you did beforehand.

Sleep sounds

Waves, rain, brown noise, or white noise on a timer. Waves and rain are generated by the app, so there's nothing to download and the loop never audibly repeats.

Plays while locked

Once you switch it on, sound keeps playing with your phone locked.

Synaptiva makes no claim that the sounds will help you sleep, and they aren't a treatment for insomnia or any other condition. Keep the volume low.

Twelve games

Grouped by what they ask of you. Most get harder when you're doing well and easier when you're not. The three music games need an internet connection; the rest work anywhere.

Music categories

Play built-in categories like 80s rock, 90s R&B, or K-pop, or build your own from a few artist names.

Games elsewhere

Crosswords, chess, puzzles: log games you play outside the app. They're kept in their own category, apart from the scores the app measures.

Shuffle

Not sure what to play? The shuffle button picks for you.

Personal records

Your best result in each game is kept, so you can see how far you've come.

Song previews, artwork, and details are provided by Apple. Clips are the 30-second previews Apple publishes, streamed as you listen and never stored, and every round credits the track. Apple Music and iTunes are trademarks of Apple Inc. Synaptiva is not affiliated with or endorsed by Apple.

Auditory stimulation

Sound on a timer, with a record of how long you listened. The screen explains what each sound is and what is and isn't known about it.

40 Hz clicks

A click 40 times a second. Gamma is the name for brain activity in roughly the 30 to 100 Hz range, and research is looking at whether rhythmic sound at that rate affects it. That research is ongoing.

White noise

An even hiss across all frequencies, like an untuned radio.

Brown noise

Weighted to the low end. Deeper and softer than white noise, more like rainfall.

Binaural beat

A slightly different tone in each ear, heard as a single pulsing tone. It needs headphones, so the app asks before it starts.

Synaptiva plays these sounds and makes no claim about what they will do for you. If you have epilepsy, tinnitus, a hearing condition, or any concern about your health, talk to a doctor before using them, and keep the volume comfortable.

Cognitive baseline

Eight short tests at a fixed difficulty, scored out of 100: numbers, words, new vocabulary, squares, the ring, speed, sorting, and estimates. Because the difficulty never changes, one sitting can be compared with the next. Ordinary games can't do that, because you get better at them.

Once a month is the suggestion. Taking it sooner mostly measures practice rather than change. Sit it somewhere quiet when you're reasonably awake, because tiredness moves these scores more than almost anything else.

Progress and insights

Several ways to look back, each honest about how much data sits behind it.

This week

A live rollup of the last seven days against your goals.

Weekly report

Each finished week, Monday to Sunday, compared with the week before. Save it as a PDF.

Long-term

A small summary of every finished day, kept for five years, so you can look back across months on a calendar.

Cognitive dashboard

Your scores by area: spatial memory, learning and recall, processing speed, recognition, and estimation.

How much data

Every trend is labeled from “No data” to “Reasonable data,” so you know how much to read into it.

Insights Beta

Opt in and the app compares your habits with your scores, for example by splitting your days by how long you slept. It explains what it changes before you agree, including keeping your logs for a year.

Scores climb with practice as much as anything else. A rising score in a game you play often mostly means you're getting better at that game, and the app says so throughout.

Points, streaks, and achievements

A point total for everything you log, a bulb that grows with consecutive days, and achievements measured against your own history. None of it is compared with anyone else.

Synaptiva score

Points for meals, workouts, sleep, games, and listening. A meal counts once however many foods are in it, and listening stops earning after a daily cap.

Achievements

Forty milestones, from your first round to your ten-thousandth.

Make it yours

Change how the app looks, how much of it you see, and how large the text is.

Themes

Seven to choose from: Forest, Ocean, Plum, Clay, Lumen, Graphite, and High contrast.

Backgrounds

Plain, dots, grid, diagonals, waves, rings, or a photo of your own.

Typefaces and text size

Standard, rounded, serif, or monospaced type. Follow your phone's text size or choose one of seven sizes, up to very large.

How much you see

Just the basics (the logs and games), Everyday (adds the plan and the week), or Everything (adds the baseline and analysis). You can rearrange the home screen too.

Simple mode

Every screen has a small ⓘ button explaining what it does and where it stops being reliable. Simple mode shows that text right on the page.

Your reason why

Add a photo and a line about why you're doing this, like a person or a place. It shows on your home screen and never leaves your phone.

Your data stays on your phone

There's no account and no server. Everything you log is stored on your phone, and deleting the app removes all of it.

What leaves your phone

Only a song search, a barcode, or a food name, each sent only when you use that feature, to Apple, Open Food Facts, or the USDA.

Protected by your passcode

iOS encrypts the app's data with a key tied to your phone's passcode. Photos you add get the strongest protection iOS offers.

You choose how long

Logs are kept for seven days by default, or longer if you choose. Long-term summaries are kept for five years.

Reset and export

My data has a reset button for each part of the app, and can export everything you've logged as one file.
